Vehicle illegal turning behavior detection method based on tracking

The invention relates to a vehicle illegal turning behavior detection method based on tracking. The method comprises the following steps of: firstly selecting an interest area from the right of a road, and extracting the position of the vehicle entering the interest area as a start position area of the candidate illegal turning vehicle, wherein the interest area includes all right lanes in the road; performing Meanshift tracking on the vehicle detected in the interest area of the road, and recording the coordinate position of the vehicle in each frame of the video; and analyzing the historical coordinates of the vehicle in the traffic scene, and judging whether the vehicle conducts illegal turning behavior according to the historical coordinate value in the vehicle area and the characteristics of the driving direction of the tracked vehicle in the driving process. Through the invention, analysis on multiple lanes going through during illegal turning as well as the complicated motion of the vehicle is not required, thus the detection method is simplified.
