Abstract:

In order to ensure that vehicles go through winding roads safely and effectively,accurate identification of the bend curvature is particularly important.Therefore,this article proposes a technology of identifying winding roads based on wavelet decomposition.This algorithm collects the real-time road images with vehicle-mounted CCD.The wavelet of the collected images is then de-noised and its edge detected.Finally the lane's line is accurately identified.The curvature radius is determined through curve fitting.Experiments show that this algorithm can accurately identify the curvature radius of the winding roads.

Key words: corners to identify;wavelet decomposition;curve fitting
