Effects of camera alignment errors on stereoscopic depth estimates

摘要

We present in this paper a new analysis of relative sensitivity/importance of camera calibration/alignment parameters on the performance of stereoscopic depth reconstruction. This quantitative analysis provides formulae which relate different parameter errors to the 3-D reconstruction measurements. The results of this analysis provide specifications of acceptable tolerances in individual calibration parameters for given 3-D measurement error tolerances. This information is useful in designing practical stereoscopic vision systems.
