The display terminal 120 may be installed at an entrance of each civil air defense project for displaying evacuation conditions of each civil air defense project, or may be displayed on the display terminal 120 for reminding people of safety evacuation when a dangerous condition occurs.
Referring to fig. 2, fig. 2 is a flowchart of a crowd evacuation method according to an embodiment of the present invention, where the method is applied to a control terminal, and the method specifically includes the following steps:
step S110: and acquiring the flow of the crowd passing through the inlet of each civil air defense project through the Beidou satellite.
Still include a plurality of cameras among the crowd evacuation system, the entrance of civil air defense engineering is all installed to every camera, and every camera is in the during operation, and the video of the civil air defense engineering entrance of installing can be shot to the camera. Each camera is coupled with the control terminal through a data line, so that each camera can continuously send the shot video to the control terminal.
The control terminal is provided with the time of predetermineeing, control terminal can acquire in the time of predetermineeing every camera shooting the video of the entrance of civil air defense engineering, wherein, every video is the video of the entrance of the civil air defense that this camera was shot. In this embodiment, if the preset time is, for example, 1 minute, the control terminal can obtain the video with the duration of 1 minute according to the preset time, that is, after the control terminal obtains the video with the duration of 1 minute, the control terminal processes the video and starts to obtain the next video with the duration of 1 minute, so as to circulate.
When the control terminal processes each acquired video, each person entering from the entrance of the civil air defense project in each video is identified and marked, and the coordinates of each person at the entrance of the civil air defense project in the video are acquired.
Taking the processing of one of the videos as an example, as each person moves continuously, the coordinates of each person at the entrance of the civil air defense project in the video also change. When a person moves to the edge at the entrance to the civil air defense, the coordinates of the person are also located at the edge at the entrance to the civil air defense. And the control terminal judges that the person passes through the entrance of the civil air defense project according to the edge of the coordinate of the person at the entrance of the civil air defense project, and accumulates the number of the persons passing through the entrance of the civil air defense project once. The control terminal acquires the total number of people at the entrance of the civil air defense project in the video in the preset time in an accumulation mode, and the total number of people is the crowd flow at the entrance of the civil air defense project.
It can be understood that the control terminal processes each video in the same manner, and the control terminal obtains the crowd flow of the accumulated sum of the number of passing people at the entrance of each civil air defense project within the preset time according to each video.
Specifically, after each video is acquired, the control terminal sets an area at the entrance of the civil air defense project in each video as a first preset boundary according to a preset control program. Wherein the first preset boundary in each video may be at least one. By setting the first preset boundary for each video, the movement of the target object can be identified by the control terminal after entering the civil air defense project entrance of the video from the first preset boundary.
Take the processing of one of the videos by the control terminal as an example. After each target object enters the image through the first preset boundary, the control terminal obtains the trunk characteristic information of each target object through edge image extraction. In this embodiment, control terminal can carry out the degree of depth study to the appearance characteristic of human body to the storage is for predetermineeing trunk characteristic information, and wherein, predetermine trunk characteristic information and can be for: the connecting features of the head, torso and arms. And the control terminal compares each lifted trunk characteristic information with preset trunk characteristic information and obtains a comparison similarity value. It can be understood that when the control terminal obtains the similar value, the comparison is performed according to the connection between the head and the trunk and the connection between the trunk and the arms, and if the two connection features are compared and matched, the similar value is 100%; if only one of the characteristics is correctly compared, the similarity value is 50 percent; if both connection features do not match, the similarity value is 49%. If the comparison similarity value of the target object is larger than or equal to the comparison similarity threshold value, the control terminal can judge that the target object is a human body and mark each target object judged as the human body, wherein the mark point is the central point of the portrait. The hesitation control terminal can resolve the entrance of the civil air defense project into a two-dimensional coordinate system, so that the marked people can be located at a certain position of the entrance of the civil air defense project after entering the entrance of the civil air defense project from the first preset boundary, and the control terminal can acquire the coordinates of the marking point of each marked person at the entrance of the civil air defense project of the video.
