Detailed ways

The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The terms "first", "second" and the like in the description and the claims in the embodiments of the present application are used to distinguish different objects, rather than to describe a specific order.

For ease of understanding, related terms and the like that may be involved in the embodiments of the present application are first introduced below.

(1) Ball machine

The dome camera is also known as a spherical camera. It integrates an integrated camera (including a zoom lens), a PTZ, a decoder, a protective cover and other functions. Among them, the PTZ can also be called a turntable, which is the support for installing and fixing the camera. Equipment, the gimbal can be divided into fixed gimbal and electric gimbal. The fixed gimbal will lock the position after adjusting the horizontal angle and pitch angle of the camera. Therefore, the monitoring range corresponding to the fixed gimbal is fixed and limited; electric cloud The platform can control the camera to rotate horizontally or vertically through the program or keyboard to change the monitoring range. Therefore, the monitoring range corresponding to the electric PTZ is wide and changeable. It should be noted that the dome camera in the embodiment of the present application selects a rotatable pan/tilt.

In security monitoring applications, PTZ is the abbreviation of Pan/Tilt/Zoom, which means PTZ azimuth (horizontal/vertical) movement and lens zoom control, referred to as PTZ control. Among them, Pan represents the horizontal movement control of the PTZ, Tilt represents the vertical movement control of the PTZ, and Zoom represents the zoom control of the lens.

The embodiments of the present invention are not only applicable to the dome camera, but also applicable to other cameras that can adjust the field of view. Adjusting the field of view includes adjusting the horizontal field of view of the camera, adjusting the vertical field of view, or adjusting the zoom of the lens.

(2) point (point)

The point position includes one or more of the horizontal angle, the tilt angle and the focal length of the lens. The so-called point position setting: its essence refers to setting the PTZ parameters of the dome camera, that is, setting at least one of the three parameters of the dome camera lens's horizontal angle, pitch angle and lens focal length at this point, among which, the horizontal angle Corresponds to the parameter P (translation) in the above PTZ, the pitch angle corresponds to the parameter T (tilt) in the above PTZ, and the focal length of the lens corresponds to the parameter Z (zoom) in the above PTZ. A dome camera can set multiple points, and the dome camera can switch points through its own PTZ. It should be noted that a point of the dome camera represents a shooting field of view. Therefore, switching the point of the dome camera is equivalent to adjusting the shooting field of the dome camera.

The dome camera is widely used in the monitoring of open areas. The cruise setting of the dome camera is usually: setting multiple points for the dome camera and the cruise time period corresponding to each point, wherein each point corresponds to a scene, and multiple Points are bound to the same service (for example, face detection), so that the dome camera can perform the same service by time and by point to complete the cruise task. For example, in a certain park, three points are set for the ball machine, namely: point 1, the entrance of the park; point 2, the road in the park; point 3, the edge of the park wall. In addition, set the cruise time period corresponding to point 1 from 8:00AM to 9:30AM, the time period corresponding to point 2 from 10:00AM to 17:00PM, and the time period corresponding to point 3 from 19:00PM to 22: 00PM, and the three points are respectively bound to the face detection service. After the setting is completed, the dome camera will sequentially collect images at the three points set above according to the set schedule and perform face detection on the images. Inspection business.

However, if the user needs: perform both face detection and vehicle detection at point 1 (the entrance of the park), perform face detection at point 2 (the road in the park), and execute the human at point 3 (the edge of the park wall). For face detection, the time period corresponding to the three points remains unchanged. In this case, two domes need to be deployed. The cruise setting of dome 2 is the same as above, and point 1 (park entrance) is set for dome 2, and the corresponding time period is still from 8:00AM to 9: 30AM and point 1 is bound to the service of vehicle detection to meet user needs.

However, if the user needs are: face detection at point 1 (entrance of the park) (8:00AM to 9:30AM), and illegal parking detection at point 2 (road in the park) (10:00AM to 17:00AM) 00PM), perform intrusion detection (19:00PM to 22:00PM) at point 3 (the edge of the campus wall). In this case, 3 domes need to be deployed. Dome 1 is used for face detection at point 1, dome 2 is responsible for illegal parking detection at point 2, and dome 3 is used for face detection at point 2. Responsible for intrusion detection at point 3 to meet user needs. It can be seen from this that when there are multiple business requirements in a certain scenario or different business requirements in different scenarios, it is necessary to increase the number of deployed domes to meet user needs. Although the number of domes used increases, the utilization rate of each dome is low, which not only increases hardware cost, but also wastes resources.

In view of the above-mentioned existing problems, the embodiments of the present application provide a dome camera cruise method, which can realize the use of as few domes as possible to meet various business requirements in the same scenario or different business requirements in different scenarios, which not only saves hardware costs, but also saves hardware costs.

In some possible embodiments, if the scene parameter information also includes the priority information corresponding to the scene, when the next scene exists, if the priority corresponding to the previous scene (in the case of the previous scene) is detection First, in this case, if a target object is detected in the scene image corresponding to the previous scene, the camera can delay switching to the next scene until the detection task of the previous scene ends.

In a specific implementation, a scene management module, a cruise module and a business module are deployed in the camera, wherein the scene management module is used to receive a scene switch request sent by the cruise module and determine whether to perform a scene switch currently. When it is determined to perform a scene switch, the scene The management module is used to instruct the service module to close the service corresponding to the previous scene (if the previous scene exists) and to open the service corresponding to the next scene, and the scene management module is also used to send the point corresponding to the next scene to the cruise module . The cruise module is used to determine whether the current moment is the scene switching moment according to the cruise time information of the scene, and when it is determined that the current moment is the scene switching moment, it sends a scene switching request to the scene management module to obtain the point corresponding to the next scene. It is also used to adjust its own camera device to the point corresponding to the next scene after receiving the point corresponding to the next scene sent by the scene management module.

No specific limitation is made.

In the following, the camera may take the ball camera as an example to illustrate the solution, but the embodiment of the present application does not limit the camera to be only the ball camera.

It should be noted that, before the dome camera performs the cruise task, the dome camera needs to be configured for the cruise task, so that each scene in the cruise path is bound to a shooting field of view and at least one business, where the scene is jointly determined by the shooting field of view and the business. It is decided that the services bound to different scenarios can be different, so that as few domes as possible can meet different business requirements in the same scenario or different business requirements in different scenarios. Referring to FIG. 2, FIG. 2 is a flowchart of a method for configuring a cruise control of a ball aircraft provided by an embodiment of the present application. The method includes but is not limited to the following steps:

After the scene configuration is completed, scene parameter information can be obtained, where the scene parameter information includes the identifier of each scene in the multiple scenes to be cruised, the point corresponding to each scene, and the service identifier corresponding to each scene. It should be noted that the scene is jointly determined by the point and the business. For any two scenarios, if and only if the points corresponding to the two scenarios are the same and the services corresponding to the two scenarios are also the same, then the two scenarios for the same scene. If the points corresponding to the two scenarios are different or the services corresponding to the two scenarios are different, the two scenarios are different scenarios.

Among them, the point position represents the shooting angle of the dome camera (or called the shooting field of view), and setting the point position of the dome camera refers to setting the PTZ coordinates of the dome camera, that is, the horizontal angle, pitch angle and focal length of the dome camera. The range can be [0, 2π], and the range of the pitch angle can be (-π, 0). The focal length determines the imaging size, field angle, depth of field, etc. of the subject captured by the lens, and the shorter the focal length, the better the imaging. Smaller, the larger the field of view, the longer the depth of field. In some possible embodiments, the point position further includes an aperture value, a zoom value, and the like.

A service represents an algorithm or program for detecting objects or object events in a surveillance environment, such as recognizing objects in images, or recognizing object events in images. Among them, the target body can be a person, a face, a vehicle, etc., and the target event can be a vehicle parking illegally, a vehicle speeding, a vehicle running a red light, a person stealing a car, a vehicle collision, a pedestrian fighting, a pedestrian fainting, a pedestrian intrusion, etc. For example, the business can be face detection, face recognition, vehicle detection, illegal parking detection, speeding detection, intrusion detection, non-human detection, red light running detection, vehicle collision detection, pedestrian fainting detection, car theft detection, etc. No specific limitation is made. Service parameters can be set for the service, for example, preset detection frame size, snapshot mode, image brightness compensation coefficient, etc. Taking the service bound to a scene as face detection as an example, you can set the service parameters of the service in the scene, such as the preset detection frame size, snapshot mode, face sensitivity, and face brightness compensation coefficient. Taking the preset detection frame size as an example, when performing face detection processing on the scene image collected by the dome camera at this point, when the size of the detected face frame is smaller than the above-mentioned preset detection frame size, the person The face frame is not used as a detected face. It should be noted that the service parameters of different services may be different. For example, the preset detection frame size of face detection may be set to 20*20, and the preset detection frame size of vehicle detection may be set to 30*30. It can be seen that by binding multiple services to a certain scenario and configuring the service parameters of the multiple services respectively, the configuration separation of different services in different scenarios can be realized.

