The stereo vision systems are highly used for 3D depth reconstruction. The measurement accuracy of these scanners affected by the quantization error caused by the camera sensors. In this paper, the effect of changing the convergence angle of the cameras on the quantization uncertainty is discussed. Firstly, the mathematical model of a stereo vision scanner with the ability of adjusting the convergence angle was introduced. Then, the effect of changing the convergence angle on the quantization error reduction was investigated. Finally, the physical experiments were designed to validate the proposed approach. The experimental results showed that the 3D reconstruction accuracy can be improved by changing the convergence angle of the cameras.
