摘 要: 利用C#语言在AutoCAD二次开发环境下,实现了读取、显示盐穴测量数据,并在同一投影平面上求出各个水平剖面的并集,即盐穴的最大占地面积。深入分析盐穴测量数据文件的记录格式,忽略数据的深度值,读取数据并显示在同一水平面上。利用凸壳算法,寻找该水平面上点集的最外围凸边界,并根据需要,判定是否对该区域进行填充。计算出盐穴在水平投影面的最大投影范围,提高了盐穴的安全性,避免了盐穴因超出最大安全距离而形成塌陷。
关 键 词: 大地测量学;摄影测量学与遥感测量;盐穴储库;AutoCAD;凸壳算法

Abstract: In this paper, this kind of data is served as initial data and combined with programming language C# and AutoCAD platform, the algorithm of convex hell is realized to display the data and then commutate the maximum outline of horizontal section of salt cavern, and the result is proved feasible. Given in detail, firstly, the data structure of dat file is analyzed, then the deeper information is omitted to draw all the points in the same horizontal plane, then the convex hull algorithm is adopted to compute the points on the periphery in the data set. Finally the maximum horizontal outline is formed by connecting all those finding points together.
Key words: geodesy; photogrammetry and remote sensing; salt cavern storage; AutoCAD; convex hull algorithm
