Improving the selection quality of the region of interest is an effective way to improve the real-time and accuracy of lane detection. This paper introduces the common methods of Region Of Interest (ROI), including four methods of Region extraction based on fixed proportion, fixed Region, vanishing point and gray mean of row, and analyzes the implementation methods. The comparison shows that, The four methods listed have obvious differences in adaptability to different environmental disturbance factors, and the application scenarios of different ROI extraction methods are given for reference by relevant scholars. Finally, the research of ROI extraction method is prospected.
