白線エッジ特徴を考慮したエッジ重畳による道路白線抽出

抄録

The objective of this study is to reduce rear-end vehicle collisions caused by human errors. In order to achieve this objective, we studied a technique to detect preceding vehicles with image processing using a monocular in-vehicle camera and a computer. As an image characteristic for vehicle detection, we adopt the shadow under the vehicle. Furthermore, in order to detect the shadow with high precision, limiting the processing area based on the white line detection. In this paper, we propose a technique for the white line detection by “edge detection using the white line edge characteristics” and “edge overlay using the ring buffer”. Experimental results show that the proposed method is more effective than the previous method.
