Abstract: Lane line is an important part of the high definition(HD) map. This paper discusses the method of lane line extraction using high resolution remote sensing image. According to the histogram principle, the appropriate threshold is selected for binarization segmentation, the buffer formed by the road center line is used to remove the elements outside the range of the road, and the morphological operator is used to remove the noise. Shape and direction feature used to distinction lane line. This method can reduce the cost of data collection and improve the efficiency of data collection.

Key words: high definition(HD) map, lane line, high resolution, remote sensing image, self-driving
