摘要：

Aiming at the problem of binocular vision system in three-dimensional coordinate measurement of remote target point. First, this article analyzes the main error sources of camera calibration and three-dimensional positioning process in binocular vision arc analyzed based on the principle of binocular vision measurement system. Then, derivative relations between binocular vision three-dimensional positioning measurement system and camera parameters, matching accuracy of feature points, pixel size, focal length, baseline length and measurement distance arc derived. Finally, the influence of each parameter on the positioning error of the measurement system is obtained through the simulation experiment. The experimental results show that the error model has a certain guiding significance for the design of binocular vision measurement system.