In some possible embodiments, the same service may also have different service parameters in different scenarios. Take face detection as an example. Suppose the dome camera is installed in the park, scene 1 corresponds to a road in the park, and scene 2 corresponds to the square outside the park. If scene 1 and scene 2 are both bound to the face detection service, Since the distance from the square outside the park to the dome camera is greater than the distance from the road in the park to the dome camera, the size of the preset detection frame corresponding to the face detection service in scenario 2 is smaller than the preset detection frame corresponding to the face detection service in scenario 1 size, thus realizing the configuration separation of the same service in different scenarios.

In some possible embodiments, in addition to binding one point and at least one service for each scenario, the so-called scenario configuration for each scenario also includes setting the priority of the service corresponding to each of the above scenarios, wherein the priority Including detection priority and non-detection priority, the priority can be used to determine whether the dome camera meets the scene switching conditions. Specifically, if the dome camera has the next scene, and the priority of the service corresponding to the previous scene is "non-detection priority", the dome camera satisfies the scene switching condition; if the dome camera has the next scene, the service corresponding to the previous scene The priority of the dome camera is "Detection Priority" and the target object is detected in the scene image corresponding to the previous scene, the dome camera does not meet the scene switching conditions; if the dome camera has the next scene, the priority of the service corresponding to the previous scene is "Detection priority" and no target is detected in the scene image corresponding to the previous scene, the dome camera meets the scene switching conditions.

It should be noted that the user interface may be provided by the server. In a specific implementation, the user interface can be a configuration interface generated by the server in response to the operation of the user accessing the configuration URL of the dome machine. In this case, the user interface of the server is the configuration webpage of the dome camera. In another specific implementation, the user interface can also be a configuration interface provided by a client installed in the server for ball machine configuration. Specifically, the client used for ball machine configuration is installed in the server, and the user clicks the client. , in this case, the user interface of the server is the configuration interface provided by the client.

For example, the user interface may be the interface shown in FIG. 3 . It should be noted that the interface shown in FIG. 3 may also be called a scene configuration interface. FIG. 3 is only an example of a scene configuration interface, and does not limit the scene of the present application. The configuration interface is only as shown in FIG. 3 , and the scene configuration interface may be any interface that implements the above-mentioned scene configuration function. As shown in Figure 3, Figure 3 is the dome camera ID-scene configuration interface, where ID represents the dome camera's identification, and multiple functional modules are listed on the interface, such as point binding module, business binding module, Add a scene module and a monitoring perspective module. Among them, the point binding module is used for point setting, and the point binding module lists the input boxes of the horizontal angle, the pitch angle and the focal length in turn. In some possible embodiments, an input box of aperture can also be added in the point binding module; the business binding module is used for business setting, and the business binding module lists "face detection 1", "vehicle detection 2" " and other business options, take "Face Detection 1" as an example, "1" is the identity of face detection, which uniquely represents face detection, in addition, you can also set business parameters, such as the preset detection frame size; The monitoring angle module is used to display the scene images currently collected at the points set on the interface, which can assist the user to set the scene point binding. A scene module has been added to display the relevant parameters of the currently set scene. For example, the added scene module in Figure 3 shows "scene 1: point (40°, -40°, 50), face recognition 3 and vehicle detection 2, detection priority". On the interface shown in Figure 3, there is also an "Add" button. After completing the settings corresponding to the above point binding module, business binding module and priority setting module, click the "Add" button to add the currently set The relevant configuration of the scene is added to the added scene module above.

Optionally, a priority setting module may also be set on the interface shown in FIG. 3 , and the priority setting module is used to set a priority for the service selected in the service binding module. It can be understood that in the interface shown in FIG. 3 , the service binding module is separated from the priority setting module, so that when multiple services are selected in the service binding module, if the selected multiple services are preferentially set, they will be selected by the priority setting module. Multiple selected services have the same priority setting, for example, the same as "Detection Priority" or "Non-Detection Priority". In some possible embodiments, the priority setting module can also be set in the service binding module (not shown in FIG. 3 ), so that multiple services selected in the service binding module can be set with priority respectively, so that different Businesses can have different priority settings. It should be noted that when the priority is set to "detection priority", it is necessary to consider whether a target is detected in the currently collected scene image when judging whether the scene switching condition is satisfied.

Specifically, the user configures the scene 2 on the user interface shown in FIG. 3. In the point binding module, the user can input the horizontal angle, pitch angle and focal length of the point through the keyboard. For example, the scene 2 corresponds to The point position is "horizontal angle 60°, pitch angle -30°, focal length 85mm". In a specific implementation, a progress bar (not shown in Figure 3) can also be set next to the horizontal angle, the pitch angle and the focal length in the point binding module, and the horizontal angle, the pitch angle and the focal length can be set respectively by dragging the corresponding progress bar. , and the value corresponding to the current position is displayed next to the progress bar. In another specific implementation, the point binding module can also be provided with two adjustment keys, namely a "+" key and a "-" key, which can be used to adjust the horizontal angle, the pitch angle or the focal length. For example, set the horizontal angle, assuming that the current horizontal angle is 50°, according to the scene image displayed by the monitoring viewing angle module on the right side, it is found that the angle is a little to the left, and the scene image displayed in combination with the monitoring viewing angle module can be increased by clicking the "+" button. Horizontal angle up to a suitable value. In the service binding module, configure the service for scenario 2, check the "face detection 1" service, and set the default detection frame size to 20*20. Optionally, the priority of the service "face detection 1" may also be set. For example, checking "non-detection priority" means that the priority of the corresponding service is set to non-detection priority. To sum up, after completing the point binding, service binding and priority setting (if any) of scene 2, click the "Add" button on the right side, the scene configuration information of scene 2 is stored, and the The added scene module will add a message "Scene 2: Point (60°, -30°, 85), face detection 1, non-detection priority", which means that two scenes have been configured for the dome camera. : Scenario 1 and Scenario 2 respectively. The scene configuration method according to the above-mentioned scene 2 can be used to configure other scenes required by the dome camera, which will not be repeated here.

It should be noted that, for the above scenario configuration process, the embodiments of the present application do not limit the execution order of setting the point corresponding to the scenario, setting the service corresponding to the scenario, and setting the priority of the service corresponding to the scenario.

S102. Perform cruise configuration on each of the multiple scenarios on the user interface.

In the embodiment of the present application, after multiple scenarios are set for the dome camera, it is necessary to perform cruise configuration on each of the multiple scenarios on the user interface. The so-called cruise configuration for each scenario refers to: for each scenario The scene sets the cruise time period. In some possible embodiments, when there are multiple scenarios corresponding to the same cruise time period, in this case, the monitoring duration corresponding to each scenario can also be set. For the relevant description of the user interface, reference may be made to the relevant description of S101 , which will not be repeated here.

Among them, the cruise time period indicates the working time period of the dome camera, and the cruise time period of the scene indicates that the scene is valid during the cruise period. For example, assuming that the cruise time period of scene 1 is only 8:00AM to 10:00AM, it means that scene 1 is monitored during the time period from 8:00AM to 10:00AM, specifically from 8:00AM to 10:00AM The intra-segment dome camera can collect scene images at the points corresponding to scene 1 and perform services corresponding to scene 1 on the scene images. The monitoring time corresponding to the scene refers to the duration or stay time of the dome camera in the scene each time, and it also means the time the dome camera continuously monitors the scene each time. For example, if there are two scenarios corresponding to the cruise period from 8:00AM to 9:00AM, namely scenario 1 and scenario 2, and setting the monitoring duration of scenario 1 to 30 minutes and the monitoring duration of scenario 2 to 30 minutes, it means that, From 8:00AM to 9:00AM, you can monitor scene 1 from 8:00AM-8:30AM and monitor scene 2 from 8:31AM-9:00AM, or monitor scene 2 from 8:00AM-8:30AM and monitor scene 2 from 8:00AM to 8:30AM. 8:31AM-9:00AM Monitoring Scenario 1, which is not specifically limited in this application.

In a specific implementation, when there are multiple scenes in a certain cruise time period, the cruise sequence of each scene in the cruise time period can also be set, so that the dome camera can cruise according to the cruise time of each scene during the cruise time period. Sequentially take turns cruising. For example, if there are scene 1 and scene 2 between 8:00AM and 9:00AM, the monitoring duration of scene 1 is 30 minutes and the monitoring duration of scene 2 is 30 minutes, and the cruise sequence of scene 1 is 1 and the cruise sequence of scene 2 is 2. From 8:00AM to 9:00AM, monitor scene 1 from 8:00AM-8:30AM first, and monitor scene 2 from 8:31AM-9:00AM later.

