[0019] figure 1 A schematic flowchart of the method for monitoring a crowd of people gathered according to the first embodiment of the present application is shown. As shown in the figure, this embodiment mainly includes the following steps:

[0020] S102. According to the preset threshold of the number of people gathered, each target monitoring group meeting the preset threshold of the number of people gathered is acquired from each monitoring image.

[0021] Optionally, each monitoring image may be obtained by using each monitoring device (such as a monitoring camera) set in a public place.

[0022] Optionally, the acquired monitoring images may include panoramic images.

[0023] Optionally, it is possible to detect a crowd in the surveillance image and identify the number of people in the crowd, and when it is detected that the number of people in the crowd exceeds a preset threshold of the number of people in the crowd, the crowd is determined as the target surveillance ...

[0034] figure 2 It shows the crowd monitoring method of the second embodiment of the present application. This embodiment can be used as the pre-processing step of the above step S102. As shown in the figure, the method of this embodiment mainly includes the following steps:

[0035] Step S202, obtaining each monitoring image of each monitoring device and each monitoring area corresponding to each monitoring image.

[0036] Optionally, the monitoring device may include various types of cameras installed in designated areas of public places.

[0037] Step S204, according to the preset target area, each monitoring image whose monitoring area satisfies the preset target area is acquired.

[0038] Optionally, areas that need to be focused on in public places (such as patrol blind spots) can be set to generate preset target areas, so as to screen out each monitoring image that meets the preset target area from each monitoring image for subsequent execution. Analysis and processi...

[0042] image 3 A schematic flowchart of a method for monitoring a crowd of people gathered according to the third embodiment of the present application is shown. As shown in the figure, this embodiment mainly includes the following steps:

[0043] Continuing from the above step S102, continue to execute step S302, according to each target object identified from each target monitoring group, obtain the number of times that a target group consisting of at least two target objects is in each target monitoring group.

[0044] For example, according to each target object identified from each target monitoring group, the number of times of the same frame between each target object can be counted, for example, three target objects A, B, and C can be determined as a target group, And count the number of times the target group is in the same frame among the target monitoring groups.

[0045] Step S304, according to the preset same-frame threshold, obtain the target groups whose time...

Abstract

The invention provides a gathered crowd monitoring method and device and a computer storage medium, and the method mainly comprises the steps: obtaining each target monitoring crowd meeting a preset gathered crowd number threshold value from each monitoring image according to the preset gathered crowd number threshold value, carrying out the recognition of each target object from each target monitoring crowd according to each target object recognized from each target monitoring crowd, obtaining each target coincidence value corresponding to each target object, and determining each target object of which the target coincidence value exceeds a preset coincidence threshold value according to the preset coincidence threshold value. Therefore, clustering analysis can be carried out on the gathered crowd.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image recognition, and in particular to a method, device and computer storage medium for monitoring a crowd. Background technique [0002] The current crowd identification mainly relies on human judgment, which not only consumes a lot of manpower, but also is prone to misjudgment and missed judgment. [0003] In view of this, there is an urgent need for a technical solution that can automatically identify various groups of people gathered in public places. Contents of the invention [0004] In view of the above problems, the present application provides a crowd monitoring method, equipment and computer storage medium, which can perform cluster analysis on clustered crowds to identify clustered crowds. [0005] The first aspect of the present application provides a method for monitoring a crowd of people, which includes: according to the preset threshold of the number of peop...
