快速提取旋转体轮廓母线方法

为重建出旋转体的三维形态，提出了一种基于单幅图像实现旋转体母线和对称轴的提取方法。该方法主要利用工业摄像机获取目标物体的二维图像，在图像预处理中，针对拍摄原因产生的倾斜图像给出了一种几何矫正方法，利用目标区域的轮廓特征提取旋转体的母线信息，结合旋转体轮廓曲线的左右对称性求得目标物体的对称轴。并以陶瓷文物花瓶为目标，实现了旋转体母线及对称轴的提取，最后重建出目标的三维形态。实验证明了该方法的有效性。

Fast Extraction Method of Bus Line Based on Body Contour

In order to reconstruct the three-dimensional shape of the rotating body，a single image is proposed to achieve the extraction of the rotating body bus and the symmetrical axis． This method is to obtain two-dimensional image by using industrial camera． In the image preprocessing，the image shooting causes tilt，and we gives a geometric correction method，bus information extraction of rotating body using the contour feature of target area，combined with the symmetry axis of symmetry around the rotating body contour curve to obtain the target object． With the aim of ceramic vase，the extraction of the bus and symmetry axis of the rotating body is finally realized，and the three-dimensional shape of the target is rebuilt． The experiment proves the effectiveness of the proposed method．
