摘要
提出了一种高效的海量空间目标可视化方法。首先,根据空间目标轨道根数的6维数据,采用分段方法,实时动态计算空间目标轨道采样点;然后,根据当前时刻插值计算目标当前的位置;最后,采用空间裁剪算法,裁剪当前视角下被地球遮挡的空间目标,并通过调用图形绘制接口,编程实现空间目标的可视化效果输出。试验结果表明,该方法可有效对海量空间目标进行可视化输出。
An effective method for massive space target visualization is proposed.Firstly,according to the 6-D orbital elements of the space targets,the sectional method is used to dynamically calculate the sampling points of space target orbits in real time.Then,the present position of space target is calculated via interpolation by the current time.Finally,with the space-clipping algorithm,the space targets sheltered by the earth in current view are clipped.By calling the graphic drawing interface,the rendering results of the space targets are output.Experimental results show that the method can be effectively applied in massive space target visualization.
