Description

Technical Field

[0001] The utility model relates to the field of video analysis, and particularly relates to a device for assisting in marking trajectories in a video. Background Art

[0002] Trajectories in a video generally refer to the results of identifying and tracking the movement paths of vehicles, pedestrians, animals, or other moving objects between consecutive frames in video analysis. This tracking process creates a record of positions over time for each object, thus forming a coherent "trajectory line". Such trajectories can be two-dimensional, depicting the horizontal and vertical movements of objects within the video plane. In fields such as traffic monitoring, sports analysis, and security monitoring, this trajectory information is very valuable. In the event of a traffic accident or illegal act, the drawn path can help reconstruct the course of the event and provide important clues for accident liability determination and legal evidence collection. Trajectories in a video are usually directly viewed by investigators with the naked eye. When dealing with videos with complex scenes, it requires repeated viewing by personnel, and the operation is rather cumbersome and inconvenient.

[0003] Therefore, it is necessary to design a device for assisting in marking trajectories in a video that can draw and mark the trajectories of vehicles or pedestrians in traffic videos, making it easier to visually view the route trajectories of vehicles or pedestrians, and can be conveniently viewed by others to help reconstruct the course of traffic accidents.
