摘要
智能交通系统是近年来国内外广泛关注的研究课题,在基于计算机视觉系统的交通标志识别中,关键步骤之一是如何快速有效地检测并提取交通标志。该文提出了基于色彩的指示标志检测与提取的快速有效方法。它包括:对实景图像进行色调不变的彩色增强,彩色聚类,形态滤波,模板匹配,特征点判别等步骤。最后,由搜索到的特征点从增强后的彩色图像中抽取指示标志。实验显示该方法能快速有效地从实景图像中检测指示标志。
In recent years, intelligent transportation system becomes a topic being widely interested.How to detect traffic sign from scene is a key step in traffic sign recognition system based on computer vision.This paper proposes an effective method for detecting indicatory signs in color image.The method includes color enhancing with. hue-invariance,color clustering, morphological filtering,pattern matching,feature judging. Finally,the traffic sign is extracted from the enhanced color image.Experimental results show that the proposed method can detect indicatory signs quickly and efficiently.
