Paper Abstract

Computer vision method is an important technology for non-contact and non-destructive measurement. A lot of research is focusing on the 3D vision technique. Shape from stereo is the most popular method because it can provide high accuracy and high exactness measurement result. But if the surface is complex, the measurement result is always poor. So how to make sure the 100% stereo matching rate is an important task for the development of shape from stereo method. A novel strip matching method, which can ensure 100% matching accuracy, is proposed in this paper. It doesn't need any other assistant symbol or flag. The proposed dichotomy strip matching method is proved to a technique which high precision, low costs, easy operation, and an automatically matching method. Furthermore, it can be widely used in most of 3D vision recovery systems.
