Detailed Description
To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
The embodiment of the application provides a monitoring system and a monitoring method, which realize dead-angle-free monitoring through the cooperation of a main camera and one or more auxiliary cameras (or called mirror image cameras) only having video shooting and data transmission functions, and can greatly reduce deployment cost and management cost.
Fig. 1 is a schematic diagram of a monitoring system according to an embodiment of the present application. As shown in fig. 1, the monitoring system provided in this embodiment includes: a main camera 102, an auxiliary camera (e.g., auxiliary cameras 103a and 103b in fig. 1) associated with the main camera 102 and having only video photographing and data transmission functions, and a monitoring server 101. The main camera 102 transmits the shot first video data to the monitoring server 101; the secondary cameras 103a and 103b transmit the photographed second video data to the monitoring server 101 through the primary camera 102. In this example, the main camera 101 is associated with two auxiliary cameras as an example, however, the present application does not limit this. In other implementations, the number of secondary cameras associated with the primary camera may be determined based on actual requirements.
In this example, the primary camera 102 may be a camera having a video shooting function, a data transmission and processing function, which is common at present, while the secondary camera is a camera having only a video shooting and data transmission function. Because the cost of the auxiliary camera is lower than that of the common camera, the auxiliary camera is matched with the main camera for use, and the deployment cost can be greatly reduced.
In this example, the main camera 102 may be connected to the sub cameras 103a and 103b by a wired or wireless manner. For example, the auxiliary cameras 103a and 103b may be connected to the main camera 102 through a network cable; or, a WIFI hotspot may be set on the main camera 102, and the auxiliary cameras 103a and 103b may be connected to the WIFI hotspot provided by the main camera 102, so as to implement communication between the two cameras.
In an exemplary embodiment, as shown in fig. 2, one master camera may include: the system comprises a first transmission module 201, a first shooting module 202 and a configuration management module 203, wherein the configuration management module 203 is connected with the first transmission module 201 and the first shooting module 202, and the first shooting module 202 is connected with the first transmission module 201. The first shooting module 202 may be configured to obtain first video data through shooting, the first transmission module 201 is configured to receive second video data transmitted by the auxiliary camera and send the first video data and the second video data to the monitoring server, and the configuration management module 203 is configured to perform management and configuration work on each part of the main camera. The first video data can be transmitted according to a main code stream or an auxiliary code stream. The main code stream may adopt a coding format with a first definition, and the auxiliary code stream may adopt a coding format with a second definition, wherein the first definition is higher than the second definition.
As shown in fig. 3, one secondary camera may include: the second transmission module 301 is connected with the second shooting module 302, and the second transmission module 301 is connected with the second shooting module 302; the second shooting module 302 is configured to obtain second video data through shooting, and the second transmission module 301 is configured to transmit the second video data to the master camera. And the second video data obtained by shooting by the auxiliary camera can be transmitted according to a mirror image code stream mode. The mirror image code stream adopts a third definition coding format. The third definition may be less than or equal to the second definition. Compared with the main camera, the auxiliary camera does not need to perform data processing, configuration and other work, and the auxiliary camera does not perform any processing after shooting the video data and directly uploads the video data to the main camera. By using a low-cost auxiliary camera, the deployment cost of the monitoring system can be reduced.
In an exemplary embodiment, one or more secondary cameras may be deployed around the primary camera to cover the blind spot of the primary camera in order to support the primary camera for dead-corner-free monitoring. Wherein, a certain distance can be kept between the main camera and the auxiliary camera, so that all information of a specific object can be monitored through the auxiliary camera. For example, in a straight lane scene, a main camera may be deployed at an entrance of the straight lane, one or more auxiliary cameras may be deployed at an exit of the straight lane, and front and rear images of a person passing through the straight lane can be seen through videos shot by the main camera and the auxiliary cameras. For another example, in a crossroad scene, a main camera can be deployed at the center of the crossroad, and an auxiliary camera is deployed at each of four directions of the main camera; as shown in fig. 4, the auxiliary cameras A, B, C, D are disposed at four positions of the main camera, so that the front, rear, left, and right images of the person passing through the intersection can be seen by the videos taken by the main camera and the auxiliary cameras.
In an exemplary embodiment, the monitoring server may store attribute information of the master camera and the first video data and the second video data associated with the master camera. Wherein the attribute information of the master camera may include at least one of: the name and the number of the main camera, the longitude and latitude information of the position of the main camera and the address information of the main camera. However, this is not limited in this application. In one example, as shown in fig. 1, the monitoring server 101 may store and maintain user information, user permissions, camera profiles, configuration management information (e.g., upgrade information of the main camera, etc.). The camera profile may record attribute information of the main camera (for example, name, number, address information, and the like of the main camera), user information associated with the main camera, user rights required for viewing a video captured by the main camera, real-time video data associated with the main camera, historical video data, and the like. In this example, the monitoring server only needs to maintain the information of the main camera, does not need to maintain the information of the auxiliary camera, and can obtain the monitoring video without dead angles by searching the main camera when obtaining the monitoring video, so that the maintenance and management cost is greatly reduced.
In an exemplary embodiment, after receiving an inquiry request from a terminal device, a monitoring server searches for first video data and second video data associated with a main camera according to attribute information of the main camera carried in the inquiry request, and provides the searched first video data and second video data to the terminal device.
In an exemplary embodiment, the naming rule of the second video data may include: carrying attribute information of the auxiliary camera. Wherein the attribute information of the secondary camera may include at least one of: the name and the number of the auxiliary camera, the longitude and latitude information of the position of the auxiliary camera and the address information of the auxiliary camera. However, this is not limited in this application. In this example, since the monitoring service end does not maintain the attribute information of the auxiliary camera, the monitoring service end can know which auxiliary camera the video data comes from according to the stored second video data by carrying the attribute information of the auxiliary camera in the name of the second video data, and since the second video data is stored in association with the main camera, the monitoring service end can also know which auxiliary cameras the main camera is associated with.
