| 摘 要： | 提出了一种复杂表面的重构算法.算法以切片图像为输入数据，通过自由形变（free-form deformation，FFD）建立切片轮廓间的对应关系.根据相邻轮廓的拓扑关系，进行外轴投影（external axes projection，EAP）解决分叉问题.所提算法在输入源稀松、输入轮廓复杂时，仍有较高的配准度；算法高度并行，执行效率高.实验结果证明，该算法可以解决复杂表面的重构问题.

| Abstract: | A method was proposed for surface reconstruction of complex shapes. Taking slice image as input source, the corresponding relationship of upper and lower contours was established based on free-form deformation (FFD). The branching problem was converted into one-to-one case by the external axes projection (EAP). The framework could naturally deal with sparse input source and contours of arbitrary topology with high match, parallel and efficiency. Experimental results show that the approach performs can well handle complicated situations. |
