To provide a vehicle rear side monitoring system which can easily determine such a possibility that an object on the vehicle rear side collides with a vehicle from an image captured by a monocular camera.SOLUTION: A rear side monitoring system 1 comprises: a lower camera 3 which images a road surface 109 on the rear side of a truck 100; an upper camera 5 which is arranged above the lower camera 3 of the truck 100 and images the road surface 109 on the rear side of the truck 100; a conversion unit which converts a lower camera image G1 captured by the lower camera 3 into a lower bird's-eye view T1 and converts an upper camera image G2 captured by the upper camera 5 into an upper bird's-eye view T2; an object detection unit 17 which detects an object on the road surface 109 from a difference 64 of a correction part 65 that is hidden behind the object on the road surface 109 in the upper camera image G2 and the lower camera image G1 by comparing the upper bird's-eye view T2 with the lower bird's-eye view T1; and a collision possibility determination unit 19 which notifies a driver of the truck of a possibility of a collision when there is such a possibility that the object detected by the object detection unit 17 collides with the truck 100.SELECTED DRAWING: Figure 2
【課題】単眼カメラが撮像した画像から車両後方の物体が車両に衝突する可能性の判定が簡易にできる車両の後方監視システムの提供。【解決手段】トラック100の後方の路面109を撮像する下部カメラ3と、トラック100の、下部カメラ3より上方に配置され、トラック100の後方の路面109を撮像する上部カメラ5と、下部カメラ3が撮像した下部カメラ画像G1を、下部鳥瞰ビューT1に変換し、上部カメラ5が撮像した上部カメラ画像G2を、上部鳥瞰ビューT2に変換する変換部と、上部鳥瞰ビューT2と下部鳥瞰ビューT1を比較して、上部カメラ画像G2と下部カメラ画像G1では路面109にある物体に隠れていた補正部65の差分64から路面109にある物体を検出する物体検出部17と、物体検出部17が検出した物体がトラック100に衝突する可能性がある場合は衝突の可能性をトラックの運転手に知得させる衝突可能性判定部19を備える後方監視システム1。【選択図】図2
