Abstract
A positional deviation adjusting apparatus of a stereoscopic camera includes a correction circuit for transforming images geometrically according to transformation parameters and a calculating section. A plurality of reference areas are established on a reference line of one image and a reference point is established for every reference area. The calculating section identifies correlation points having a correlation with the respective reference points in the other image. Further, the calculating section calculates an approximation line based on the correlation points and corrects the transformation parameters in such a manner that the approximation line coincides with the reference line.
