The Technology Measuring Of Three Dimension Position Based On Computer Vision

With the development of the computer hardware and the theory of vision, the technology of computer vision is applied to industry gradually; the 3D measurement based on computer vision has become an important part in the measurement field.In the application of computer vision, it is difficult to improve the precision and the stability during the camera calibration.This paper which based on the research of the existing camera calibration methods, analyze their precision and stability and bring forward an improved step-by-step camera calibration method and a camera calibration method based on image revision.The two methods reach a good combination on the stability and precision.This paper also research the stereo matching method, and synthesize all parts of the technology to bring forward an implement of the 3D measurement system based on the computer vision.Zhang Dongsheng(Control Theory and Control Engineering) Directed by Yang Yaoquan...
