城市可视性在城市作战中具有重要的作用,可视性情况是指挥员必须要考虑的作战要素之一.首先从城市作战行动、武器装备运用和作战人员三个方面探讨了可视性对城市作战的影响,研究了基于城市RSG高程数据的LOS可视算法、平面视域算法,并扩展到立体视域计算,利用三维视球法建立了城市可视性衡量的指标模型,提出城市作战可视性专题图的设计思路,分别以观察哨、城市可视性分布为例,制作了专题图实例.%Urban visibility plays an importance role in urban warfare.In MOUT,commanders need taking the urban visi-bility situation into consideration.In this paper,it analyzes the influences of the urban visibility from aspects of military operation, weapon equipment and war-participators. Based on the usual methods, it studies the LOS visualization algo-rithm based on RSG elevation data and extended to stereoscopic field calculation.The visual model of urban visualization is established by using three-dimensional sphere-of-view method,the design ideas of city operational visualization thematic map are put forward,and it makes examples of observation map,city visibility map.
