摘要
由于在三维空间中如何来判定空间任意体之间的空间关系是相当困难的,因此空间最优视界覆盖问题是一个值得研究的方向。针对空间分析中最优视界覆盖问题进行了研究。首先建立了点源的各向同性非约束视界覆盖模型,然后引入具体的地形约束,利用模糊综合决策模型构造代价函数,从而确定了三维空间上点源模型的有约束最优覆盖。最后通过实例验证了该方法的有效性。
It＇s difficult to estimate the spatial relationship of the random spatial object in three-dimensional space, so optimal horizon overcastting in spatial analysis is a valued branch to be studied. A study on this question is discussed. At first, an isotropy horizon overcastting model without restriction for point source is set up. After the terrain restriction is introduced, a cost function with the fuzzy synthetic decision model is formed. Then, the optimal overcastting model of three-dimensional space with restriction is confirmed. At last, a test is made to validate the availability of the method.