In a specific implementation, when there are multiple scenes within a certain cruise time period, the monitoring duration of each scene in the multiple scenes determines the number of alternate cruises of each scene within the cruise period. For example, if Scenario 1 and Scenario 2 are set between 8:00AM and 9:00AM, and the monitoring duration of Scenario 1 is 30 minutes and the monitoring duration of Scenario 2 is 30 minutes, then from 8:00AM to 9:00AM, the scenarios can be monitored separately. 1 once and scene 2 once. If Scenario 1 and Scenario 2 are set from 8:00AM to 9:00AM, and the monitoring duration of Scenario 1 is 15min and the monitoring duration of Scenario 2 is 15min, then from 8:00AM to 9:00AM, Scenario 1 can be monitored separately Twice and Scenario 2 twice, if the cruise sequence of Scenario 1 is set as the first and the cruise sequence of Scenario 2 as the second, the cruise process from 8:00AM to 9:00AM is as follows: Scenario 1 (8:00AM to 8 :15AM) - Scene 2 (8:15AM to 8:30AM) - Scene 1 (8:30AM to 8:45AM) - Scene 2 (8:45AM to 9:00AM), that is to monitor scene 1 and scene 2 twice in turn .

It can be seen from this that after setting the cruise time period and the monitoring duration corresponding to each scene in the multiple scenarios corresponding to the cruise time period, the scene corresponding to the cruise time period can be determined from the cruise time period and the monitoring duration of the scene. switch time. For example, if the cruise process from 8:00AM to 9:00AM is: scene 1 (15min) - scene 2 (15min) - scene 1 (15min) - scene 2 (15min), then the scene corresponding to 8:00AM to 9:00AM There are four switching times, namely 8:00AM, 8:15AM, 8:30AM and 8:45AM. When a certain cruise period corresponds to only one scene, the start moment of the cruise period is a scene switching moment of the scene.

In some possible embodiments, after the cruise time period and the monitoring duration of each scene in the cruise time period are set, the cruise time period is automatically divided into multiple time periods, which improves the configuration efficiency of the dome camera. It may be assumed that multiple time periods include a first time period and a second time period, where the first time period is set to be bound to the first shooting field of view (or the first point) and the first business, and the second time period is set. Binding with the second shooting field of view (or called the second point) and the second business. It should be noted that after the configuration is completed, the server sends configuration information to the dome camera, and the configuration information includes a first mapping relationship and a second mapping relationship, wherein the first mapping relationship is the first time period, the identifier of the first service, and the first mapping relationship. A mapping relationship between the shooting fields of view, and the second mapping relationship is a mapping relationship between the second time period, the identifier of the second service, and the second shooting field of view. It should be noted that since the shooting field of view and the business jointly determine the scene, the first mapping relationship is equivalent to representing the scene corresponding to the first time period and the first time period, and the second mapping relationship is equivalent to representing the second time period and the second time period. The scene corresponding to the time period. In this way, the ball machine can be located at different points at different times to execute different services or at different times at the same point to execute different services.

It can be understood that the first time period is the monitoring duration of the scene determined by the first shooting field of view and the first service, and the second time period is the monitoring time period of the scene determined by the second shooting field of view and the second service. When the sum of the length of the first time period and the length of the second time period is less than the length of the cruising time period, the above-mentioned multiple time periods further include: alternately executing the first time period and the length of the second time period with the first time period. The first time period and the second time period correspond to the time period of the service.

For example, assuming that the cruise time period is set to be 9:00AM-10:00AM, the cruise time period corresponds to scene 1 and scene 2. The cruise sequence of scene 1 is prior to the cruise sequence of scene 2, and the monitoring time of scene 1 is 10 minutes. The monitoring duration of 2 is 20 minutes. Scenario 1 is bound to point 1, business 1 and business 2, and scene 2 is bound to point 2 and business 3. As can be seen from Table 1, after completing the above configuration, the cruise time period 9:00AM-10:00AM is automatically divided into four time periods, namely 9:00AM-9:10AM monitoring scene 1, 9:10AM-9 :30AM monitoring scenario 2, 9:30AM-9:40AM monitoring scenario 1, 9:40AM-10:00AM monitoring scenario 2, in this case, for example, 9:00AM-9:10AM can be the first time period, 9 :10AM-9:30AM or 9:40AM-10:00AM may be the second time period. For another example, the first time period may be 9:30AM-9:40AM, and the second time period may be 9:40AM-10:00AM.

Table 1

In some possible embodiments, the cruising configuration for each scene may also be: first setting a certain cruising time period, and then adding each set scene to each cruising time period as needed. When multiple scenes are added within a certain cruise time period, the monitoring duration of each scene within the cruise period can also be set in turn.

For example, referring to FIG. 4A, FIG. 4A is an example of a cruise configuration interface provided by the present application. The interface lists a cruise time period module, a scene identification module, a cruise path module, etc., wherein the cruise time period module includes a time scale bar and a sliding bar, the length of the sliding bar can be adjusted, and a cruise time period can be set by dragging the sliding bar; the scene identification module displays the currently created scenes, and also lists the input boxes for the monitoring duration of each scene and the The input box of the cruise sequence corresponding to the scene, the scene identification module allows the user to select the scene to be added to the cruise time period set in the cruise time period module and the monitoring duration corresponding to the set scene; the cruise path module is used to display the current The mapping relationship between the set cruise time period and the added scene can also be displayed, and the monitoring duration and cruise sequence corresponding to the scene can also be displayed. On the interface shown in Figure 4A, there is also a "Save" button. After completing the settings corresponding to the cruise time period module and the scene identification module, click the "Save" button to save the currently set cruise period and the selected scene. The mapping relationship between them is added to the above cruise path module.

As shown in Figure 4A, a cruise time period can be set first on this interface, for example, drag the slider to select the cruise time period of 9:00AM-10:00AM, and then select the cruise time period from the created scene For the corresponding scenario, for example, scenario 1 and scenario 2 in the created scenario shown in FIG. 4A are checked, and the monitoring duration of scenario 1 is set to 10 minutes and the monitoring duration of scenario 2 is set to 20 minutes. In some possible embodiments, when multiple scenes are set in the same cruise time period, the cruise sequence of each scene in the cruise time period can also be set. For example, in FIG. 4A, the scene 1 is set at 9:00AM-10: The cruise order within 00AM is 1 and the cruise order of scene 2 within 9:00AM-10:00AM is 2. After completing the cruise configuration in the cruise time period of 9:00AM-10:00AM, click the "Save" button, the cruise path module in Figure 4A will add a record such as "cruise time period 9:00AM-10:00AM, Scenario 1 (monitoring duration 10min cruise sequence 1), scenario 2 (monitoring duration 20min cruise sequence 2)", from which you can clearly see the cruise time period corresponding to each scene, the monitoring duration corresponding to each scene, and where each scene is located. Corresponds to the cruise sequence in the cruise time period. The cruise configuration can be performed on other scenarios in the cruise path according to the above method, and details are not described herein again.

It should be noted that the interface shown in FIG. 4A can be used to set the cruise time period of each day of the dome camera. In some possible embodiments, a date may also be added on the interface shown in FIG. 4A to implement cruise configuration of the dome camera in units of weeks. It should be noted that the daily cruise configuration of the ball machine may be the same or different, which is not specifically limited in the embodiment of the present application.

Referring to Fig. 4B, Fig. 4B is an example of another cruise configuration interface provided by this application, Fig. 4B is a ball machine ID-cruise configuration interface, ID represents the identification of the ball machine, and the interface is listed with scene identification input box, cruise time Segment module, monitoring duration input box, cruise path module, etc. Among them, there is a drop-down box under the scene ID input box, and the drop-down box lists the currently created scenes, and the user can select a scene from the drop-down box each time for cruise time After the user selects a scenario, the monitoring duration corresponding to the scenario can be set in the monitoring duration input box. In some possible embodiments, the interface shown in FIG. 4B may also add an input box for a cruise sequence, so that the user can set the cruise sequence of the corresponding scene in the cruise time period. The cruise time period module includes a time scale bar and a slide bar. The length of the slide bar can be adjusted. A cruise time period can be set by dragging the slide bar; the cruise path module is used to display the time between the set scene and the cruise time period. It can also display the monitoring duration and cruise sequence corresponding to the scene. On the interface shown in Figure 4B, there is also a "Save" button. After completing the settings of the cruise time period module, scene identification, monitoring duration, etc., click the "Save" button to save the current selected scene and the set cruise period. The mapping relationship between them is added to the above cruise path module.

