Highway tunnel parking detection method based on video technology

The invention discloses a highway tunnel parking detection method based on a video technology. The method comprises the following steps: collecting video data in a highway tunnel; judging whether a vehicle exists in the video image or not and whether the vehicle moves; tracking the spatial position of the vehicle according to lanes to obtain track points of the vehicle running on the lanes, and connecting the positions of adjacent continuous frames of the vehicle in the image to form a track; judging whether a special trajectory exists in trajectory aggregation or not by adopting a k-mean aggregation algorithm, and if the special trajectory exists, generating lane change in the vehicle driving process; and when the number of vehicles changing lanes at the same position within a period of time is greater than or equal to a certain value, judging that a parking event occurs at the position. Collision accidents in the tunnel can be effectively avoided, the driving safety of the tunnel isensured, and the method h
