s1.1, a user sends a command for controlling the focusing of a holder of the physical camera to the cloud platform module;
s1.2, the cloud platform module sends a control instruction to the video management platform module through the SDK;
s1.3, controlling a physical camera by the video management platform module through a private protocol, executing the control instruction by the physical camera, and controlling the rotation and the focusing of a holder;
s1.4, the cloud platform module penetrates through hardware by using a management intranet, and current PTZ parameters of the physical camera are obtained through peanut shell service;
s1.5, pulling a physical camera picture video stream by a video management platform module;
s1.6, the cloud platform module acquires a video picture through the SDK;
s1.7, the cloud platform module informs the BIM lightweight engine module of the obtained current PTZ parameter, and the BIM lightweight engine module adjusts the angle and the focal length of the BIM virtual camera according to the current PTZ parameter;
s1.8, the cloud platform module acquires a BIM picture;
s1.8, the cloud platform module obtains a video picture through the SDK and displays the BIM picture at the same time.
5. The management method according to claim 3, characterized in that: the image tracing steps are as follows:
s2.1, selecting the time for tracing the designated image by a user;
s2.2, the cloud platform module inquires the video at the appointed time through an API (application programming interface);
s2.3, the video management platform module calls an NVR video;
s2.4, the NVR returns the video clip to the video management platform module;
s2.5, the video management platform module returns the video clip to the cloud platform module;
s2.6, the cloud platform module sends user query time to the BIM lightweight engine module;
s2.7, returning the progress BIM of the time inquired by the user to the cloud platform module by the BIM lightweight engine module;
and S2.8, displaying the video record corresponding to the user query time and the BIM corresponding to the progress for the user by the cloud platform module.
