Abstract
Provided is a calibration device that can calculate the mounting state of a stereo camera without the placing of a physical marker. In this device, an area setting processor () preliminarily sets, for an integrated image in which a road surface image region and a setting-prohibited region are integrated, an arrangement pattern having a plurality of area setting frames, and adjusts the arrangement pattern so that the plurality of area setting frames recede from each other. An extraction processor () extracts from distance images a plurality of partial images corresponding to the plurality of area setting frames. A mounting-state calculation unit () calculates a mounting-state parameter on the basis of a plurality of partial images, such parameter relating to the mounting state of a stereo camera used to pick up stereo images.
