To provide a technique for suppressing false recognition of a calibration result in verifying calibration of a camera.SOLUTION: A calibration verification method for verifying a calibration result of a camera mounted on a vehicle includes: an image acquiring step S103 of acquiring a photographed image obtained by photographing, with the camera, a state where a verification target with one or more marks put at predetermined heights is arranged around the vehicle; an overlay position calculation step S105 of calculating a display position of a required accuracy range representing a required accuracy of the camera corresponding to a height of a mark, based on positional information of the verification target and the required accuracy of the camera; overlay image creation steps S106-S108 of creating an overlay image indicating the display position of the required accuracy range, and causing a display device to display a verification image created by overlaying the overlay image on the photographed image; and a verification step S111 of determining that a calibration result of the camera satisfies the required accuracy of the camera when the mark of the verification target is displayed within the required accuracy range in the verification image.SELECTED DRAWING: Figure 7

    【課題】カメラの校正確認に際して校正結果の誤認を抑制し得る技術を提供する。【解決手段】車両に搭載されたカメラの校正結果を確認する校正確認方法であって、所定の高さに1以上の目印が付された確認ターゲットが車両の周囲に配置された状態をカメラにより撮影した撮影画像を取得する画像取得ステップS103と、確認ターゲットの位置情報およびカメラの要求精度に基づいて、目印の高さに対応するカメラの要求精度を表す要求精度範囲の表示位置を計算する重畳位置計算ステップS105と、要求精度範囲の表示位置を示す重畳画像を作成して、撮影画像に重畳画像を重畳した確認画像を作成し、表示装置に表示させる重畳画像作成ステップS106~S108と、確認画像において確認ターゲットの目印が要求精度範囲内に表示されている場合に、カメラの校正結果がカメラの要求精度を満たすと判定する確認ステップS111と、を含む。【選択図】 図7
