Abstract
The present invention relates to a technical field of traffic monitoring, and more particularly to a method for detecting traffic violation. The present invention includes firstly localizing vehicle salient parts through salient features including vehicle license numbers and vehicle rear lights, and representing a vehicle with the vehicle salient parts, then tracking the vehicle with a Kalman filter based on the vehicle salient parts, and finally detecting vehicle violation through moving trajectory analysis and setting violating detecting areas. The present invention solves vehicle violation detection problems in complex engineering application conditions such as illumination change and detection noise, and is suitable for city traffic management under complex conditions.

6. A method for detecting traffic violation, comprising steps of:
-
S1;
calibrating a road traffic scene;S2;
localizing all vehicle license plates in a video sequence;S3;
localizing all vehicle rear lights in the video sequence;S4;
tracking vehicles based on a plurality of vehicle salient parts, for obtaining moving trajectories of the vehicles;wherein according to a vehicle localizing result in a previous frame, a vehicle position in a current frame is predicted;
a vehicle position result in the current frame is handled as a measured value, for searching an observed value of each of the vehicles tracked through calculating an Euclidean distance between a predicted position and a measured position;
a predicted value and the observed value are calculated by weighting for updating the predicted value as a current position of an object; andS5;
analyzing the moving trajectories of the vehicles, and setting detecting areas of different violations, so as to complete vehicle violation detection. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
