To prevent an erroneous distance from being calculated.SOLUTION: A processing part 1a of an information processing device 1 acquires photographic images 11, 12 photographed by a camera 2 installed on a first movable body. The processing part 1a detects a second movable body (a vehicle 13 in the example of Fig. 1) from the photographic images 11, 12, and detects a shield region 14 reflected at a lower side in the photographic images 11, 12 to shield a portion of the road region. The processing part 1a determines whether a prescribed condition showing that at least a portion of lower sides 15a, 16a of circumscribed rectangles 15, 16 that circumscribe a second movable body overlaps or is adjacent to the shield region 14 is satisfied, on the basis of detection results of the second movable body and the shield region 14. The processing part 1a calculates a distance between the first movable body and the second movable body on the basis of coordinates of reference points 15b, 16b on the lower sides when the prescribed condition is not satisfied, and skips distance calculation processing when the prescribed condition is satisfied.SELECTED DRAWING: Figure 1

    【課題】誤った距離が算出されることを防止する。【解決手段】情報処理装置1の処理部1aは、第1移動体に設置されたカメラ2が撮影した撮影画像11,12を取得する。処理部1aは、撮影画像11,12から第2移動体(図1の例では車両13)を検出し、撮影画像11,12において道路領域の下側に写り、道路領域の一部を遮蔽する遮蔽領域14を検出する。処理部1aは、第2移動体および遮蔽領域14の検出結果に基づいて、第2移動体に外接する外接矩形15,16の下辺15a,16aの少なくとも一部と遮蔽領域14とが重複または近接することを示す所定条件が満たされるかを判定する。処理部1aは、所定条件が満たされない場合、下辺上の基準点15b,16bの座標に基づいて第1移動体と第2移動体との間の距離を算出し、所定条件が満たされる場合、距離の算出処理をスキップする。【選択図】図1
