一种三维目标几何参数测量技术

Parameter Calculating Technique for Three-Dimensional Objects

在分析离散数据表示的三维物体体积和表面积计算方法的基础上，本文提出一种新的通过断层图象序列计算三维目标体积和表面积的方法．该方法通过断层间插值运算，使各断层间目标形状均匀变化，目标的三维表面更加接近真实情况，提高了计算精度．该方法已在微机图象处理系统上实现．文中给出了计算人体肝脏体积和表面积的实例．

The volume and surface area calculating methods are analysed and then a new calculating method is presented in this paper. By using interpolation method, the shape of a 3-dimensional object in each interpolational cross-sections changes gradually. This is close to the reality. The calculating results are more accurate. As examples, the calculating results of volume and surface area of human liver are given.
