Second embodiment
Referring to fig. 2, fig. 2 shows a method flow of a civil air defense visualization method according to a second embodiment of the present invention, where the method is applied to a server. The method flow of the civil air defense visualization method comprises the following steps: step S100, step S200, step S300, and step S400.
Step S100: and acquiring the position information of each mobile terminal, and acquiring the quantity information of the mobile terminals at the entrance of each civil air defense project according to the position information of each mobile terminal.
The server acquires the position information of each mobile terminal through the wireless mobile data network. It is to be understood that the location information of each mobile terminal is a coordinate location of the mobile terminal. The server is preset with a coordinate position at each civil air defense project entrance and a preset distance at each civil air defense project entrance, wherein the preset distance is the maximum distance from the coordinate position at each civil air defense project entrance to the coordinate position at the civil air defense project entrance by taking the coordinate position at each civil air defense project entrance as a circle center. And after the server acquires the coordinate position of each mobile terminal, calculating a distance difference value between the coordinate position of each mobile terminal and the coordinate position of each civil defense project entrance. And when the distance difference is within the preset distance, the server considers that the mobile terminal is positioned at the entrance of the civil air defense project. And then the server acquires the number information of the pre-mobile terminals at each civil air defense project entrance, namely the number of the workers at each civil air defense project entrance.
Step S200: and acquiring the shot video at the entrance of the civil air defense project sent by each camera within the preset time.
The server is provided with preset time and is coupled with each camera through a data line. Therefore, the server can obtain the video sent by each camera within the preset time, wherein each video is the video at the entrance of the civil air defense project shot by the camera. In this embodiment, if the preset time is, for example, 1 minute, the server can obtain the video with the duration of 1 minute according to the preset time, that is, after the server obtains the video with the duration of 1 minute, the mobile terminal starts to obtain the next video with the duration of 1 minute while processing the video, so as to form a cycle.
Step S300: according to the change of the coordinates of each person in the video, the crowd flow passing through the entrance of each civil air defense project in the preset time is obtained.
When the server processes each acquired video, the server identifies and marks each person entering from the entrance of the civil air defense project in each video, and acquires the coordinates of each person at the entrance of the civil air defense project in the video.
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 defense project in the video also change. When a person moves to an edge at the civil air defense entrance, the coordinates of the person are also the edge at the civil air defense entrance. The server determines that the person is at the entrance of the video through 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 server acquires in the preset time through the mode of accumulation, and in the video, the total number of people at the entrance of the civil air defense project is the crowd flow at the entrance of the civil air defense project.
It can be understood that the server processes each video in the same manner, and the server 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.
Step S400: and judging whether each crowd flow is matched with the quantity information of the mobile terminal at the entrance of the civil air defense project, and if not, sending the video corresponding to each unmatched crowd flow to the display terminal.
After the server acquires the quantity information of the mobile terminals at the inlet of each civil air defense project, the server acquires preset crowd flow corresponding to the quantity information of the mobile terminals at the inlet of each civil air defense project according to different preset crowd flow. For example, the larger the numerical value of the quantity information is, the larger the value of the preset crowd flow rate corresponding to the quantity information is, and conversely, the smaller the numerical value of the quantity information is, the smaller the value of the preset crowd flow rate corresponding to the quantity information is. The server judges whether each crowd flow is matched with the quantity information of the mobile terminals at the entrance of the civil air defense project, namely, the server judges whether the crowd flow at the entrance of the civil air defense project is matched with the preset crowd flow at the entrance of the civil air defense project, and obtains a judgment result obtained based on the judgment of each crowd flow. When the server learns that the judgment is not matched according to the judgment result, the server sends the video corresponding to each unmatched crowd flow to the display terminal, so that the display terminal displays the video corresponding to each unmatched crowd flow, and then the staff in the central control room preferentially and intensively pay attention to the civil air defense project with a large number of people to be evacuated through the display terminal.
Referring to fig. 3, fig. 3 shows a method sub-flow of step S300 in a civil air defense visualization method according to a second embodiment of the present invention. Specifically, the method sub-process of step S300 includes: step S310, step S320, and step S330.
