Fig. 2 is a schematic flow chart of a regional security monitoring method according to an embodiment of the present disclosure. The zone safety monitoring method of fig. 2 may be performed by the control center 101 of fig. 1. As shown in fig. 2, the regional security monitoring method includes:
step S201, performing area division on an area to be monitored to obtain a first monitoring area and a second monitoring area, wherein the first monitoring area is a shooting view coverage area of the high-altitude monitoring device in an association relationship with the first monitoring area, and the second monitoring area is a shooting view blind area of the high-altitude monitoring device.
The area to be monitored may be some public areas (e.g., public places in enclosed areas such as shopping malls and hotels), or some private areas (e.g., indoor areas of private residences).
The following describes the technical solution of the present disclosure in detail by taking the area to be monitored as a public place of a certain mall as an example.
Referring to FIG. 3, it is assumed that four corners of the area to be monitored are respectively provided with a high altitude monitoring device (numbered as high altitude monitoring devices 01, 02, 03 and 04) and high altitude monitoring devices 01, 02, 03 and 04
The coverage areas of the shooting visual field (i.e. the space range that can be shot by the high-altitude monitoring device) are respectively the areas marked with the numbers of (i), (ii), (iii) and (iv) in fig. 3, the areas marked with the numbers of (i), (ii), (iii) and (iv) are the first monitoring area of the area to be monitored, and the remaining cross-shaped area (i.e. the area marked with the number of (v)) in the middle part is the second monitoring area of the area to be monitored (the area is the shooting visual field blind area of the high-altitude monitoring device, i.e. the space range that cannot be shot by the high-altitude monitoring device).
Further, the association (e.g., mapping) between the above-mentioned area to be monitored (which is assumed to be marked as a) and the four high altitude monitoring apparatuses 01, 02, 03 and 04, and the first monitoring area a1 and the second monitoring area a2 may be established as follows: the correlation among the area to be monitored, the first monitoring area and the high-altitude monitoring device 01 is [ A, A1,01 ]; the correlation among the area to be monitored, the first monitoring area and the high-altitude monitoring device 02 is [ A, A1,02 ]; the correlation among the area to be monitored, the first monitoring area and the high-altitude monitoring device 03 is [ A, A1,03 ]; the relationship among the area to be monitored, the first monitoring area, and the high altitude monitoring apparatus 04 is [ a, a1,04 ].
Step S202, calling a high-altitude monitoring device to acquire a first monitoring image of a first monitoring area so as to realize monitoring of the first monitoring area, wherein the first monitoring image carries first position information.
In an embodiment, the control center 101 may obtain the area to be monitored first, and then call the high-altitude monitoring device corresponding to the area to be monitored to acquire the first monitoring image of the first monitoring area in real time according to the association relationship between the area to be monitored and the high-altitude monitoring device.
For example, referring to fig. 3, if the control center 101 acquires that the area to be monitored is a, the control center may further acquire four high- altitude monitoring devices 01, 02, 03, and 04 associated with the area to be monitored a, and then invoke the high- altitude monitoring devices 01, 02, 03, and 04 to monitor the first monitoring area of the area to be monitored a. Specifically, the high-altitude monitoring device 01 can be called to monitor the area I, the high-altitude monitoring device 02 can monitor the area II, the high-altitude monitoring device 03 can monitor the area III, and the high-altitude monitoring device 04 can monitor the area IV. The monitoring image acquired by the high-altitude monitoring device 01 carries the position information of the area I, the monitoring image acquired by the high-altitude monitoring device 02 carries the position information of the area II, the monitoring image acquired by the high-altitude monitoring device 03 carries the position information of the area III, and the monitoring image acquired by the high-altitude monitoring device 04 carries the position information of the area IV. In this example, the first monitoring image includes monitoring images acquired by the high altitude monitoring apparatuses 01, 02, 03, and 04.
Step S203, the low-altitude movement monitoring device is called to move and acquire a second monitoring image of a second monitoring area according to a preset movement route so as to monitor the second monitoring area, where the second monitoring image carries second position information.
In one embodiment, at least one low-altitude mobile monitoring apparatus (e.g., a mobile robot with a camera mounted thereon) may be invoked to acquire a second monitoring image of the region (i.e., the second monitoring region) in real time while moving according to a preset moving route (e.g., the moving route a → b → c → d as shown in fig. 3). The second monitoring image carries real-time position information (i.e., second position information) of the second monitoring image acquired in real time.
It should be noted that the preset moving route may be flexibly set according to the actual situation, for example, it may be b → a → c → d, or c → a → b → d, etc., and is not limited in this disclosure.
