摘要
地形可视计算在军事侦察、土地管理以及建筑学等领域都有重要的研究意义。地形可视计算领域的LOS(line ofsight)算法有在空间上计算不平衡的问题。提出了一种分层地形可视计算的改进方法。该方法通过对地形区域进行分层,使地形可视计算在空间上相对平衡。与增量法进行比较,运算效率有了较大的提升。
The computation unbalance of the LOS (line of sight) algorithm in visibility computation field is analysed, A level based approach is presented, which improves the original LOS algorithm. The terrain is divided into several parts. The visibility computation relatively balance in space is maken. Compared with incremental terrain visibility computation, the approach is faster.
