Paper Abstract

A real-time matching method, which is used to locate an object in the binocular stereo vision system and measure the distance from the object to camera, was proposed in this paper. The 3D image is composited of one left-image and one right-image captured by the binocular cameras and is displayed in a 3D liquid crystal TV. The target is chosen by user-controlled cursor constrained in the left-image. Then, the matched point in the right-image with the current position of mouse in the left-image is detected by an effective point matching algorithm, and the right-cursor is generated on this matched point. Meanwhile the distance is calculated by the parallax between the pair points. The above algorithm was realized using the own program compiled by C sharp language. The results show that our method can match selected pixel accurately and the real-time distance measurement is realized. Moreover, our method is low-cost with little requirements for hardware.
