DIFFERENCE DETECTION PROGRAM, DIFFERENCE DETECTION DEVICE, AND DIFFERENCE DETECTION METHOD
PROBLEM TO BE SOLVED: To adequately detect a difference between point group data.SOLUTION: The difference detection program allows a computer to perform processes of: acquiring a first point group and a second point group which are created based on a plurality of different captured images, specifying color information of a point included in a first region of the first point group and color information of a point included in a second region of the second point group corresponding to a position of the first region, and when it is detected that a difference between the color information of the point included in the first region and the color information of the point included in the second region is equal to or larger than a threshold value, providing an output according to the detection result for the first region or the second region.SELECTED DRAWING: Figure 1
【課題】点群データ間の差分を適切に検知することを目的としている。【解決手段】それぞれ異なる複数の撮像画像に基づいて作成された第１の点群と第２の点群とを取得し、前記第１の点群の第１の領域に含まれる点の色情報と前記第１の領域の位置に対応する前記第２の点群の第２の領域に含まれる点の色情報とを特定し、前記第１の領域に含まれる点の色情報と前記第２の領域に含まれる点の色情報との差分が閾値以上であることを検知すると、前記第１の領域又は前記第２の領域について前記検知の結果に応じた出力をする、処理をコンピュータに実行させることを特徴とする差分検知プログラムである。【選択図】図１
