摘要:

为了保障车辆安全有效的通过弯道,准确识别弯道曲率尤为重要。因此,文中提出一种基于小波分解的弯道识别技术,该算法通过车载CCD实时采集自车前方的车道线的图像信息,对采集的图像进行小波去噪以及小波边缘检测,最终准确辨识车道线,通过曲线拟合确定道路的曲率半径。经试验验证,该算法能准确辨识出弯道的曲率半径。

关键词: 弯道识别, 小波分解, 曲线拟合

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
