摘　　要：三维实体重构是工程规划和设计以及管理等各项技术的基础。采用AutoLISP编程方法,基于距离反比加权法和Delaunay三角网法插值原理,开发出了一套工程数据处理程序。该程序能进行离散点数据插值、三维数字地面模型的生成、三维实体重构和工程土方量计算。采用这一方法编制的程序具有移值性强、操作方便直观、适用范围广、计算精度高等特点。同时,该程序能大大减轻工程人员的工作强度,提高工作效率。该程序的使用不仅有利于设计人员对工程计算结果的判断和利用,而且有利于设计人员对设计作出及时地调整,从而达到优化工程设计、减少工程费用的目的。Three-dimensional solid reconstruction is the technological Dasls oI engmeelm~, ptaimm~,, ~ o- ment. By using AutoLISP programming method and employing the interpolation theories with inverse distance weighted method and Delaunay triangulation method, a program is developed for engineering data processing. This program can carry out a dis- crete point data interpolation, three-dimensional digital terrain model generation, three-dimensional solid reconstruction and en- gineering earthwork calculation. With the proposed method, the program has strong interoperability, easy and visual operabili- ty, wide applicability, and high accuracy. At the same time, the program can greatly reduce the working strength of engineers and improve the work efficiency. And furthermore, the application of this program is not only beneficial to the designers to es- timate and utilize the results in engineering calculations, and is helpful for designers to make a timely design adjustment, so as to optimize the engineering design and reduce the proiect costs.