According to the technical scheme provided by the embodiment of the disclosure, a first monitoring area and a second monitoring area are obtained by dividing the area to be monitored, wherein the first monitoring area is a shooting view coverage area of a high-altitude monitoring device which is in an association relation with the first monitoring area, and the second monitoring area is a shooting view blind area of the high-altitude monitoring device; calling a high-altitude monitoring device to acquire a first monitoring image of a first monitoring area so as to realize monitoring of the first monitoring area, wherein the first monitoring image carries first position information; and calling the low-altitude moving monitoring device to move and acquire a second monitoring image of a second monitoring area according to a preset moving route so as to realize monitoring of the second monitoring area, wherein the second monitoring image carries second position information, so that all-around and dead-angle-free safety monitoring of the area to be monitored can be well realized, and the potential safety hazard of the area to be monitored (such as a public area) is greatly reduced.
In some embodiments, the step S201 includes:
acquiring an electronic map of an area to be monitored and equipment information of a high-altitude monitoring device related to the area to be monitored, wherein the equipment information at least comprises installation position information and shooting visual field information of the high-altitude monitoring device;
and determining a first monitoring area and a second monitoring area according to the electronic map and the equipment information.
As an example, assuming that comprehensive security monitoring is performed on the area a to be monitored, the control center 101 may first obtain an electronic map of the area a to be monitored, where the electronic map includes buildings in the area a to be monitored and specific conditions of each part of the area (for example, specific information including area size, road direction, length, width, and the like of each part of the area). Meanwhile, the equipment information of the high-altitude monitoring device associated with the area A to be monitored can be acquired. In connection with the above example, the high altitude monitoring apparatus associated with the area a to be monitored includes the high altitude monitoring apparatuses 01, 02, 03, 04, that is, the device information of the high altitude monitoring apparatuses 01, 02, 03, 04 is further acquired. Specifically, the installation position information and the shooting view information of the high- altitude monitoring devices 01, 02, 03 and 04 are acquired.
According to the installation position information and the shooting visual field information of the high- altitude monitoring devices 01, 02, 03 and 04, the visual field space range which can be shot by the high-altitude monitoring devices can be determined, and therefore the monitoring area corresponding to each high-altitude monitoring device can be further determined, namely the monitoring area corresponding to the high-altitude monitoring device 01 is the area I, the monitoring area corresponding to the high-altitude monitoring device 02 is the area II, the monitoring area corresponding to the high-altitude monitoring device 03 is the area III, and the monitoring area corresponding to the high-altitude monitoring device 04 is the area IV. Therefore, the first monitoring area (including the areas I, II, III and IV) can be further determined, the first monitoring area is planed from the area A to be monitored, and the rest area is the second monitoring area.
According to the technical scheme provided by the embodiment of the disclosure, the electronic map of the area to be monitored and the equipment information of the high-altitude monitoring device associated with the electronic map are acquired, the accessible space range of the shooting field of the high-altitude monitoring device is further determined according to the information, namely, the first monitoring area is determined, and the shooting field blind area of the high-altitude monitoring device of the area to be monitored, namely, the area easy to miss monitoring is further found, so that the low-altitude movable monitoring device is adopted to monitor the areas easy to miss monitoring in the follow-up process, the shooting blind area of the high-altitude monitoring device is made up, the monitoring dead angle is reduced, and the omnibearing and dead-angle-free safety monitoring of the area to be monitored is realized.
In some embodiments, the step S202 includes:
sending a first shooting instruction to a high-altitude monitoring device to start the high-altitude monitoring device to snapshot a first monitoring area to obtain a snapshot image;
judging whether a target object and/or a target behavior action exist in the snapshot image;
if the target object and/or the target behavior action exist in the snapshot image, judging whether the image definition of the snapshot image is within a preset definition range;
and if the image definition of the snapshot image is within a preset definition range, determining the snapshot image as a first monitoring image.
In an embodiment, assuming that the area to be monitored is the area a to be monitored, the first shooting instruction may be sent to the associated high- altitude monitoring apparatuses 01, 02, 03, and 04 at the same time, and after receiving the first shooting instruction, the high- altitude monitoring apparatuses 01, 02, 03, and 04 start the shooting function to capture their respective areas. For example, the high altitude monitoring apparatus 01 takes a snapshot of the first region to obtain a snapshot image.
The following flow will be described in detail with reference to a snapshot image obtained by the high altitude monitoring apparatus 01 by capturing the first region as an example.
In an embodiment, after acquiring the captured image acquired by the high-altitude monitoring device 01, the control center 101 may perform image recognition and analysis processing on the captured image, specifically, may recognize and analyze whether the captured image includes a target object (for example, a face of a criminal suspect) by using a face recognition technology, and recognize and analyze whether the captured image includes a target behavior (for example, a preset body motion of a theft behavior, etc.) by using a motion recognition technology. For example, if it is determined that the captured image includes a predetermined theft limb movement (e.g., a limb movement of a person putting his hand into a handbag of another person), it may be further determined whether the image clarity (i.e., image resolution) of the captured image is within a predetermined clarity range. The preset definition range may be flexibly set according to an actual situation, for example, may be set to be greater than 100dpi, and the like, which is not limited herein.
