中文摘要：

提出了一种对复杂图形进行三维重建的新方法：将复杂图形分割成若干个同质的简单子图形，对各子图形分别进行三维重建后进行拼接，以实现复杂图形的三维重建，井以相图的三维重建为例说明了此方法的必要性、可行性及实现。

英文摘要：

To study a new 3D reconstruction method of complex graph： the complex graph is divided into some sub-graphs, which are 3D-reconstructed individually and then mosaicked. The necessity, feasibility and implement of this method is described by 3D reconstructing of phase diagram.