Fig. 5 is a flowchart of a monitoring method according to an embodiment of the present application. The monitoring method provided by the embodiment of the application is applied to a monitoring system, wherein the monitoring system comprises: the system comprises a main camera, one or more auxiliary cameras only having video shooting and data transmission functions and a monitoring server, wherein the auxiliary cameras are associated with the main camera. As shown in fig. 5, the monitoring method includes:
s501, the main camera receives second video data shot by the auxiliary camera;
s502, the main camera transmits the shot first video data and the second video data uploaded by the auxiliary camera to the monitoring server.
The monitoring method provided by the present embodiment is exemplified by an example based on the monitoring system shown in fig. 1. Fig. 6 is a diagram illustrating an example of a monitoring process of the monitoring system according to the embodiment of the present application. In this example, a user registered at the monitoring service may find a designated master camera at the monitoring service and query the monitoring video or image through the first video data and the second video data associated with the master camera.
In this example, during the deployment of the monitoring system, a field installer may deploy one or more auxiliary cameras around the main camera according to the actual situation, wherein the auxiliary cameras are used to cover the blind area of the main camera, and a certain distance may be kept between the main camera and the auxiliary cameras. The association between the primary and secondary cameras is determined during deployment. For example, the installer may specify on site which secondary camera or cameras the primary camera is to communicate with. The communication scheme between the auxiliary camera and the main camera can be various, such as wired, WIFI, bluetooth, and the like.
In this example, after the main camera and the auxiliary camera are deployed, the auxiliary camera uploads the shot second video data to the monitoring server through the main camera without any processing, and stores the second video data in the monitoring server in a mirror code stream manner; the first video data shot by the main camera is uploaded to the monitoring server and stored in the monitoring server in a main code stream or auxiliary code stream mode. Although the definition of the mirror image code stream and the secondary code stream is lower than that of the main code stream, higher image fluency can be obtained in remote transmission.
For example, the auxiliary camera may be connected to the main camera through a network cable, and then the captured video is transferred to the main camera without any processing, and the main camera is responsible for uploading the video to the monitoring server and storing the video in a mirror code stream manner.
For example, a WIFI hotspot is set in the main camera, a field installer ensures that the auxiliary camera is connected to the WIFI hotspot corresponding to the designated main camera, then the auxiliary camera can transmit a captured video to the main camera through the WIFI hotspot, and the main camera is responsible for uploading the video to the monitoring server and storing the video in a mirror code stream mode.
As shown in fig. 6, the monitoring process of the monitoring system provided in this embodiment includes:
s601, the main camera receives real-time second video data shot by the auxiliary camera.
S602, the main camera transmits the real-time first video data and the real-time second video data to the monitoring server.
It should be noted that the master camera may upload the first video data and the second video data separately, for example, after receiving the second video data. Or, the master camera may transmit the real-time first video data and the second video data to the monitoring server together after receiving the second video data. However, this is not limited in this application.
S603, the monitoring server receives the inquiry request from the terminal equipment.
The user can access the webpage through the terminal device, and perform corresponding operation on the webpage to generate a query request, for example, click a corresponding control for viewing the real-time monitoring video on the webpage.
The query request may carry attribute information (e.g., a number, address information, etc.) of the main camera to be searched, and may also carry data requirement information (e.g., real-time data or historical data is required).
The query request can also carry user information, and the monitoring server can check whether the user has the right to search the data associated with the corresponding main camera according to the user information. However, the present application is not limited to this comparison.
S604, the monitoring server searches first video data and second video data related to the main camera from the camera file according to the attribute information of the main camera. The monitoring server can find the real-time record and the historical record of the first video data and the second video data associated with the main camera according to the attribute information of the main camera.
And S605, the monitoring server provides the searched data to the terminal equipment.
For example, if the user wants to view a real-time image, the monitoring server may return the real-time first video data and the real-time second video data associated with the main camera to the terminal device, and the terminal device may display the real-time capturing record of the main camera and the real-time capturing record of the auxiliary camera on the display screen in a split-screen manner, for example, may view a 360 ° image of a person.
For example, if the user only wants to query video data shot by a certain auxiliary camera, the monitoring server can return the found second video data associated with the main camera to the terminal device, and the user selects the video data of the auxiliary camera to be viewed on the display screen of the terminal device according to the name of the second video data; or after the monitoring server finds the main camera, the monitoring server searches the video data of the auxiliary camera to be searched by the user according to the name of the second video data associated with the main camera, returns the searched video data to the terminal equipment, and displays the monitoring video or image through the display screen by the terminal equipment.
For example, if the user needs to view the non-real-time image, the monitoring server can find the designated main camera according to the query request of the user, and returns the historical video data associated with the main camera to the terminal device; the terminal equipment can display the history snapshot record of the main camera and the history snapshot record of the auxiliary camera in a split screen mode in the display screen, so that a user can find the snapshot record of a person corresponding to a certain time period conveniently. For example, when a police needs to search for an image of a suspect, the method of the embodiment can ensure that a 360-degree image corresponding to a person is seen at a certain time point, thereby improving the police handling efficiency.
In summary, the monitoring system and the monitoring method provided by the embodiment of the application can support monitoring without dead angles, and can greatly reduce deployment cost and management and maintenance cost.
In addition, an embodiment of the present application further provides a computer-readable storage medium, which stores a computer program, and when the computer program is executed, the computer program implements the steps of the monitoring method described above.
