| 摘 要： | 针对高速列车车顶瓷瓶定位,研究了一种基于SIFT的瓷瓶定位方法.首先分别提取瓷瓶图像和瓷瓶样本库中适应尺度变化的不变特征点,然后通过关键点的欧氏距离匹配特征点,最后得到瓷瓶特征点,正确定位瓷瓶.试验结果表明:该方法能准确定位瓷瓶,并提高了定位瓷瓶的速度.

| Abstract: | A porcelain positioning method based on SIFT was proposed.First,the scale invariant features of image and porcelain were extracted respectively,then,feature points were matched through Euclidean Distance of the key points,finally,the porcelain feature points were obtained and porcelain was positioned correctly.Experimental results showed that the method could accurately locate porcelain insulator and improve the computing speed. |
