基于轮廓线的旋转体三维重建

由旋转体的二维灰度图像恢复其三维形状已经成为计算机视觉领域的一个研究热点.对该问题进行了深入的研究,提出了一种基于单幅图像,采用轮廓线特征信息进行旋转体重构的方法.该方法从一幅二维灰度图像中提取旋转体作为研究对象,通过角点检测方法获取有效轮廓线及其分段曲线,根据分段曲线类型及其特征信息构造旋转体的对称轴,结合旋转体的几何特性实现了旋转曲面的三维重建.实验证明,该方法可以根据旋转体的二维灰度图像方便有效地重建出其三维形状.

Three-dimensional Reconstruction of Rotated Object Based on Contour Lines

Three-dimensional reconstruction from two-dimensional grey image of rotated object has been a research hot spot in the filed of computer vision.Based on the deep research on it,a method was proposed which applied message feature of contour lines from single image to reconstruct rotated object.The method extracted the rotated object as the research target,adopted corner detection to acquire valid contour lines and their sub-curves.Then it acquired the axis of rotated object according to the type of sub-curves and information of characteristic points and combined the geometric properties of rotated object to realize the three-dimensional reconstruction of curved surface.The experiment indicates that the method can conveniently reconstruct the three-dimensional shape of the rotated object according to its two-dimensional grey image.
