To provide a "rear view image display system" to display a tractor's rear view image with less blind corners naturally.SOLUTION: A rear view image display system is configured to: replace regions of a region hidden by a trailer 1 in a rear view image b captured by a tractor rear camera 215 located at a rear side of a tractor 2, the regions including a scene viewed by the tractor rear camera 215, the scene being captured by a side camera of the trailer 1 without being hidden by the trailer 1, by video c1, c3 obtained by converting viewpoint of video captured by the side camera into a viewpoint of the tractor rear camera 215; and replace remaining regions including a scene viewed by the tractor rear camera 215 and captured by a rear camera of the trailer 1 without being hidden by the trailer 1, by video c2 obtained by converting viewpoint of video of the rear camera of the trailer 1 into a viewpoint of the tractor rear camera 215, to generate rear video d to be displayed. Each region is calculated based on a detected hitch angle of the trailer 1.SELECTED DRAWING: Figure 6
【課題】死角少なく自然な形態で牽引車後方の映像を表示する「後方映像表示システム」を提供する。【解決手段】牽引車2の後部の牽引車後方カメラ215で後方を撮影した映像b中の、トレーラ1によって遮蔽されている領域の部分のうち、牽引車後方カメラ215から見た、その部分の方向の様子がトレーラ1の側部のカメラでトレーラ1に遮蔽されることなく撮影される部分は、側部のカメラの映像を牽引車後方カメラ215の視点に視点変換した映像c1、c3で置換し、残る部分のうちの、牽引車後方カメラ215から見た、その部分の方向の様子がトレーラ1の後部のカメラでトレーラ1に遮蔽されることなく撮影される部分は、トレーラ1の後部のカメラの映像を牽引車後方カメラ215の視点に視点変換した映像c2で置換して、表示する後方映像dを生成する。各領域は、検出したトレーラ1のヒッチ角に基づいて算定する。【選択図】図6
