The principle of system design is as follows: At first, compartmentalizing the arithmetic of sterovision measurement. We use FPGA logic units Customized hardware blocks to implement the arithmetic which is simple and large data-computing, and the data is transferred on pipeline between each blocks, otherwise, use software program in NiosⅡ to implement the complicated and small data-computing arithmetic. So the system is high-speed and flexible.

系统设计的基本思想如下：首先针对视觉测量算法进行划分，对算法简单、数据处理量大的部分用 FPGA逻辑单元自定义硬件模块的方法实现，各硬件模块之间数据采取流水线操作；算法复杂、数据处理量小的部分则在 Nios II软核中用软件的方法实现，从而使本系统既具速度优势又具良好的灵活性。

Cutting process of soft tissue and organs is very important in virtual surgery simulation. Tetrahedron is widely used to construct the geometric model of virtual organs. Efficient methods must be developed to split or merge tetrahedrons in order to adapt to topology changes during cutting process. The main parts of this thesis are the two chapters on "Reconstruction of Tetrahedrons" and "Stability of Tetrahedrons".Main research work I have done is listed as follows:1 Reconstruction of Tetrahedrons.

人体软组织及器官的切割仿真是虚拟手术仿真的重要组成部分，软组织及器官的几何模型普遍采用四面体模型，切割的同时，软组织及器官的拓扑结构发生变化，模型中的部分四面体基元必须能够通过分裂或合并以适应上述变化，医学数据在三维场景中的交互和可视化是手术仿真的基本要求，因此，第二章&四面体重构&以及第三章&四面体单元稳定性&是本文重点讨论的两个部分。