As shown in FIG. 4B , you can select a scene to be set on the interface, for example, scene 3, and drag the slider to set the cruise time period corresponding to scene 3. For example, drag the slider to occupy the time between 14:00 and 18:00. Time period, and set the monitoring duration of scene 3 to 20min, and finally click the "Save" button, thus completing the cruise configuration for scene 3. After clicking the "Save" button, the cruise path module in Figure 4B will add a new A message saying "The scene ID is 3, the cruise time period is 14:00PM-18:00PM, and the monitoring time is 20min". In some possible embodiments, the setting of the cruise time period on the interface shown in FIG. 4B can not only be set by dragging the slider, but also a preset time period may be input through the keyboard, which is not specifically limited in this application. It should be noted that, on the interface shown in FIG. 4B , the cruise sequence of a certain scene in the corresponding cruise time period can also be set. For example, in FIG. 4B , it can be seen that both scene 1 and scene 2 that have been set in the cruise path correspond to the cruise time period from 9:00AM to 10:00AM, and within the cruise time period, the cruise sequence of scene 1 is 1, and the cruise sequence of scene 2 is 2, that is, scene 1 is monitored first and then scene 2 is monitored.

It should be noted that FIG. 4A or FIG. 4B is only an example of a cruise configuration interface, but the present application does not limit the cruise configuration interface to the one shown in FIG. 4A or FIG. 4B , which can be any one of the above cruise configuration functions. User Interface.

It should be noted that the interface shown in FIG. 3 and the interface shown in FIG. 4A (or FIG. 4B ) may be two separate and independent interfaces, and the interface shown in FIG. 3 is switched to that shown in FIG. 4A (or FIG. 4B ). The condition of the interface can be after the scene configuration is completed, or it can be derived from the jump key to enter the cruise configuration interface. In some possible embodiments, the interface shown in FIG. 3 and the interface shown in FIG. 4A (or FIG. 4B ) can also be combined into one interface, on which scene configuration can be performed for newly added scenes while scene configuration for existing scenes can be performed on the interface. Add a good scene for cruise configuration. The embodiments of the present application do not specifically limit the display forms of the interface shown in FIG. 3 and the interface shown in FIG. 4A (or FIG. 4B ).

It should be noted that this application does not specifically limit the execution order of S101 and S102, that is to say, the scene configuration (S101) may be performed first and then the cruise configuration (S102) may be performed, or the cruise configuration (S102) may be performed first and then the cruise configuration (S102). The scene configuration ( S101 ), the scene configuration ( S101 ) and the cruise configuration ( S102 ) can also be performed at the same time.

It should be noted that, after the configuration of the above S101 and S102 is completed, the server sends the related configuration information of the ball machine to the ball machine.

It can be seen that, by implementing the cruise configuration method of the dome camera, binding a point and at least one service to each of the multiple scenarios monitored by the dome camera, and setting a cruise time period for each scene, etc. Use as few domes as possible to meet different business needs in the same scenario or different business needs in different scenarios, and improve the utilization rate of a single dome.

After completing the cruise task configuration of the dome camera by the method described in the above-mentioned embodiment of FIG. 2, the dome camera can execute the preset cruise task based on the stored relevant configuration information, so as to realize the switching of different scenes and the acquisition of scene images. Perform at least one business process.

Referring to FIG. 5, FIG. 5 is a camera method provided by an embodiment of the present application, and the method includes but is not limited to the following steps:

S201. The dome camera detects that the current time is the time to switch to the second scene.

In the embodiment of the present application, the cruise time information includes the identification of each scene in the multiple scenes to be cruised by the dome camera and the cruise time period corresponding to each scene, and the dome camera detects that the current moment is the scene switching moment according to the cruise time information, And the current moment corresponds to the second scene, in addition, the ball camera is located at the first point at the last moment of the current moment. It should be noted that the second scenario is bound to the second point and the second service.

Among them, the second point represents a shooting field of view (or shooting angle) of the dome camera, and the second service can be face detection, face recognition, vehicle detection, illegal parking detection, speeding detection, intrusion detection, and non-human detection. , red light running detection, vehicle collision detection, pedestrian fainting detection, car theft detection, etc.

In some possible embodiments, when a certain cruise time period corresponds to multiple scenarios, the cruise time information further includes the monitoring duration corresponding to each scenario and the cruise sequence corresponding to each scenario. It should be noted that the cruise time information may be pre-stored in the dome machine, or may be acquired by the dome machine from a server, which is not specifically limited in this application. It should be noted that in addition to the cruise time information, the dome camera also stores scene parameter information. The scene parameter information includes the points corresponding to each scene in the multiple scenes to be cruised and the services bound to each scene. Of course, The scene parameter information can also be obtained by the dome camera from the server. In some possible embodiments, the cruise time information and the scene parameter information may be two separate pieces of information or a combined piece of information, which is not specifically limited in this application.

Among them, the last moment of the current moment can be any moment within the preset time interval before the current moment, and the preset time interval can be 20ms, 50ms, 100ms, 200ms, 350ms, 1s, 4s or other values. For the convenience of description, Hereinafter, the previous moment of the current moment is simply referred to as the previous moment.

For example, the cruise time information can be the cruise schedule shown in Table 2. As shown in Table 2, assuming that the cruise time period on a certain day is only 9:00AM-10:00AM, the cruise time period corresponds to two scenarios, respectively Scenario 1 and Scenario 2, where the monitoring duration corresponding to Scenario 1 is 10 minutes, and the monitoring duration corresponding to Scenario 2 is 20 minutes. You can also set the cruise sequence of Scenario 1 to be the first in the cruise time period of 9:00AM-10:00AM. in the cruise sequence of Scenario 2. See Table 3. Table 3 is an example of scene parameter information. It can be seen from Table 3 that scene 1 is bound to point 1 and service 1, where point 1 represents the shooting field of the dome camera in scene 1; scene 2 is bound Point 2 and business 2, where point 2 represents the shooting field of view of the dome camera in scene 2, and business 1 and business 2 are different. Of course, in some possible embodiments, Table 2 and Table 3 can also be combined into one table. It can be understood that during the cruising time period of 9:00AM-10:00AM, the ball will cruise in turn according to scene 1-scene 2-scene 1-scene 2. In this case, the scene switching times may be 9:00AM, 9:10AM, 9:30AM, and 9:40AM. Take the current moment as 9:00AM as an example, then the scene corresponding to the current moment is scene 1. In this case, the last moment can be 8:59:00AM, 8:59:30AM, etc., which is not specifically limited in this application .

This step will be described with reference to the modules in the camera in the above-mentioned FIG. 1A. The camera is the dome camera. After the dome camera is turned on, the scene management module obtains the cruise time information and scene parameter information from the memory of the dome camera, and will cruise the camera. The time information is sent to the cruise module. Based on the cruise time information, the cruise module in the dome camera detects that the current moment is the scene switching moment and the current moment corresponds to the second scene.

场景2 scene 2	点位2 point 2	业务2 Business 2

It should be noted that each point in Table 3 represents a shooting field of view. Based on the configuration information shown in Tables 2 and 3 above, in this embodiment of the present application, the dome camera performs scene switching at the moment of scene switching. kind:

The first one is that the dome camera detects that the current moment is the moment to switch to scene 2. Scene 2 is determined by point 2 and service 2. The dome camera switches directly at the current moment, that is, adjusts itself to point 2 to collect the second image, and Perform processing corresponding to service 2 on the second image.

Among them, this situation specifically includes situation A and situation B:

Situation A: Although the dome camera was located at point 1 at the last moment, but the dome camera did not start to work (that is, the dome camera did not collect images at point 1 and did not process the images collected at point 1), the dome camera is When it is detected that the current moment is the moment to switch to scene 2, the dome camera will switch directly at the current moment;

Scenario B: The dome camera collected the first image at point 1 at the last moment and processed the first image with service 1, then when the dome camera detects that the current moment is the moment to switch to scene 2, the dome camera is at the current moment switch directly.

Second, the dome camera collected the first image at point 1 at the last moment and processed the first image in service 1. The dome camera detects that the current moment is the moment to switch to scene 2, and scene 2 consists of point 2 and Service 2 is confirmed, but the first image is being collected at the current moment or the first image has not been processed yet. In this case, the dome camera waits for the first image to be processed before performing the switch, that is, adjusts itself to point 2 to collect the second image , and perform processing corresponding to service 2 on the second image.

The third type is that the dome camera collected the first image at point 1 at the last moment and processed the first image in service 1. The dome camera detects that the current moment is the moment to switch to scene 2, but the dome camera has collected the first image at the first moment. The target object or target event is detected in the first image of When the target body and/or target event is detected, the dome camera will perform switching, that is, adjust itself to point 2 to collect a second image, and perform processing corresponding to service 2 on the second image.

It should be noted that the above-mentioned first case A includes the following example in S202-S206 where there is no corresponding scene at the last moment, and the first case B includes the following S202-S206 in the first scene corresponding to the last moment The priority is set to non-detection priority, and the priority of the first scene corresponding to the previous moment is set to detection priority, but no target or target event is detected in the first image. The second method includes the following In S202-S206, the dome machine waits for the first service to be processed before executing the scene switching. An example of a delayed switching scenario caused by a target object or target event detected in . The judging process of the above three scene switching modes is specifically described below through S202-S206:

S202. Determine whether there is a corresponding scene at the last moment.

