摘　　要：随着交通智能化和智能车技术的发展,智能车对道路目标的识别成为智能车辆研究的一个重点问题。文中首先对道路图像进行了二值化处理、空间域平滑处理和边缘检测,使道路中如道路边沿、道路标线、导向标志的大致区域得到了初步认定,然后分析了道路导向标志的影像、形状等特征,利用数学形态学方法进行了初步识别,最后研究了基于链码特性的道路导向标志目标检测算法,实现了导向标志目标的初步识别和检测。With the development of intelligent transportation and intelligent vehicle technology,identification of the road target becomes a key problem in the research of intelligent vehicle.In the first part of the paper road image has carried on binarization processing,spatial smoothing and edge detection,the road such as road edge,roughly the area of road marking,signs have been identified.Then the images of road signs guide,shape and other characteristics are analyzed,mathematical morphology road sign image is used to guide a preliminary identification.The final study guides road signs target detection algorithm based on chain code features to achieve the initial target identification and detection of the guide signs.
