To suppress degradation in calculation accuracy of a deviation amount following a state change of environmental light.SOLUTION: A deviation amount detection method comprises the steps of: making an illumination device 10 irradiate a structure 2 of a vehicle with light for suppressing influence of environmental light being light that enters the vehicle from the outside of the vehicle; making an imaging device 1 image the structure 2 irradiated with the light by the illumination device 10; and making a deviation amount detection device 3 calculate a deviation amount between the installation position of the imaging device 1 and the correct installation position of the imaging device 1 on the basis of the image of the structure 2 imaged by the imaging device 1.SELECTED DRAWING: Figure 1

    【課題】環境光の状態変化に伴うずれ量の算出精度の劣化を抑えることができるようにする。【解決手段】照明装置10が、車両の外部から車両内に入ってくる光である環境光の影響を抑制するための光を車両の構造物2に照射する工程と、撮像装置1が、照明装置10によって光が照射されている構造物2を撮影する工程と、ずれ量検出装置3が、撮像装置1により撮像された構造物2の画像に基づいて、撮像装置1の設置位置と、撮像装置1の正しい設置位置とのずれ量を算出する工程とを備えるように、ずれ量検出方法を構成した。【選択図】図1
