ABSTRACT:
A calibration device for calibrating a range image sensor, detecting a distance of each direction within a detection range and generating a range image data, in a state where the range image sensor is attached at a mobile body, the calibration device includes a data receiving portion for receiving a calibration-subject data including a calibration target, which is set within the detection range and includes a first plane surface and a second plane surface, from the range image sensor, a plane surface specifying portion for specifying each of the first and second plane surfaces in a three-dimensional reference coordinate system, a normal vector calculating portion for three-dimensionally calculating a normal vector of each of the first and second plane surfaces, and a rotation calculating portion for three-dimensionally calculating a rotation of the range image sensor on the basis of an already-recognized posture information and the normal vector.
