摘要
根据旋转曲面的几何特性,提出了一种基于单幅图像,采用轮廓线进行旋转曲面重建的方法。该方法通过获取旋转体的对称轴,并结合旋转体的边缘曲线及其特征点信息,实现了旋转曲面的三维重建。实验结果表明,通过使用该方法可以根据旋转体的二维图像方便的重建出其三维形状。该方法在文物保护、考古、工业测量等领域具有很高的实用价值。
According to the geometrical characteristics, a method which based on single image and adopt the contour lines to complete the reconstruction of the rotated curved surface is proposed. The method acquires the axis of rotated object, and combines the two brim curves and characteristic points of the rotated object to realize the 3D reconstruction of rotated surface. The experiment indicates that the method could conveniently reconstruct the 3D shape of the rotated object according to its 2D image. The method has extensive practical value in the areas such as the protection of cultural relics, archeology, technical meterage and so on.