In the embodiment of the present application, when the dome camera detects that the current moment is the scene switching moment and the current moment corresponds to the second scene, the dome camera also needs to determine whether there is a corresponding scene at the previous moment, and determines that there is no corresponding scene at the previous moment. , it means that the dome machine is at the first point at the last moment, but the dome machine has not started to work, and execute S203; when it is determined that there is a corresponding scene at the last moment, execute S204.

Specifically, it is determined whether the last moment is within any cruise time period in the cruise time information, and if the last moment is not within any cruise time period in the cruise time information, it is determined that there is no corresponding scene at the last moment; If a moment is within a certain cruise time period in the cruise time information, it is determined that there is a corresponding scene at the previous moment.

For example, take the cruise time information shown in Table 2 above as an example to illustrate the process of judging whether there is a corresponding scene at the last moment: in the cruise time period of 9:00AM-10:00AM, it can be seen that the scene switching time can be It is 9:00AM, 9:10AM, 9:30AM and 9:40AM. If the current time is 9:00AM and the last time is 8:59AM, it is easy to know that the last time is not within the only cruise time period of 9:00AM-10:00AM shown in Table 2. The corresponding scene; if the current time is 9:10AM, assuming that the previous time is 9:09AM, since 9:09AM is within the cruise time period of 9:00AM-10:00AM, it is determined that there is a corresponding scene at the previous time. And the last moment corresponds to scene 1.

This step will be described in conjunction with the modules in the camera in the above-mentioned FIG. 1A. When the cruise module detects that the current moment is the scene switching moment based on the cruise time information and the current moment corresponds to the second scene, the cruise module sends a scene switching request to the scene management module. In order to obtain the identifier of the second point and the second service corresponding to the second scene, the scene switching request includes the identifier of the second scene. After the scene management module receives the scene switching request from the cruise module, it judges whether there is a corresponding scene at the last moment in combination with the cruise time information. When it is determined that there is no corresponding scene at the last moment, the scene management module sends the second point to the cruise module. bit and send a first instruction to the service management module, where the first instruction includes the identifier of the second service, and the first instruction is used to instruct the service module to start the second service according to the identifier of the second service. It should be noted that the identifiers of the second point and the second service are found by the scenario management module from the scenario parameter information according to the identifiers of the second scenario. When it is determined that there is a corresponding scene at the last moment, for example, the first scene, the processing procedure of the scene management module may refer to the following description.

S203, start the second service and switch from the first point to the second point to collect the second image.

In the embodiment of the present application, when it is determined that there is no corresponding scene at the last moment, it means that the dome camera is at the first point at the last moment, but the dome camera has not started to work, and the dome camera is determined to perform scene switching at the current moment. operation, that is, starting the second service and switching from the first point to the second point to capture the second image. It can be understood that this example corresponds to the case A in the first manner above.

It should be noted that the identifiers of the second point and the second service may be found by the dome camera from the scene parameter information according to the identifier of the second scene, and the scene parameter information may be pre-stored in the dome camera.

For example, taking the above Table 2 and Table 3 as examples, if the current time is 9:00AM (scene switching time), the current time corresponds to Scene 1, and it is easy to know that there is no corresponding time at the previous time according to the cruise time information shown in Table 2. Scenario, in this case, the dome camera determines to switch the scene at the current moment. According to Table 3, the dome camera can know that scene 1 corresponds to point 1 and service 1. In this case, the dome camera starts service 1 and switches its own point Adjust to point 1 to collect the first image, and within the monitoring duration corresponding to scene 1, that is, 9:00AM-9:10AM, the dome camera will process the first image collected at point 1 for service 1.

It should be noted that, in the case where the second service includes multiple services, after the second image is collected at the second point, the multiple services can be performed on the second image at the same time, or the second image can be sequentially performed on the second image. Each of the multiple services is not specifically limited in this application. For example, if 9:00AM-9:10AM corresponds to scene 1, assuming that scene 1 is bound to point 1, service 1 and service 2, after the scene image is collected on point 1, the scene image can be used for services at the same time The detection corresponding to 1 and the detection corresponding to service 2 can also be performed on the scene image first, and then the detection corresponding to service 2 can be performed. : 05AM-9:10AM for the detection of service 1.

This step will be described in conjunction with each module in the camera in FIG. 1A , the service module receives the first instruction sent by the scene management module, the first instruction includes the identifier of the second service, and the cruise module receives the second point sent by the scene management module. bit, the service module starts the second service according to the identifier of the second service in the first instruction, and the cruise module switches the dome camera from the first point at the last moment to the second point.

It should be noted that, for the time delay of the ball camera switching from the second point to the first point, the embodiment of the present application can be ignored.

S204. When the last moment corresponds to the first scene, close the first service, start the second service, and switch from the first point to the second point to collect the second image.

In the embodiment of the present application, if the last moment corresponds to the first scene, and the first scene is bound to the first point and the first service, in this case, the first service is closed, the second service is activated, and the slave The first point is switched to the second point to capture the second image.

It should be noted that, for the process of enabling the second service and switching to the second point, the ball machine may refer to the above-mentioned description of S203 for details.

It should be noted that, the embodiment of the present application does not specifically limit the execution order of the three of closing the first service, starting the second service, and switching from the first point to the second point. For example, it can be executed one by one. , can also be executed simultaneously.

For example, taking the above Tables 2 and 3 as examples, if the current time is 9:10AM (scene switching time), it can be seen from Table 2 that the current time corresponds to Scene 2, assuming the previous time (for example, 9:09AM), according to Table 2 Knowing that the last moment corresponds to scene 1 and that scene 1 is bound to point 1 and service 1, the dome camera determines to switch the scene at the current moment, and the dome camera knows that scene 2 corresponds to point 2 and service 2 according to Table 2 and Table 3. The machine can turn off service 1, then turn on service 2, and adjust itself from point 1 to point 2 to collect a good image of the scene.

In some possible embodiments, if the last moment corresponds to the first scene, the first scene is bound to the first point and the first service, the dome camera detects that the current moment is the moment to switch to the second scene, and the second The scene corresponds to the second point and the second service, but at the current moment the first image is being collected or the first service is being performed on the first image. In this case, the dome camera waits for the first image to finish processing before The first service is turned off, the second service is started, and the second image is collected by switching from the first point to the second point. It can be understood that this example corresponds to the second manner described above.

This step will be described in conjunction with each module in the camera in FIG. 1A . The scene management module determines that the last moment corresponds to the first scene, and the scene management module determines that the first scene is bound to the first service and the first point based on the scene parameter information. Therefore, the second instruction is sent to the service module. The second instruction includes the identifier of the first service. The second instruction is used to instruct the service module to close the first service. In addition, the scene management module also sends the first point to the cruise module and sends it to the cruise module. The service module sends a first instruction, where the first instruction includes an identifier of the second service, and the first instruction is used to instruct the service module to start the second service. Correspondingly, after receiving the second instruction, the service module closes the first service according to the second instruction, and after receiving the first instruction, starts the second service according to the first instruction, and switches the dome camera from the first The point is switched to the second point.

It should be noted that, the delay caused by the time-consuming start or shutdown of the service is ignored in this embodiment of the present application.

S205. When the priority corresponding to the first scene is detection priority, determine whether a target object or a target event is detected in the first image.

Optionally, in some possible embodiments, the scenario parameter information also includes a priority corresponding to each scenario, the priority includes a detection priority and a non-detection priority, and the priority corresponding to each scenario represents the service corresponding to each scenario. priority. In this case, when the dome camera determines that the last moment corresponds to the first scene, it also needs to determine whether the priority corresponding to the first scene is detection priority, and if it is determined that the priority corresponding to the first scene is detection priority , since the first scene is bound to the first point and the first service, it is also necessary to determine whether the target object or target event is detected after the first service is performed on the first image. Collected at a point. It should be noted that if the first service is used to detect the target body, it only needs to judge whether the target body is detected in the second image; if the first service is used to detect the target event, it only needs to judge whether the target body is detected in the first image. The target event is detected; if the first service is used to detect the target body and the target event, it is necessary to determine whether the target body or the target event is detected in the first image. To sum up, if the dome camera does not detect the target body or the target event or the target body and the target event in the first image, execute the above S204; if the dome camera detects the target body or the target in the first image event, execute S206.

Taking the target body not detected in the first image as an example, the so-called ball camera does not detect the target body in the first image, including the following situations: (1) The first image only includes a single frame image, and the single frame image is executed. The first service is used for detection processing, and the target body is not detected; (2) the first image includes multiple frames of images, and the first service is performed on each frame of the multiple frames of images. A target body is detected; (3) the first image includes multiple frames of images, the first service is performed on each frame of the multiple frames of images, and no target body is detected in each of the multiple frames of images. Similarly, for the target event not detected in the first image, or the target object and target event not detected in the first image, reference may be made to the above description about the target object not detected in the first image.