Step S310: marking each person entering the civil air defense project entrance from a first preset boundary in each video, and acquiring the coordinates of each marked person in the video.
After the server acquires each video, the server 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 a first preset boundary for each video, the movement of the target object can be identified by the server 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 server as an example. After each target object enters the image through the first preset boundary, the server extracts the image through the edge image. And acquiring the trunk characteristic information of each target object. In this embodiment, the server can carry out the degree of depth study to human appearance characteristic to the storage is predetermined trunk characteristic information. Wherein, predetermine the trunk characteristic information and can be: the connecting features of the head, torso and arms. And the server compares each extracted trunk characteristic information with preset trunk characteristic information and obtains a comparison similarity value. It is understood that the server performs comparison according to the connection between the head and the trunk and the connection between the trunk and the arms when obtaining the similarity value. If the two connection characteristics are matched, the similarity value is 100 percent; 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 0%. In addition, the server also stores a comparison similarity threshold, which may be 49%. If the comparison similarity value of the target object is larger than or equal to the comparison similarity threshold value, the server 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 server can resolve the entrance of the civil air defense project into a two-dimensional coordinate system, so that the marked vehicle 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. The server can obtain the coordinates of the marked point of each marked person at the entrance of the video to the civil air defense project.
It will be appreciated that the server obtains the coordinates of each tagged person in each video by processing each video in the same manner as described above.
Step S320: and tracking the change of each coordinate in each video at the civil air defense project entrance, and accumulating the number of people passing through the civil air defense project entrance once when the coordinate in each video moves to a second preset boundary at the civil air defense project entrance.
After the server acquires the coordinates of the marking points of each marked person in each video, if the person moves at the entrance of the civil air defense project of the video, the coordinates of the person at the entrance of the civil air defense project correspondingly change, and the server can track the change of the coordinates of each portrait 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. The server determines that the tracked person in the video has moved to a second predetermined boundary. At this time, the server 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.
Step S330: and acquiring the crowd flow of the accumulated sum of the passing number of people at the entrance of each civil air defense project within the preset time.
The preset time set by the server may be 1 minute to match the variability of the actual situation. And the server counts the number of people of each video passing through the second preset boundary within a preset time. In each video, the server can accumulate the number of people passing through the entrance of the civil air defense project in the video once when the marked people move to the second preset boundary. By acquiring the accumulated sum of the number of passing people of each video accumulated for multiple times in the preset time, the server can acquire the number of passing people of each video in the preset time, and the number of passing people is the crowd flow at the entrance of the civil air defense project.
Referring to fig. 4, fig. 4 shows a method sub-flow of step S400 in a civil air defense visualization method according to a second embodiment of the present invention. Specifically, the method sub-process of step S400 includes: step S410 and step S420.
Step S410: and judging whether each crowd flow is matched with the quantity information of the mobile terminal at the entrance of the civil air defense project or not, and acquiring a judgment result.
The server is preset with different preset crowd flow. After the server acquires the quantity information of the mobile terminals at the inlet of each civil air defense project, the server matches the preset crowd flow corresponding to the quantity information of the mobile terminals at the inlet of each civil air defense project according to the matching relation between the quantity information of the mobile terminals at the inlet of each civil air defense project and the preset crowd flow. For example, the different preset crowd flow preset by the server may include: a preset crowd flow of 0-50, a preset crowd flow of 51-100, a preset crowd flow of 101-150 and a preset crowd flow of 151-200. And the matching relationship between the quantity information of the mobile terminal at the entrance of the civil air defense project and the preset crowd flow is as follows: the number information of the mobile terminals is 1-5 matched with the preset crowd flow of 0-50, the number information of the mobile terminals is 6-10 matched with the preset crowd flow of 51-100, the number information of the mobile terminals is 11-15 matched with the preset crowd flow of 101-150, and the number information of the mobile terminals is 16-20 matched with the preset crowd flow of 151-200. And when the number information of the mobile terminals at the entrance of a certain civil air defense project is 10, according to the matching relation, the server acquires that the preset crowd flow at the entrance of the civil air defense project is 51-100.
