PROBLEM TO BE SOLVED: To suppress reduction in accuracy in mapping of the same object imaged by a plurality of imaging devices.SOLUTION: An image processing program extracts a region excluding a region shielded by a shield material of a whole region as a specific region of an object when a part of the object detected from an image imaged by a plurality of imaging devices is shielded; calculates a region ratio of the specific region in an area of the whole region and a relative position of the specific region corresponded to the whole region; calculates a first similarity level of the specific region of an object of a processing target and an object of a comparison target by using a specific amount of the specific region of the target of the processing target and a specific amount of the specific region of the target of the comparison target; combines a plurality of specific regions of the object of the processing target on the basis of the region ratio and a relative position; calculates a second similarity level as a whole similarity level with the object of the processing target and the object of the comparison target on the basis of each region ratio and the first similarity level of the specific region to be combined; and allows a processing for corresponding the same objects to execute by a computer on the basis of the second similarity level.SELECTED DRAWING: Figure 1 【課題】 複数の撮像装置で撮像された同一の対象物の対応付けの精度の低下を抑制する。【解決手段】 画像処理プログラムは、複数の撮像装置で撮像される画像から検出した対象物の一部が遮蔽される場合、全体領域のうちの遮蔽物で遮蔽される領域を除く領域を対象物の特徴領域として抽出し、特徴領域が全体領域の面積に占める領域割合と、全体領域に対する特徴領域の相対位置とを算出し、処理対象の対象物の特徴領域の特徴量と比較対象の対象物の特徴領域の特徴量とを用いて、処理対象の対象物と比較対象の対象物との特徴領域の第１類似度を算出し、処理対象の対象物の複数の特徴領域を領域割合と相対位置とに基づいて組み合わせ、組み合わせた特徴領域の各々の領域割合と第１類似度とに基づいて、処理対象の対象物と比較対象の対象物との全体の類似度として第２類似度を算出し、同一の対象物を第２類似度に基づいて対応付ける処理をコンピュータに実行させる。【選択図】 図１
