基于钻孔数据重构地层周围表面模型算法

An Algorithm of Reconstruct Strata Surface Based on Borehole Data

论文根据地层钻孔数据的特点,提出了采用最近邻优先法与Delaunay法相结合的重构地质体周围表面模型算法,能对任意形状的轮廓线(连续环形的和不连续间断的、凸形和凹形)进行统一建模,形成局部最优的三角形网格。该算法既可适用基于钻孔数据的地质体周围表面模型重构,也可用于地学、医学、矿业、石油行业基于切片级图像重建,有着广泛的应用前景。

Considering the specialty of strata drilling profile,a new algorithm of reconstructing strata surface has been developed.The method can not only effectively reconstruct surface mesh with optimized triangle based on the circularity contour lines but also can generic triangle surface which be locally optimized with arbitrary shape such as discontinuity face,protruding face and convex face.The method can be used in geology,medical,mining,rock oil etc.to rebuild object surface.
