PROBLEM TO BE SOLVED: To provide a parking support device which accurately detects a traverse white line at a rear end of a parking frame, and a traverse line detection method of the parking frame.SOLUTION: A parking support device comprising imaging means and traverse line detection means comprises: vehicle moving means; and traverse line determination means which includes that a traverse line is moved on an image accompanied by the movement of a vehicle. In the parking support device, a stripe resulting from light which is emitted from a rear lamp is set so as to be in a vehicle traverse direction, the traverse line detection means determines the traverse line when the luminance of the traverse line is higher than a threshold, and the threshold is a value higher than the luminance of the stripe, and lower than luminance which is obtained by adding the luminance of the lightest traverse line out of traverse lines of the parking frame to the luminance of the stripe. Furthermore, a traverse line detection method of the parking frame determines the traverse line of the parking frame in the case that a preset condition is satisfied, and the condition includes that the movement of the traverse line is detected on the image accompanied by the movement of the vehicle.SELECTED DRAWING: Figure 1
【課題】本発明は、駐車枠後端の横白線を精度よく検出する駐車支援装置及び駐車枠の横線検出方法を提案することを目的としている。【解決手段】このため、撮像手段と横線検出手段とを備えた駐車支援装置において、車両移動検出手段と、車両の移動に伴って横線が画像上で移動したことを含む横線判定手段とを備える。また、駐車支援装置において、バックランプから出射される光に起因する縞が車体横方向になるように設定して、横線検出手段は横線の輝度がしきい値よりも大きい場合に横線と判定し、しきい値は縞の輝度よりも大きい値であるとともに、駐車枠の横線の中で最も薄い横線の輝度と縞の輝度とを加算した輝度よりも小さい値である。更に、予め設定された条件を満たす場合に駐車枠の横線であると判定する駐車枠の横線検出方法であって、車両の移動に伴って画像上で横線の移動が検出されたことを条件として含む。【選択図】図1
