Compensation System of Stereovision Geometry

摘要

This paper describes compensation algorithm of Stereovision geometry. To analyze three-dimensional position using Stereovision, we must calibrate geometrical relation between the cameras. But, when it is used in the vehicle, aging of the equipment breaks calibrated relation. In this case, we must calibrate it again. But this process is very inefficient. So, we propose automatic compensation algorithm of Stereovision geometry. This algorithm has the feature that there is no need to prepare the special equipment and image. In this paper, we show compensation technique and the experiment construction system. Moreover, it is checked that the validity of the compensation system.
