This paper improves the accuracy of fisheye stereo camera by correcting images using a disparity offset map. A disparity offset map is a map of disparity errors that are calculated from the disparity of the feature points obtained from an object with known distance. By correcting the disparity errors and aligning the images, errors due to the insufficient calibration of the camera parameters, etc. are reduced. A disparity offset map is constructed and the accuracy of distance measurement of a fisheye stereo camera using the disparity offset map is evaluated by experiments.
