本文提出了对道路标志进行快速别的一种辅助系统,该系统以人类的视觉及思维模式作为蓝本,可以较为快速的实现行进汽车中的交通标志识别。这一系统通过安装在汽车上的摄像机获取信息,通过子采样消除图像重影同时减少需要处理的数据量,然后根据交通标志的色彩和形状两方面特征,寻找画面帧中的交通标志,采用模板匹配的方法实现标志的定位和最终识别。关键词:道路标志;识别;图像处理Abstract:A new Road Sign Recognition system is designed to support quick survey of traffic signs. The image acquisition is based on a digital camera equipped on vehicle. Furthermore, the system use subsampling to eliminated the interlace. For the detection, color thresholding is used to segment the image and shape analysis to detect the signs. Recognition is done by matching the extracted features with previously stored features of standard signs.Key words:road sign,recognition,image processing
