Research on road detection based on blind navigation device

摘要

This paper presents a method of structured road lane detection for blind travel aid; Median Filter is implemented to process image firstly, then mark off the region of interesting in the initial image, Canny edge enhancement, threshold is used to segment the image, road lane is fitted by modified Hough Transformation. Finally, according to the detected region to judge whether racing course of bind has a deviation. The experimental results prove this algorithm is very robust and real-time.
