Abstract
Provided is a calibrating apparatus for an on-board camera of a vehicle, which apparatus allows completion of calibration process with a simple additional calibration, even when rejection has issued on the result of automatic calibration. Based upon a camera parameter obtained at the time of completion of adjustment by an automatic adjusting section, a confirmation marker indicating the position of coordinate of a calibration point is displayed in superposition with a camera-captured image. A manual adjusting section adjusts the camera parameter, based on an amount of displacement of the coordinate of the calibration point corresponding to an amount of movement of the confirmation marker moved in response to input of adjustment instruction. In response to input of a determination instruction, a camera parameter setting section sets an undetermined camera parameter at the time of completion of the most recent adjustment by the automatic adjusting section and the manual adjusting section, as the camera parameter.
