PROBLEM TO BE SOLVED: To display the presence of foreign matter on the basis of multiple kinds of data more quickly.SOLUTION: An image processing device 10 comprises a first acquisition unit 11, a second acquisition unit 12, a conversion unit 13, and a drawing unit 14. The first acquisition unit 11 acquires first data that represents by surface information the surface of an object located in a peripheral environment around a prescribed reference point at first point of time. The second acquisition unit 12 acquires second data that represents by point information an object surface located in the peripheral environment at a second point of time later than the first point of time. The conversion unit 13 causes at least a portion of the point group represented by the second data to shift to the depth side in the direction of a visual line extending from the reference point. The drawing unit 14 draws an object surface represented by the first data and an object surface represented by the converted second data. When the surface represented by the first data and the points represented by the second data overlap, the drawing unit 14 draws an object surface closer from the reference point than the other in the direction of a visual line.SELECTED DRAWING: Figure 4

    【課題】複数種類のデータに基づき異物の存在をより高速に表示する。【解決手段】画像処理装置10は第1取得部11、第2取得部12、変換部13、および描画部14を備える。第1取得部11は、第1の時点における所定の基準点の周辺環境に位置する物体表面を面情報で表す第1データを取得する。第2取得部12は、第1の時点よりも後の第2の時点における上記周辺環境に位置する物体表面を点情報で表す第2データを取得する。変換部13は、第2データで表される点群の少なくとも一部を、基準点から延びる視線方向の奥側にシフトさせる。描画部14は、第1データで表される物体表面と変換された第2データで表される物体表面とを描画する。第1データで表される面と変換された第2データで表される点とが重なる場合には、描画部14は視線方向において基準点から近い方の物体表面を描画する。【選択図】図4
