| 摘 要： | 图像定位是图形图像学研究的重要方面,然而较慢的定位速度一直制约图像定位的实时应用。文章探讨了一种图像投影的快速定位算法,将二维图像信息的特征压缩成一个特征向量,将该特征向量作为定位的参数进行图像定位,大大提高了定位的速度。该算法比一般的相关算法、快速傅立叶算法具有非常明显的速度优势;并且将基于该算法的图像定位系统嵌入到二维移动工作台进行实时实验,取得了很好的实验结果。

| Abstract: | Locating algorithm is one of the important parts of image study,however its low velocity handicaps the application in real-time situation.A fast algorithm,which is based on the projection of image,compresses the characters of two-dimension image into a vector,then the time is reduced by using this vector for locating. This algorithm has superiority in velocity compared with common correlation algorithm and FFT algorithm.We have achieved satisfying experimental result by embedding the algorithm into two-coordinate moving worktable to have real-time tests. |
