In vehicle tracing and locating, character points matching in stereo vision algorithm has more calculation works, high error matching probability and can not run in real time. In this paper, the technology of character points matching is studied. After compared several matching algorithms, we put forward a method named rectangle constraint of color field matching. The experiment results show that the method has 100% matching accuracy, quickly calculating rate and strong adaptability.
