Calibration apparatus of on-vehicle camera, program, and car navigation system

摘要

An on-vehicle camera calibration apparatus (CA) includes: an on-vehicle camera (1); a camera parameter calculation unit (23) configured to calculate camera parameters (h', ¸', ¦', ¨') from a characteristic amount of a road surface sign photographed by the on-vehicle camera and recognized by an image processing and to output the camera parameters, wherein the camera parameters include the installation height (h') and installation angles (¸',¦',¨') of the on-vehicle camera in photographing; and a camera parameter calibration unit (25) configuredto perform optical axis calibration control of the on-vehicle camera by the camera parameters output from the camera parameter calculation unit.
