摘　　要：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 visibility 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 algorithm 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.
