Road detection is an important part of the intelligent transportation vision system, according to the current problems of real-time, accuracy, robustness for unstructured road detection in complex environment, a new method is proposed for road detection. The means compresses data information of image through Gaussian pyramid down-sampling process and adopts bilateral filtering to suppress noise, then extracts edges of the filtered images based on modulus maximum of wavelet transform, uses threshold method to remove non-road edge points. A new K-means clustering algorithm is proposed which is based on slope and intercept, and it realizes road equation fitting. Experimental results show that this method can realize unstructured road detection more accurately in complicated road scene and improve real-time than traditional methods.