Among them, the target body and the target event correspond to the business. For example, if the business is face detection, the target body is a face; if the business is vehicle detection, the target body is a vehicle; if the business is machine non-person detection, the target body is motor vehicles, non-motor vehicles and pedestrians; if the business is Vehicle illegal parking detection, the target event is vehicle illegal parking; if the business is vehicle collision detection, the target event is vehicle collision. If the business includes face detection and vehicle detection, the target body includes faces and vehicles. In some possible embodiments, if the services are illegal parking detection and face detection, the target body is a human face and the target event is a vehicle illegal parking. For the description of the target body and the target event, reference may be made to the relevant description in S101 , which will not be repeated here.

In some possible embodiments, when the ball machine detects that the current moment is the moment to switch to the second scene, and the second scene is bound to the second point and the second service, if the previous moment corresponds to the first scene, The first scenario is bound to the first point and the first service. If the priority of the first service is non-detection priority, the above S204 is executed, that is, the first service is turned off, the second service is started, and the switch from the first point to the first service is performed. A second image is acquired at the second point. It can be understood that this example corresponds to the case B in the first manner above.

It should be noted that when a scenario is bound to multiple services, the priority settings of these multiple services can be the same, and the priority corresponding to the scenario is either detection priority or non-detection priority. . In some possible embodiments, when a certain scenario is bound to multiple services, the priority settings of the multiple services may also be different, and the priorities corresponding to the scenario include detection priority and non-detection priority. In this case, the above-mentioned condition of determining that the priority corresponding to the first scene is detection priority refers to determining that the priority corresponding to the first scene has detection priority.

S206. Delay closing the first service and delay switching to the second scenario.

Optionally, in this embodiment of the present application, when the dome camera determines that the last moment corresponds to the first scene and the priority corresponding to the first scene is detection priority, the first scene is bound to the first point and the first service. If a target object or a target event is detected in the first image collected at the first point, the first service is delayed and the first service is delayed and switched to the second scene, where the delayed switch to the second scene refers to delayed startup The second service and delay are switched from the first point to the second point to capture the second image. In a specific implementation, the closing of the first service may be delayed until no target body and/or target event is detected in the first image again collected by the dome camera at the first point. It can be understood that this example corresponds to the third manner described above.

It should be noted that since the first service is delayed and closed, the moment when the dome camera switches to the second scene will also be delayed. If the current time reaches the stop time of a certain cruise time period and there is no corresponding scene at the current time, the running service of the dome camera will be closed, and the dome camera will stop working until the start time of the next cruise time period.

For example, referring to Table 4, Table 4 adds "priority" setting information on the basis of Table 3. It can be seen from Table 4 that the priority of service 1 is "detection priority", and the priority of service 2 is "non-detection priority" . S205 and S206 are further described in conjunction with Table 2 and Table 4. If the current moment is the moment of switching to scene 2 at 9:10AM (scene switching moment), the previous moment (for example, 9:09AM) corresponding to scene 1 is detected, according to the table 4 Obtain the priority corresponding to scene 1 as detection priority, assuming that business 1 is face detection, that is, the target body is a face:

In this case, in a specific implementation, the dome camera checks whether a face is detected in the first image collected at point 1 at the nearest time from 9:10AM to the current time. If the dome camera detects a face in the first image Face, in this case, the dome camera will not close service 1 for the time being, and the dome camera will continue to collect the first image at point 1 and perform face detection on the first image, assuming that the first image collected until 9:12AM In other words, from 9:10AM to 9:12AM, the dome camera has been located at point 1 to collect the first image, and the face detection is performed on the first image and the detection results are all detections. To the face, but no face is detected in the first image collected at point 1 at 9:12AM, the dome can close service 1 at 9:12AM, start service 2, and remove the dome from the point. 1 is adjusted to point 2, that is to say, the dome camera is delayed until 9:12AM to switch from scene 1 to scene 2;

In another specific implementation, the dome camera checks whether a human face is detected in the first image collected at point 1 at the nearest time of 9:10AM from the current time. If no human face is detected in the first image, then The dome camera can perform the scene switching operation at 9:10AM, that is, first close service 1, then open service 2, and adjust itself from point 1 to point 2 to collect the second image.

For another example, in conjunction with Table 2 and Table 4, it can be seen from Table 2 that the cruise time period is 9:00AM-10:00AM, and the sum of the monitoring duration (10min) corresponding to scenario 1 and the monitoring duration (20min) corresponding to scenario 2 is less than The duration (1h) corresponding to the cruise time period 9:00AM-10:00AM, see (1) in Figure 6. Figure 6 (1) shows the time when scene switching occurs without delay within the cruise time period , that is, during 9:00AM-10:00AM, you can take turns cruising scene 1-scene 2-scene 1-scene 2, and the corresponding times are 9:00AM, 9:10AM, 9:30AM and 9:40AM in sequence. When the switching of a certain scene is delayed, the form of subsequent scene switching is mainly implemented in the following two ways:

In a specific implementation, referring to (2) in FIG. 6 , if the moment of switching from scene 1 to scene 2 for the first time is delayed from 9:10AM to 9:12AM, the switching time of other scenes is automatically delayed, that is, the next scene switching The time changes from 9:30AM to 9:32AM. Since the priority corresponding to scene 2 is non-detection priority, it switches to scene 1 at 9:32AM; if there is no delay when switching from scene 1 to scene 2 for the second time, that is If it is 9:42AM, from 9:42AM, the dome camera is located at point 2. Although the monitoring time corresponding to scene 2 is 20min, the stop time of the cruise time period 9:00AM-10:00AM is 10:00AM and 10:00AM. There is no corresponding scene at 00AM, so business 2 is closed at 10:00AM, and the dome camera stops working;

In another specific implementation, referring to (3) of FIG. 6 , if the moment of switching from scene 1 to scene 2 for the first time is delayed from 9:10AM to 9:12AM, if the delay of other scene switching times does not occur, that is, from 9 : Switch to scene 2 from 12AM, stay in scene 2 until 9:30AM, and the first time to switch from scene 2 to scene 1 is still 9:30AM, assuming 9:40AM, due to the priority corresponding to scene 1 For detection priority, if there is no delay when switching from scene 1 to scene 2 for the second time, switch to scene 2 at 9:40AM, because there is no corresponding scene at 10:00AM and 10:00AM is the cruise time period 9:00AM-10: 00AM stop time, so business 2 is closed at 10:00AM, and the dome camera stops working.

Table 4

场景标识Scene ID	点位point	业务 business	优先级priority

场景1scene 1	点位1 point 1	业务1 Business 1	检测优先 detection priority

场景2scene 2	点位2 point 2	业务2 Business 2	非检测优先Non-detection priority

S205 and S206 will be described in conjunction with each module in the camera in FIG. 1A , when the scene management module determines that the first scene corresponds to the last moment, it determines whether the priority corresponding to the first scene is detection priority, if the first scene corresponds to the first scene. When the priority is non-detection priority, you can refer to the relevant description of the above S204, which will not be repeated here; if the priority corresponding to the first scene is detection priority, it is further judged that the first image collected at the first point is in the first image. Whether the target body or target event is detected, if the dome camera does not detect the target body or target event in the first image, you can refer to the relevant description of the above S204, which will not be repeated here; if it is determined that the target is detected in the first image. body or target event, then delay sending the second instruction to the service module, the second instruction is used to instruct the service module to close the first service, and delay sending the first instruction to the service module, the first instruction is used to instruct the service module to open the second service service and delay sending the second point to the cruise module.

In some possible embodiments, the dome camera executes the service corresponding to the scene on the scene image collected at the point corresponding to each scene, and after obtaining the detection result, can also send the detection result to the server for display.

The embodiments of the present application will be described below from another perspective (statically):

After implementing the configuration method described in the embodiment of FIG. 2, the time-division multiplexing of the ball camera can be realized, that is, the ball camera is located at different points at different times to perform different services. In addition, the ball machine can also perform different services at the same point at different times. Specifically, the dome camera collects the first image at the first moment and performs the first service on the first image; the dome camera collects the second image at the second moment and performs the second service on the second image. The second time is different, and the first business and the second business are different. It should be noted that the dome camera is located at the same geographic location at the first moment and the second moment.

