| 摘 要： | 根据原木端面图像的获得方式及其特性,改进了方向链码的轮廓跟踪技术,提出了从图像中心点开始竖直往下扫描获取跟踪起始点,并在约束条件下自动寻找端面图像目标轮廓的算法,此算法大大提高了原木端面图像的轮廓跟踪效率.原木端面为类圆形图像,根据获得的目标轮廓的链码序列和边界点的坐标信息,提出了确定原木端面图像目标轮廓的圆心及最短径等一系列检尺参数的方法.

| Abstract: | According to the method of getting the logs images and their characteristics,the paper improves the eight-direction chain code contour tracking technology.Present an algorithm which beginning from the center point of the image,scan down vertically to get the start point of the contour tracking,and find the target outline automatically with a constraint condition.The experimental results prove that the algorithm works efficiently.Based on the chain code sequence of the target outline and the coordinate infor... |
