ers Р, did not address the structural parameters of the system measurement accuracy. The practice proved that the structure of the system parameters in practical applications of the system's measurement accuracy is essential. In addition, from the stereo vision measurement principle, we can see the error image recognition system accuracy is another important factor in a direct impact. Based on the above considerations, the structure from the theoretical parameters of the system and image recognition errors on the precision of the system of in-depth analysis and research. Combination of system parameters on the accuracy of the camera calibration given set of practical applications, stereo vision measurement system designР1 Binocular stereo vision measurement principle and mathematical model