For example, if the preset definition range is greater than 100dpi and the definition (image resolution) of the captured image is 200dpi (greater than 100 dpi), it may be determined that the definition of the captured image is within the preset definition range, and at this time, the captured image may be determined as the first monitored image.
In some embodiments, if the image definition of the snapshot image is not within the preset definition range, separating a target image area containing the target object and/or the target behavior action and a background image area containing no target object and/or target behavior action from the snapshot image;
determining a first pixel number of the target image area and a second pixel number of the background image area;
when the current focal length of the high-altitude monitoring device is determined to be adjusted according to the first pixel number and the second pixel number, the current focal length of the high-altitude monitoring device is automatically adjusted to a target focal length;
and sending a second shooting instruction to the high-altitude monitoring device so that the high-altitude monitoring device can shoot the first monitoring area in a snap mode according to the target focal length to obtain a first monitoring image.
In an exemplary embodiment, if the preset definition range is greater than 100dpi, and the definition (image resolution) of the captured image is 72dpi (less than 100 dpi), that is, the definition of the captured image is not within the preset definition range, a target image region in which a target object and/or a target behavior act can be extracted from the captured image by using a matting technique, and the remaining partial region is a background image region which does not contain the target object and/or the target behavior act.
For example, if the snapshot image includes a target object (e.g., a face of a criminal suspect), the face and body of the criminal suspect may be extracted by a matting technique, the extracted part is a target image region, and the remaining part is a background image region.
After separating the target image area and the background image area from the snap-shot image, a first pixel count of the target image area and a second pixel count of the background image area are calculated, respectively. The first number of pixels can be calculated by multiplying the height and width of the target image area, and the second number of pixels can be calculated by multiplying the height and width of the background image area.
Then, the ratio of the first pixel number to the second pixel number can be further calculated to judge whether the imaging area of the target object in the shooting field of view is changed, and if the imaging area of the target object in the shooting field of view is changed, the current focal length of the high-altitude monitoring device needs to be adjusted. At this time, the target focal length required to be adjusted may be further determined according to the ratio of the first pixel number to the second pixel number. For example, if the first pixel count/the second pixel count = x and the target focal length corresponding to x is y1 and the current focal length of the high altitude monitoring apparatus is y0, as determined from the preset correspondence table between the pixel ratio and the shooting focal length, the current focal lengths y0 to y1 of the high altitude monitoring apparatus may be automatically adjusted.
After receiving the second shooting instruction sent by the control center, the high-altitude monitoring device may capture the first monitored area by using the target focal length y1, obtain a first monitored image, and upload the first monitored image to the control center 101.
In some embodiments, automatically adjusting the current focal length of the high altitude monitoring apparatus to the target focal length includes:
acquiring a zooming step length and a current focal length of the high-altitude monitoring device;
and adjusting the current focal length of the high-altitude monitoring device to the target focal length according to the zooming step length.
The zoom step refers to the amplitude of the focal length and the frequency of the high-altitude monitoring device. For example, the focal length xx mm is increased/decreased within 1 second.
As an example, assuming that the zoom step size of the high altitude monitoring apparatus 01 is increased by 5mm within 1 second, and the current focal length thereof is 75mm, a preset zoom program (programmed in advance) may be triggered to be started to adjust the focal length of the high altitude monitoring apparatus 01 from the current focal length of 75mm to the target focal length of 80mm within 1 second.
The embodiment of the disclosure sends a first shooting instruction to a high-altitude monitoring device to obtain a snapshot image, and when a target object and/or a target behavior action may exist in the snapshot image is identified, further determines whether the definition of the snapshot image meets a preset definition range, and if the definition of the snapshot image does not meet the preset definition range, further determines whether the focal length of the high-altitude monitoring device needs to be adjusted, and if the focal length needs to be adjusted, automatically adjusts the current focal length of the high-altitude monitoring device to a target focal length, and enables the high-altitude monitoring device to snapshot a clearer first monitoring image by using the target focal length, so that a subsequent control center can further accurately determine whether an event alarm (such as occurrence of a suspect, occurrence of a theft event, and the like) occurs in the area according to the clearer first monitoring image, thereby effectively ensuring the safety in the area to be monitored.
In some embodiments, the step S203 includes:
calculating the area of the second monitoring area, and dividing the second monitoring area into a plurality of patrol areas according to the area;
distributing a target low-altitude mobile monitoring device for each patrol area;
and issuing a patrol monitoring task to each target low-altitude mobile monitoring device so that each target low-altitude mobile monitoring device executes the corresponding patrol monitoring task to realize monitoring of the second monitoring area, wherein the patrol monitoring task at least comprises basic information of the patrol area corresponding to the target low-altitude mobile monitoring device and a mobile route map.
