Abstract

To improve calibration accuracy of micro stereo vision system, this chapter analyzes the calibration method based on least-square regression and parameters calibrated by weak disparity micro stereo vision model. The problem that system parameters are sensitive to noise is discovered. It can result in instable accuracy of the system. Therefore, the minimum uncertainty constraint is introduced in the calibration of the rectification parameters. It fine-tunes the magnification to realize that the two half angles and focal length in the two subsystems of stereo light microscope approximately equal each other, while the combined uncertainty is minimum. Experimental results demonstrate that the proposed calibration method is robust and effective in micro stereo vision system.