Explanation on the first service and the second service: the first service and the second service are both algorithms or programs for detecting target objects or target events in the monitoring environment. The first service includes at least one of the following services: face detection, face recognition, vehicle detection, illegal parking detection, speeding detection, intrusion detection, non-human detection, red light running detection, and driver's irregular driving detection (driver's hands off the steering wheel) , the driver is not wearing a seat belt in the cockpit, etc.), traffic accident detection (vehicle collision, vehicle collision, vehicle collision with public facilities, etc.), pedestrian fainting detection, car theft detection, etc. Similarly, the second service also includes at least one of the above services. It should be noted that the first service is different from the second service. For example, the first service may be face detection, the second service may include face detection and vehicle detection, or the second service may be illegal parking detection.

In some possible embodiments, before the dome camera collects the second image at the second moment, the dome camera needs to adjust its first shooting field of view at the first moment to the second shooting field of view at the second moment, in other words, Before the dome camera collects the second image at the second moment, it can adjust its own shooting field of view.

Among them, the shooting field of view can also be called a point, and the shooting field of view of the dome camera can be adjusted by adjusting one or more of the following parameters of the PTZ of the dome camera: Pan Pan, Tilt Tilt and Zoom Zoom. For the description, reference may be made to the above-mentioned related descriptions, which will not be repeated here.

In some possible embodiments, before the dome camera collects the first image at the first moment, the dome camera pre-receives the binding relationship between the first time period and the first service, and receives the binding relationship between the second time period and the second service in advance. A binding relationship, wherein the first moment belongs to the first time period, and the second moment belongs to the second time period.

It should be noted that the first moment is any moment in the first period of time (including the start moment and the end moment of the first period of time), and the second moment is any moment in the second period of time (including the second period of time). start time and end time). The first time period and the second time period may be two adjacent time periods, or may be two spaced time periods, which are not specifically limited in this application.

For example, it is assumed that 8:00AM-8:20AM is bound with the first shooting field of view and the first service, and 8:30AM-8:40AM is bound with the second shooting field of view, the second shooting field It is understood that 8:00AM-8:20AM is the first time period, and 8:30AM-8:40AM is the second time period. In this case, the first time period and the second time period are the interval two time periods. For another example, it is assumed that 8:00AM-8:10AM is bound with the first shooting field of view and the first service, and 8:10AM-8:30AM is bound with the second shooting field of view and the second service after the configuration shown in Figure 3 above. , it can be understood that 8:00AM-8:10AM is the first time period, and 8:10AM-8:30AM is the second time period. In this case, the first time period and the second time period are two adjacent time periods. a time period. In some possible embodiments, the first time period and the second time period may also be two adjacent time periods within the same cruise time period.

It should be noted that, if it corresponds to the concept of the scene in the above S201-S206, since the scene is jointly determined by the point (or called the shooting field of view) and the business, the first shooting field of view and the first business determine a scene, and the second The shooting field of view and the second service determine a scene. It can be understood that since the first time period corresponds to the first shooting field of view and the first service, and the second time period corresponds to the second shooting field of view and the second service, the scene corresponding to the first time period The scene corresponding to the second time period is different.

In some possible embodiments, the ball machine can also perform different services at the same point in time-sharing. Specifically, the dome camera collects the first image with the first shooting field of view at the first moment, and performs the first service on the first image; the dome camera collects the third image with the first shooting field of view at the second moment, and performs the third image Execute the second service, the first moment is different from the second moment, and the first service and the third service are different. It can be seen from this that the first image and the third image correspond to the same shooting field of view, but the first image and the third image correspond to different services. Because the scene is jointly determined by the shooting field of view and the service, the first time period corresponds to The scene is different from the scene corresponding to the second time period. It realizes that the ball machine performs different services at the same point in time-sharing, improves the utilization rate of the ball machine, and reduces the waste of hardware resources in a complex environment.

In some possible embodiments, the adjustment of the dome camera from the first shooting field of view at the first moment to the second shooting field of view at the second moment may be triggered unconditionally. For example, if the dome camera detects that the current moment is the scene switching time, it enters the step of adjusting the shooting field of view of the dome camera, that is, adjusting at least one of the three parameters of the dome camera's pan/tilt. For details, please refer to the related descriptions of S203 and S204 in the embodiment of FIG. 5 , that is, it is equivalent to switching the dome camera from the second point to the first point. For the sake of brevity of the description, details are not repeated here.

In some possible embodiments, trigger conditions may also be set for the dome camera to adjust its own shooting field of view. Before the dome camera collects the second image at the second moment, the dome camera receives the instruction to adjust the field of view, and the dome camera continues to capture the first image with the first shooting field of view. Vision steps.

For example, taking each module of the camera in FIG. 1A as an example, the scene management module of the dome camera receives the command sent by the cruise module to adjust the field of view at the scene switching time, and the scene management module detects that the first image is currently being captured with the first shooting field of view or The first image collected with the first shooting field of view is in the process of performing business processing. In this case, when the first image is collected or the first image is processed, the dome camera will enter the step of adjusting the shooting field of view. The first shooting field of view at the first moment is adjusted to the second shooting field of view at the second moment, that is, the scene management module sends the relevant parameter information of the second shooting field of view to the cruise module.

For another example, the scene switching module of the dome camera receives the command to adjust the field of view sent by the cruise module at the scene switching moment, and the scene switching module detects that the priority of the first service is detection priority and detects a target or target in the first image. event, in this case, the dome camera continues to collect the first image with the first shooting field of view and executes the first service on the first image until the target object and target event are no longer detected in the collected first image, which is equivalent to the first Once the image collection is completed, the dome camera enters the step of adjusting its own shooting field of view, that is, adjusting the first shooting field of view at the first moment to the second shooting field of view at the second moment.

In some possible embodiments, the identifier of the second service may be obtained by the dome camera from the server. Specifically, before the dome camera collects the second image at the second moment and performs the second service on the second image, the dome camera can also send a switching request to the server, and the switching request can carry an instruction indicating the second time period Correspondingly, the server receives the switching request and searches the pre-stored configuration information from the pre-stored configuration information according to the switching request. The server sends the switching request to the dome camera. In response, the switching request response includes the identification of the second service, or the switching request response includes the identification of the second service and the second shooting field of view, so that the dome camera adjusts according to the second shooting field of view in the switching request response.

In some possible embodiments, the configuration information of the dome machine is pre-stored in the dome machine, and the dome machine itself can directly acquire the identifier of the second service from the memory. Specifically, the dome camera stores a first mapping relationship and a second mapping relationship, wherein the first mapping relationship is the mapping relationship between the first time period and the identifier of the first service, and the second mapping relationship is the second time period and the mapping relationship between the identifier of the second service. In addition, the first mapping relationship further includes a mapping relationship between the first time period and the first shooting field of view, and the second mapping relationship further includes a mapping relationship between the second time period and the second shooting field of view. When the dome camera determines that it needs to adjust the shooting field of view, the dome camera searches for the second shooting field of view corresponding to the second time period and the identification of the second service according to the second time period, and never adjusts its own shooting field of view to the second shooting field of view and according to The identification of the second service activates the second service.

It can be seen that, by implementing the embodiment of the present application, the dome camera realizes switching of different scenarios according to the pre-stored configuration information and performs the business processing corresponding to the scene on the scene image collected at the corresponding point of each scene, in other words, It is realized that the ball machine is located at different points at different times to perform different services, or at the same point at different times to perform different services or perform different services at a certain point, which improves the use efficiency of the ball machine and realizes the best possible use of the ball machine. There may be fewer dome cameras to meet different business needs in different scenarios or multiple business needs in the same scenario, effectively reducing the deployment cost of dome cameras.

Referring to FIG. 7 , FIG. 7 shows yet another imaging method provided by an embodiment of the present application. The difference from the embodiment of FIG. 5 is that the identification of the second service and the second shooting field of view in the imaging method shown in FIG. 7 are obtained by the dome camera from the server, and the embodiment of FIG. 7 requires the dome camera and the server to interact and participate, Whereas in the embodiment of FIG. 5, the identifier of the second service and the second shooting field of view are stored inside the dome camera, the embodiment of FIG. 5 may only be executed by one side of the dome camera. The embodiment in FIG. 7 may be independent of the embodiment in FIG. 5 , or may be a supplement to the embodiment in FIG. 5 . The method includes but is not limited to the following steps:

S301. The dome camera acquires cruise time information.

In the embodiment of the present application, after the dome machine is powered on, the dome machine obtains cruising time information, and the cruising time information includes the identifiers of the multiple scenes the dome machine is to cruise and the cruising time period corresponding to each scene. In some possible embodiments, when a certain cruise time period corresponds to multiple scenarios, the cruise time information further includes the monitoring duration corresponding to each scenario and the cruise sequence corresponding to each scenario. It should be noted that the so-called acquisition of cruising time information can be the cruising time sent by the dome camera receiving the server, or the dome camera fetching pre-stored cruising time information from its own memory.

S302. The dome camera detects that the current time is the time to switch to the second scene, and determines whether the scene switching condition is satisfied at the current time.

