| 摘 要： | 针对色盲或色弱驾驶员特殊群体,结合交叉口无人驾驶系统,提出一种能识别出交通信号灯当前状态的方法。在HIS颜色空间进行交通灯颜色分割,利用交通灯被黑色矩形框包围这一典型特征进行形状分割,根据形状分割所得位置对颜色分割候选区域进行确认,从而精确定位交通灯位置以及亮灯在交通灯中的位置;同样根据被黑色矩形框包围的特征设计模板,最终利用模板匹配,完成交通灯的识别。实验表明,该算法识别准确率较高。

| Abstract: | In this paper,a method of recognizing traffic lights through image processing is proposed.The system can help the visual impaired people driving through the signalized intersections.First,certain regions in an image are selected as color candidates from HIS color space.Then,based on the typical shape of traffic lights-black rectangular box,the algorithm will segment the image and select shape candidates.According to the position of candidate color segments and candidate shape segments,the position of traffi... |