Therefore, the control terminal can acquire the coordinates of the person marked in each video by processing each video in the same manner as described above.
After the control terminal acquires the coordinates of the marking points of each marked person in each video, if the person moves at the entrance of the video civil air defense project, the coordinates of the person at the entrance of the civil air defense project correspondingly change, and the control terminal can track the change of the coordinates of each person in each video.
As a way of example, another at least one area at the entrance of the civil air defense project of each video is set as a second preset boundary, and correspondingly, each second preset boundary also has coordinates at the entrance of the civil air defense project. In each video, when the coordinates of the tracked person are changed to be the same as the coordinates of at least one of the second preset boundaries, for example, the coordinates of the person are changed to: (12, 0) and the second predetermined boundary coordinate is (0-100, 0), then the person's y-bowl and the second predetermined boundary y-coordinate are the same. Therefore, the control terminal judges that the tracked person in the video correspondingly moves to the second preset boundary. At this time, the control terminal judges that the person passes through the entrance of the civil air defense project in the video, and accumulates the number of passing persons passing through the entrance of the civil air defense project once. The embodiment can set the people flow moving direction in each video by setting the first preset boundary and the second preset boundary for each video, and judge and count the passing number in the direction in each video.
The preset time set by the control terminal may be 1 minute to match variability of the actual situation. And the control terminal counts the number of people passing through the second preset boundary in the preset time of each video. In each video, when the marked people move to a second preset boundary, the control terminal can accumulate the number of people passing through the entrance of the civil air defense project in the video once. By acquiring the accumulated sum of the number of passing people of each video in the preset time, the number of passing people of each video in the preset time can be acquired, and the number of passing people of each video in the preset time is the crowd flow at the entrance of the civil air defense project.
Step S120: and judging whether the crowd flow passing through the entrance of each civil air defense project is in the corresponding preset crowd flow range.
For the purpose of crowd evacuation safety, the control terminal presets a safe evacuation crowd flow range of each civil air defense project, for example, if the preset crowd flow range of the safe evacuation crowd of a certain civil air defense project is 0-1000, if the obtained crowd flow at the entrance of the civil air defense project exceeds 1000 in the above step, step S130 is executed, and if the crowd flow at the entrance of the civil air defense project is within the above preset crowd flow range, step S140 is executed.
It should be noted that, according to the actual construction situation, the preset crowd flow range of each civil air defense project can be flexibly set according to the construction scale of each civil air defense project.
Step S130: and sending the position of the civil air defense project with the crowd flow at the entrance of the civil air defense project exceeding the preset crowd flow range of the civil air defense project to the display terminal.
If the control terminal judges that the crowd flow at the entrance of a certain civil air defense project exceeds the preset crowd flow range of the civil air defense project, the position of the civil air defense project is sent to the display terminal, so that workers at the entrance of the civil air defense project can timely understand which civil air defense project has larger evacuation pressure on the display terminal, flexible adjustment can be carried out, the crowd of the civil air defense project with large evacuation pressure is evacuated to the position of the civil air defense project with less crowd flow, of course, the control terminal can also send the positions of the civil air defense projects with the closest distance of the civil air defense project at the position with the largest crowd flow to the display terminal for display, and the workers can guide the crowd of the civil air defense project with the larger crowd flow to the civil air defense project with less crowd flow for evacuation, thereby effectively evacuating.
The control terminal can acquire the position information of each civil air defense project in advance through the Beidou satellite.
Step S140: and calculating the time required by people for evacuation in each civil air defense project according to the flow of the people passing through the entrance of each civil air defense project.
If the crowd flow that passes through at each civil air defense project's entrance is in the crowd flow scope of presetting that corresponds separately, then in order to further effectively carry out crowd evacuation, can calculate the crowd at the required time of each civil air defense project evacuation through the crowd flow.
