中文摘要：

提出了一种在ROI（Region Of Interest）即感兴趣区域中建立搜索窗口的新的车道识别算法，使其能够更好的处理非理想路况的各种不确定因素，并建立实时动态的搜索带，除了能更精确的追踪车道标志线之外，还能更好的应用于弯路路况。由于ROI的建立，整个识别过程的计算量大大降低。因此更适合实时要求。

英文摘要：

The paper bring forward a new road detection arithmetic which set search windows in ROI （i.e. Region Of Interes） ,this arithmetic can dispose every kinds of uncertainty factors very well on road surface if the road surface condition is not favorably, and set real time dynamic search strip in ROI, besides it can tracking lane more accurately, this arithmetic also can be applied in crooked road condition very well. As the setting of ROI, the compute of search process can be reduced greatly, so it is more fit for the requirement of dynamic.
