| 摘 要： | 提出一种基于相位信息与边缘投影的车体定位新算法,先将RGB颜色模型与HSV颜色模型相结合,利用相位一致性检测出汽车图像中的车体边缘,再通过投影处理得到候选车体区域,然后对候选区域进行判别,最终得到车体的精确位置.实验结果表明,该算法鲁棒性强,受图像亮度、对比度和阴影的影响小,而且适用于包含多部车辆的图像,定位准确率高于其他常用算法.

| Abstract: | A novel vehicle localization algorithm based on phase information and contour projection is proposed.Firstly,HSV color model and RGB color model are combined,and contours of the vehicles in image are detected based on phase congruency.Secondly,contour projection method is utilized to get candidate vehicle regions.Finally vehicle region distinguishing algorithms are applied to the candidates,and the exact positions of vehicles are obtained.Experiment results show that the new algorithm has strong robustness ... |
