METHOD FOR IDENTIFYING VIDEO INVOLVING VIOLATION AT INTERSECTION BASED ON COORDINATED RELAY OF VIDEO CAMERAS

WIPO Patent Application WO/2020/000251

A1

The present invention relates to a method for identifying a video involving a violation at an intersection based on a coordinated relay of video cameras. The method comprises: step S1: calibrating a lane line, and identifying a lane indication sign; step S2: detecting a target vehicle according to an image collected by a first video camera to determine a lane where the target vehicle is located; and tracking the target vehicle according to the image collected by the first video camera to obtain a vehicle moving trajectory; and step S3: identifying, according to the lane where the target vehicle is located and the vehicle moving trajectory, whether the target vehicle changes lanes illegally. According to the present invention, analyzing and identifying the video collected by a video camera can simultaneously detect behaviors such as illegal driving on a solid line, illegal lane change, converse running, speeding, and running a red light, of multiple motor vehicles, occurring at an intersection, and the method is applicable to the situations having roads with long and solid lines at crossroads. The method is simple and practical, and facilitates construction, and may be transformed directly based on the original system and has good expansibility.
