And tracking the feature point matching method based on a motion of the vehicle speed

The present invention discloses a method based on the movement speed of the vehicle and tracking the feature point matching, belonging to the field of intelligent transportation. This method is mainly: obtaining current image sequence the Fn; obtained gray scale image of the current frame Y (n); obtained according to the present frame background modeling movement of the vehicle position information P_Cur; obtained moving object trajectory information of the current frame T; extracting features point, and the feature point information recorded; matching feature points, calculating a target displacement movement, the camera calibration results then obtain the instantaneous traveling speed of the target; the final match result is calculated scale changes to be matched feature point the feature point matching , analysis of the algorithm parameters are updated according to the analysis result; find all of the instantaneous speed of the object moving average. The present invention can be efficiently and accurately calculate the motion of displacement of the vehicle for security mount system, a red light electronic police systems and other systems.
