摘　　要：推算定位技术是大型分布式实时视景仿真系统中减少网络传输数据量的关键技术。在战术推演过程中,为了在减少数据交互的同时使舰船造型的运动变得连续、平滑,针对舰船运动状态变化缓慢的特点,分析了舰船的几种典型的运动模式,提出了基于运动模式的DR算法。在三维可视化端进行了实体运动状态的细化,并采取延时差异补偿方法保证了三维显示的平稳性和逻辑性。仿真结果证明了该算法的合理性。Dead reckoning algorithm which can reduce the network-data stream in the large-scale distributed real-time visual simulation system is a key technology.In order to reduce the data interacting,as well as keeping continuity and smoothness of movement for the warship model in the wargaming process,making use of the characteristic that the movement state of warship changes slowly,several representative movement modes of the warship have been analyzed and a movement mode based dead reckoning algorithm has been proposed.At the three-dimension visual port,the movement model of the warship entity has been described in detail and the delay-time difference compensation method has been adopted,realizing the smoothness and logicality of the visual movement of the warship.Experiment verifies the rightness of the improved algorithm.