In the embodiment of this application, the ball camera is located at the first point at the last moment of the current moment (referred to as the last moment), and the last moment is any moment within the preset time interval before the current moment. For the description, reference may be made to the relevant description in the above S201, and details are not repeated here. The dome camera detects that the current moment is the moment to switch to the second scene based on the cruise time information. In this case, the dome camera needs to determine whether the current moment satisfies the scene switching condition. If the current moment satisfies the scene switching condition, execute S303; If the time does not satisfy the scene switching condition, execute S307.

The scene switching condition can be any of the following:

Condition A: The dome camera was at the first point at the last moment, but the dome camera did not start to work. (that is, there is no corresponding scene at the previous moment).

That is to say, the first moment does not belong to any cruise time period in the cruise time information. Therefore, there is no corresponding scene at the first moment, that is, the dome camera stops working at the first moment.

Condition B: The dome camera collected the first image at the first point at the last moment and processed the first service for the first image, and the priority corresponding to the first service is non-detection priority.

That is to say, the last moment belongs to a certain cruise time period in the cruise time information, and the last moment corresponds to the first scene, and the first scene is bound to the first point and the first service.

Condition C: The dome camera collected the first image at the first point at the last moment and processed the first service for the first image. The priority corresponding to the first service is detection priority, but no target is detected in the first image. body or target event.

That is to say, there is a corresponding scene (ie, the first scene) at the last moment and the priority of the scene is set to detection priority, but no target is detected when the first service is performed on the first image collected at the first point. body or target event. For the description of the service, the target body, and the target event, reference may be made to the relevant descriptions in the above S101 and S205, which will not be repeated here.

It should be noted that the dome camera is judged whether it satisfies any one of the above three conditions (ie, condition A, condition B and condition C). If satisfied, execute S307.

S303, the dome camera sends a scene switching request to the server.

In the embodiment of the present application, when it is determined that the dome camera satisfies the scene switching condition, the dome camera sends a scene switching request to the server to obtain the identifier of the second point and the second service corresponding to the second scene. The scene switching request carries the identifier of the second scene. Correspondingly, the server receives the scene switching request sent by the dome camera.

In some possible embodiments, the scene switching request is further used to obtain the priority corresponding to the second scene from the server. For the description of the priority, reference may be made to the relevant description in the above-mentioned embodiment in FIG. 5 , which will not be repeated here.

S304: The server determines, according to the identifier of the second scenario, the identifier of the second point and the second service corresponding to the second scenario.

In the embodiment of the present application, after receiving the scene switching request sent by the dome camera, the server searches the scene parameter information for the second point corresponding to the second scene and the information of the second service according to the identifier of the second scene in the scene switching request. logo.

The scene parameter information is pre-stored in the server, and the scene parameter information includes a point corresponding to each scene in the multiple scenes to be cruised and a service bound to each scene. In some possible embodiments, the scene parameter information may further include a priority corresponding to each scene. It should be noted that the scene parameter information and the above cruise time information may be included in one piece of information, for example, the cruise configuration information, or may be two separate pieces of information, which are not specifically limited in this application.

It should be noted that the cruise time information and scene parameter information may be automatically stored in the server after the user completes the cruise task configuration of the dome camera on the user interface provided by the server in advance.

S305, the server sends the first information to the ball machine.

In the embodiment of the present application, after obtaining the identifiers of the second point and the second service, the server sends the first information to the dome camera, where the first information includes the identifiers of the second point and the second service. Correspondingly, the ball machine receives the first information sent by the server.

In some possible embodiments, the first information sent by the server to the ball machine further includes the priority corresponding to the second scene. It should be noted that the priority corresponding to the second scenario may be included in the same message together with the identifier of the second point and the second service. For example, the first message may also belong to two messages. This application does not Specific restrictions.

S306, the dome camera performs a scene switching operation.

In the embodiment of the present application, when the dome camera determines that it meets the scene switching conditions at the current moment, after the dome camera receives the first information sent by the server, the dome camera can use the second point in the first information at the current moment. The bit and the identity of the second service perform scene switching.

In a specific implementation, if the dome camera satisfies the condition A in S302, the so-called scene switching performed by the dome camera at the current moment means: starting the second service according to the identifier of the second service, and switching the dome camera from the first point to the second A second image was acquired at two points.

In another specific implementation, if the dome camera satisfies the condition B in S302 or satisfies the condition C in S302, the so-called scene switching performed by the dome camera at the current moment means: closing the first service, starting the second service according to the second service identifier, And, the dome camera switches from the first point to the second point to collect the second image.

S307, the dome camera delays performing S303 until no target body or target event is detected in the first image collected at the first point at the target moment.

In the embodiment of this application, if the dome camera determines that it does not meet the scene switching conditions at the current moment, that is, the dome camera does not meet the three conditions described in S302 at the current moment, it means that the dome camera is at the first point at the current moment. After executing the first service, the dome camera continues to collect the first image at the first point and detects whether the above-mentioned target or target event still exists in the first image. , the dome camera delays sending a scene switching request to the server until the dome camera does not detect a target object or target event in the first image collected at the first point at the target time, where the target time is later than the current time (that is, a certain scene switching time). In other words, if the dome camera no longer detects the target object or the target event in the first image collected at the second point at the target moment, the dome camera sends a scene switching request to the server at the target moment, and accordingly, the dome camera sends a scene switching request to the server at the target moment. The camera also performs scene switching at the target time, that is, the first service is turned off, the second service is activated according to the identifier of the second service, and the dome camera switches from the first point to the second point to collect the second image.

It should be noted that the delay between when the dome camera sends a scene switching request to the server and when the dome camera receives the first information sent by the server is negligible.

The method described in the embodiment of FIG. 7 is described below with reference to each module in the system architecture shown in FIG. 1B : the cruise module in the dome camera obtains the cruise time information from the server, and the cruise module detects the current time based on the cruise time information to switch to the second At the moment of the scene, it is judged whether the current moment satisfies the scene switching condition, that is, whether any one of the conditions described in S302 is met. For details, please refer to the relevant description in S302, which will not be repeated here. When the cruise module determines that the current moment meets the scene switching condition, the cruise module sends a scene switching request to the server, and the scene switching request includes the identifier of the second scene. Correspondingly, after receiving the scene switching request, the scene management module of the server responds to the scene. For a switching request, the scene management module searches the scene parameter information for the second point corresponding to the second scene, the identification of the second service, and the priority of the second service according to the identification of the second scene, and then the scene management module sends a message to the dome camera. The second point, the identifier of the second service, and the priority of the second service. After receiving the identification of the second service sent by the server, the service management module of the ball camera closes the first service (when the service corresponding to the first scene is turned on) and opens the second service. Adjust the position to the second point. If the cruise module determines that the scene switching condition is not met at the current moment, it delays sending a scene switching request to the server until it is determined that no target object or target event is detected in the first image collected at the first point at the target moment.

In the method shown in Figure 7, the process of judging whether the scene switching conditions are met and the business processing process all take place inside the dome camera. When the dome camera determines that it meets the scene switching conditions, it sends a scene switching request to the server to obtain the target scene. The corresponding point, the identifier of the service corresponding to the target scene, and the priority corresponding to the target scene. In some possible embodiments, the judging process of whether the scene switching condition is satisfied may also be performed by the server. Specifically, the dome camera obtains the cruise time information from the server, and based on the cruise time information, it detects that the current time is the moment to switch to the second scene, the dome camera was at the first point at the previous moment, and the dome camera sends the first request to the server, The first request includes the identifier of the second scene. After the server receives the first request, it determines whether the dome camera satisfies the scene switching conditions at the current moment, that is, whether it satisfies any one of the conditions described in S302. For details, please refer to S302. Relevant descriptions are not repeated here. It should be noted that when the dome camera is located at each point, the dome camera will send the scene image collected at each moment at the point and the detection result of the scene image to the server, so the server can be based on the detection result of the scene image. Judging whether a target object or target event is detected in the scene image, if the server determines that the dome camera satisfies the scene switching condition at the current moment, in response to the first request, it sends first information to the dome camera, and the first information includes the corresponding data of the second scene. The second point, the identifier of the second service and the priority of the second service, the dome camera performs scene switching at the current moment according to the received first information. For the specific process of scene switching, please refer to the relevant description of the above S305. Repeat. If the server determines that the dome camera does not meet the scene switching conditions at the current moment, it delays responding to the first request until it is determined that no target object or target event is detected in the first image collected by the dome camera at the first point at the target moment.

It can be seen that, by implementing the embodiment of the present application, the dome camera obtains from the server the identifier of each scene in the multiple scenes to be cruised and the cruise time period corresponding to each scene to switch between different scenes, wherein each scene is associated with one scene. The point is bound to at least one business, so as to meet different business needs in different scenarios or multiple business needs in the same scene with as few domes as possible, improve the use efficiency of domes, and effectively reduce the use of domes. deployment cost.
