在研究MOST移动目标空间模型的基础上,提出改进的移动目标空间模型(HCMOST),采用三次Herm ite插值方法模拟移动目标每个历史单元中的运动轨迹,并将运动函数中变化频繁的速度与不甚频繁的其余部分分离,并使多个对象可共享同一个运动函数公式,运动函数公式可以预先计算出来存放在共享列表中,从而使优化模型在精度和效率方面有了很大提高。从理论和实验两方面分析HCMOST模型的性能。 On the basis of studying the MOST moving target space model, an improved moving target space model (HCMOST) is proposed. The cubic Hermite interpolation method is used to simulate the moving locus in each historical unit of the moving target, and the fast changing speed Less frequently the rest of the separation, and make multiple objects can share the same motion function formula, motion function formula can be pre-calculated in the shared list, so that the optimization model has been greatly improved in accuracy and efficiency. Analyze the performance of HCMOST model from two aspects of theory and experiment.
