There are two key techniques in reverse engineering, the numeralization and surface reconstruction of 3D objects.

三物体的数化技及曲面重构技向工程的两个核心问题。

Hereinto, the numeralization of 3D prototype is the firstly important process.The accuracy of the objects’ numeralization will influence the quality of the digital reconstruction of the objects.

三的数化技向工程中的首要环节，其得到的数据精度将直接影响到重建模的质量。
