摘要：

针对现有盲道识别率低,处理方式单一,且容易受光照、阴影的影响等问题,提出一种改进的盲道识别算法。该方法针对盲道颜色、纹理特性,分别利用颜色直方图特征的阈值分割结合改进的区域生长分割,灰度共生矩阵特征的模糊C均值聚类分割,结合Canny边缘检测和Hough变换算法,使得盲道区域与周围人行区域分开,确定出盲道的偏移方向。实验结果表明,该算法能够更加精准地分割多种类型盲道,检测出盲道区域的边界与行进方向,而且解决了部分光照和阴影问题,能够自适应选择速度最快而且高效的分割方法,可以应用在电子导盲等多种设备中。

Abstract:

Concerning the problem that existing blind road recognition method has low recognition rate, simplistic handling, and is easily influenced by light, or shadow, an improved blind road recognition method was proposed. According to the color and texture features of blind road, the algorithm used two segmentation methods respectively including color histogram feature threshold segmentation combined with improved region growing segmentation and fuzzy C-means clustering segmentation for gray level co-occurrence matrix feature. And combined with Canny edge detection and Hough transform algorithm, the proposed algorithm made the blind area separated from the pedestrian area and determines the migration direction for the blind. The experimental results show that the proposed algorithm can segment several kinds of blind road more accurately, detect the boundary and direction of blind road and solve the light and shadow problem partly. It can choose the fastest and the most effective segmentation method adoptively, and can be used in a variety of devices, such as electronic guide ones.
