Video patrol method and device, electronic device, and readable medium

A video patrol device, comprising:

• an acquisition module configured to acquire video patrol information, wherein the video patrol information is video information acquired from a real scene in a patrolled area;
• a matching and combination module configured to match and combine the video patrol information with a 3D roaming scene to obtain a 3D patrol video, wherein the 3D roaming scene is a virtual scene obtained by simulating the real scene;
• and
• a display module configured to display the 3D patrol video,
• wherein the acquisition module comprises:
• a camera, a robot and an actual patrol rail,
• wherein the actual patrol rail is disposed in the real scene in the patrolled area, and is configured to provide a running track of the robot;
• the robot moves along the actual patrol rail;
• the camera is arranged on the robot which carries the camera to move in the real scene to acquire the video patrol information,
• before matching and combining the video patrol information with the 3D roaming scene to obtain the 3D patrol video, further comprising:
• obtaining the 3D roaming scene based on the real scene;
• simulating a 3D roaming patrol track in the 3D roaming scene according to an actual patrol rail;
• and
• calibrating a virtual position in the 3D roaming scene based on a current actual position of the robot and current patrol duration of the robot, wherein the current patrol duration is time consumed by the robot to reach the current actual position from an initial position of the actual patrol track,
• wherein calibrating a patrol position in the 3D roaming scene based on the current actual position of the robot and the current patrol duration of the robot in the real scene comprises:
• acquiring the current actual position of the robot on the actual patrol track and the corresponding current patrol duration of the robot;
• determining a current actual position scale parameter based on the current actual position and a total length of the actual patrol track;
• and
• calibrating the patrol position in the 3D roaming scene based on the current actual position scale parameter and the current patrol duration.
