DEDUCTION OF CONSTRAINT CONDITIONS IN THE CALIBRATION OF STEREO-VISION SYSTEM

In the test-field calibration, multi-azimuth stereo image pairs are produced of the outdoor large control-field by the stereo-vision system under calibration. While in the analytical processing, the relationship between image pairs is adopted as a constraint condition, which ensures the stability and quality of the calibration results. This paper introduces the deduction process of the constraint conditions.
