PROBLEM TO BE SOLVED: To effectively perform calibration of an imaging camera for capturing a rearview image of a vehicle in a manufacturing process in a factory.SOLUTION: A camera calibration device comprises: a calculation unit for calculating homography on the basis of coordinates of calibration indices in a reference image in which one or a plurality of calibration indices are captured and coordinates of calibration indices in a captured image in which one or a plurality of calibration indices are captured by a first imaging camera having a wide angle lens or a fisheye lens from the rear of a vehicle; and a calibration unit for correcting the captured image captured by the first imaging camera on the basis of the homography.SELECTED DRAWING: Figure 2
【課題】工場等の製造工程において、車両の後方の画像を撮像するための撮像カメラの校正を、効率的に行うこと。【解決手段】カメラ校正装置は、一または複数の校正指標が撮像された基準画像における校正指標の座標と、広角レンズまたは魚眼レンズを有する第1撮像カメラで一または複数の校正指標を車両の後方から撮像した撮像画像における校正指標の座標とに基づいて、ホモグラフィを算出する算出部と、ホモグラフィに基づいて、第1撮像カメラで撮像された撮像画像を修正する校正部と、を備える。【選択図】図2
