PROBLEM TO BE SOLVED: To detect the tilt of an imaging direction on the basis of image data acquired by an imaging device.SOLUTION: An image processing device 100 comprises an acquisition unit 151, an extraction unit 152, and a detector 153. The acquisition unit 151 acquires image data of each frame number from a drive recorder etc. The extraction unit 152 extracts plural straight lines from the image data on the basis of drive recorder information 141. The detector 153 detects the tilt of the imaging direction of a camera in response to the angles formed with the extracted lines.

    【課題】撮像装置により取得された画像データに基づき、撮像方向の傾きを検出すること。【解決手段】画像処理装置100は、取得部151と、抽出部152と、検出部153とを有する。取得部151は、ドライブレコーダ等から、フレーム番号毎の画像データを取得する。抽出部152は、ドラレコ情報141を基にして、画像データから複数の直線を抽出する。検出部153は、画像データの縦軸方向と、抽出した複数の線とのなす角の大きさに応じて、カメラの撮像方向の傾きを検出する。【選択図】図1
