Abstract
The present invention relates to a large-range-first cross-camera visual target re-identification method. The method comprises: step S, obtaining initial single-camera tracks of targets; step S, calculating a piecewise major color spectrum histogram feature of each track, and obtaining a track feature representation; step S, obtaining a calculation formula of the similarity between any two tracks by using a minimum uncertainty method, so as to obtain the similarity between any two tracks; and step S, performing global data association on all the tracks by using a maximum posterior probability method, so as to obtain a cross-camera tracking result. The target re-identification method of the present invention achieves high correct identification accuracy.
