To easily measure a vertical fitting angle of a camera mounted on a vehicle and a fitting height of the camera using a camera image photographed with the camera without reference to whether the vehicle is traveling or at a stop.SOLUTION: A measuring method comprises measuring a fitting angle and a fitting height of a camera which is mounted on a vehicle and photographs an image of a circumference of the vehicle. A measuring apparatus executes the steps of: using the camera image obtained by photographing a road surface with the camera and a model having been learnt so as to acquire a first distance between an optical axis position of the camera on the road surface and the camera; using the camera image and the model having been learnt so as to acquire a second distance between the camera and a position on the road surface having a predetermined angle of view in a vertical direction to the optical axis of the camera; and using the first distance and second distance so as to calculate a fitting angle of the camera in the vertical direction and a fitting height of the camera.SELECTED DRAWING: Figure 6

    【課題】車両の走行時でも停車時でも、車両に搭載されるカメラで撮影したカメラ画像を用いて、カメラの垂直方向の取付角度、及びカメラの取付高さを容易に測定できるようにする。【解決手段】測定方法は、車両に搭載され前記車両の周辺の画像を撮影するカメラの取付角度と取付高さとを測定する測定方法であって、測定装置が、前記カメラで路面を撮影したカメラ画像と学習済のモデルとを用いて、前記路面上の前記カメラの光軸位置と、前記カメラとの間の第1の距離を取得するステップと、前記カメラ画像と前記学習済のモデルとを用いて、前記カメラの光軸に対して垂直方向に所定の画角をなす前記路面上の位置と、前記カメラとの間の第2の距離を取得するステップと、前記第1の距離と前記第2の距離とを用いて、前記カメラの垂直方向の取付角度と、前記カメラの取付高さとを算出するステップと、を実行する。【選択図】図6
