利用双三次均匀Ｂ样条曲面片建立三维光学数字图像的逼近模型。该数学模型是依据双三次均匀Ｂ样条曲面片对三维光学数字图像的分片逼近技术来建立的。文中给出了空间自由表面的双三次均匀Ｂ样条表达方法和三维数字像的Ｂ样条重构结果。
Approximation Model of Three Dimensional Optical Digital Images Based on Bicubic B-spline Surfaces. The mathematical model is based on the bi-cubic uniform B-spline patches for the three-dimensional optical digital image segmentation approximation technology to establish. In this paper, the bi-cubic uniform B-spline representation of the free surface of the space and the B-spline reconstruction result of the three-dimensional digital image are given.
