Abstract
A calibration device for calibrating ranges obtained by a range-finding system includes an image acquisition unit to receive inputs of two reference images captured by a reference imaging device at two locations and multiple items of parallax data from the parallax calculator. The calibration device includes a feature point search unit to search for multiple reference-feature points common to the two reference images, and a coordinate converter to convert coordinates of the two items of parallax data based on the multiple feature points and the multiple corresponding points. The calibration device includes a correction value calculator to calculate a correction value to correct the range measured by the range finding system, based on a converted parallax from the coordinate converter.