In the process of moving patrol monitoring of the low-altitude mobile monitoring devices in the second monitoring area, the number of the low-altitude mobile monitoring devices is too small due to the fact that the area of the second monitoring area is too large; or the moving speed, the moving route, and the moving route of the low-altitude moving monitoring device may be affected by some obstacles (such as pedestrians, goods, etc.), so that the low-altitude moving monitoring device cannot timely and comprehensively monitor various positions of the second monitoring area. This makes it easy to provide a potential safety hazard to a lawbreaker (such as a thief) who may learn information about a dead zone in the first monitoring area and a moving route of the low-altitude mobile monitoring apparatus in the second monitoring area in some way to implement a lawbreak (such as stealing property of another person).
As an example, in order to solve the above problem, in the embodiment of the present disclosure, a region area of the second monitoring region is calculated first, and then it is determined how many low-altitude mobile monitoring devices need to be allocated according to the region area to perform comprehensive and timely effective safety monitoring on the second monitoring region.
With reference to the above example, the second monitored area is the region of the region to be monitored a. The control center can calculate the area of the second monitoring area (namely, the fifth area) according to the electronic map of the area A to be monitored and the dividing boundary of the first monitoring area and the second monitoring area. And then determining how many low-altitude mobile monitoring devices need to be distributed according to the area of the area to realize the omnibearing real-time patrol monitoring on the second monitoring area.
For example, when it is determined that four low-altitude mobile monitoring devices need to be allocated according to the area of the region to realize the comprehensive real-time monitoring of the region, the second monitoring region may be divided into four patrol regions a, b, c and d. And then, distributing a target low-altitude mobile monitoring device for the patrol areas a, b, c and d, and issuing patrol monitoring tasks to each target low-altitude mobile monitoring device so that each target low-altitude mobile monitoring device executes the corresponding patrol monitoring task. For example, the target low altitude movement monitoring device 01 is allocated to the patrol area a, and the target low altitude movement monitoring device 01 may move to the patrol area a according to basic information of the patrol area a (e.g., position information of the patrol area a) and move in the patrol area a according to a preset movement route map (movement route map in the patrol area a) to perform patrol monitoring.
In some embodiments, issuing a patrol monitoring task to each target low-altitude mobile monitoring apparatus to enable the target low-altitude mobile monitoring apparatus to execute the corresponding patrol monitoring task, and after monitoring of the second monitoring area is implemented, the method further includes:
responding to fault information reported by fault reporting equipment, wherein the fault information comprises current position information of the fault reporting equipment and a first patrol monitoring task corresponding to the current position information;
determining a target low-altitude mobile monitoring device closest to the fault reporting equipment as cross-region patrol equipment according to the current position information of the fault reporting equipment;
acquiring a second patrol monitoring task corresponding to the trans-regional patrol equipment;
replanning according to the first patrol monitoring task and the second patrol monitoring task to generate a cross-region patrol monitoring task;
and issuing a cross-region patrol monitoring task to cross-region patrol equipment so that the cross-region patrol equipment performs patrol monitoring on a patrol area which is responsible for the fault reporting equipment and a patrol area which is originally responsible for the fault reporting equipment.
In an embodiment, in combination with the above example, it is assumed that the target low-altitude mobile monitoring apparatus 01 (i.e., the fault reporting device) in the patrol area a reports fault information to the control center due to a fault (e.g., a battery is out of power, a camera cannot work normally, etc.), where the fault information includes current location information and a corresponding first patrol monitoring task (i.e., the patrol monitoring task for the patrol area a, which includes location information of the patrol area a and a movement route map in the patrol area a). The control center responds to fault information reported by the fault reporting equipment, obtains current position information of the fault reporting equipment and position information of target low-altitude mobile monitoring devices 02, 03 and 04 normally used in other patrol areas b, c and d, respectively calculates distance values between the fault reporting equipment and the target low-altitude mobile monitoring devices 02, 03 and 04, compares the three groups of distance values, and determines the group of target low-altitude mobile monitoring devices with the minimum distance value as cross-region patrol equipment. For example, assuming that the distance value between the fault reporting device and the target low-altitude mobile monitoring apparatus 02 is the smallest, the target low-altitude mobile monitoring apparatus 02 may be determined as a cross-region patrol device.
Then, the control center may further obtain a second patrol monitoring task (i.e., a patrol monitoring task for the patrol area b, including the location information of the patrol area b and the movement route map in the patrol area b) of the target low-altitude mobile monitoring apparatus 02.