After the server acquires the preset crowd flow corresponding to the entrance of each civil air defense project, the server matches the entrance crowd flow of each civil air defense project with the preset crowd flow of the entrance of the civil air defense project. And judging whether the crowd flow at the inlet of each civil air defense project is matched with the preset crowd flow at the inlet of the civil air defense project. The server obtains a total judgment result based on the judgment of the flow rate of each crowd through the judgment of the flow rate of each crowd. For example, the crowd flow at the entrance of the civil air defense project A is 78, the preset crowd flow at the entrance of the civil air defense project A is 50-100, the crowd flow at the entrance of the civil air defense project B is 132, the preset crowd flow at the entrance of the civil air defense project B is 50-100, the crowd flow at the entrance of the civil air defense project C is 182, the preset crowd flow at the entrance of the civil air defense project C is 50-100, the crowd flow at the entrance of the civil air defense project D is 46, and the preset crowd flow at the entrance of the civil air defense project C is 50-100. The server generates a judgment result based on all the judgments as follows: the crowd flow at the entrance of A people's air defense engineering matches with the crowd flow of presetting at the entrance of A people's air defense engineering, and the crowd flow at the entrance of B people's air defense engineering and the crowd flow of presetting at the entrance of B people's air defense engineering do not match, and the crowd flow at the entrance of C people's air defense engineering and the crowd flow of presetting at the entrance of C people's air defense engineering do not match, and the crowd flow at the entrance of D people's air defense engineering matches with the crowd flow of presetting at the entrance of D people's air defense engineering.
Step S420: and when the judgment result is that at least one crowd flow is not matched, sending the video corresponding to the unmatched crowd flow to the display terminal.
After the server obtains the judgment result, the server selects which video at the entrance of the civil air defense project is sent to the display terminal according to the preset control program of the server on the basis of the judgment result.
Specifically, when the judgment result obtained by the server is that each crowd flow is judged to be matched with the preset crowd flow corresponding to the crowd flow. The server acquires that the number of the people evacuated to each civil air defense project is matched with the number of the staff corresponding to the number information of the mobile terminals of the civil air defense project based on the judgment result, namely the number of the people of each civil air defense project is within the staff control range of the civil air defense project. The server sends the video corresponding to each crowd flow to the display terminal so that workers in the central control room can watch each video conveniently, and overall control is conducted on evacuation work of each civil defense project.
When the judgment result obtained by the server is that at least one crowd flow is not matched with the preset crowd flow corresponding to the crowd flow. The server learns that the number of the people evacuated to each unmatched civil air defense project is not matched with the number of the staff corresponding to the number information of the mobile terminals of the civil air defense project based on the judgment result, namely the number of the people evacuated to each unmatched civil air defense project exceeds the control range of the staff with a certain number of the civil air defense projects. The server sends the video corresponding to each unmatched crowd flow to the display terminal so that workers in the central control room can watch the video of each unmatched civil air defense project and focus on the evacuation condition of each unmatched civil air defense project.
As a mode, when the server sends the video corresponding to each unmatched crowd flow to the display terminal, the server firstly obtains the crowd flow with the largest flow value in the unmatched crowd flow, and then sends the video corresponding to the crowd flow with the largest flow value to the display terminal preferentially relative to the videos corresponding to other unmatched crowd flows, so that workers in the central control room can pay attention to the civil air defense project with the largest evacuation number in the videos of the unmatched civil air defense project preferentially.
Also for example, the crowd flow at the entrance of the B-civil air defense project is 132, and the crowd flow at the entrance of the B-civil air defense project does not match the preset crowd flow at the entrance of the B-civil air defense project. The crowd flow at the entrance of the civil air defense project C is 182, and the crowd flow at the entrance of the civil air defense project C is not matched with the preset crowd flow at the entrance of the civil air defense project C. The server determines that the crowd flow rate for acquiring the civil air defense project C is 182, which is the largest value in the flow rates of the unmatched civil air defense projects B and the unmatched civil air defense projects C based on the determination result. And then the server sends the screen at the entrance of the civil air defense project C relative to the civil air defense project B to the display terminal, so that the evacuation work of the civil air defense project C is focused more preferentially by the workers in the central control room compared with the civil air defense project B.
