为了将抽象的测试数据变成直观的运动,并为进一步改进弹丸性能提供可靠的依据,文中研究了基于虚拟现实的弹丸时空位置再现技术,详细介绍了弹丸姿态和位置确定的方法,基于VRML弹丸模型的构建,以及模型的驱动,利用一组测试数据进行了仿真,仿真结果的正确性被高速摄影所证实,表明基于虚拟现实的弹丸时空位置再现技术是一种可行的弹丸运动仿真方法,具有很好的推广价值。

The reappearance technology of position and time for projectile based on the virtual reality was studied for making the abstract test data to direct viewing movement and providing the reliable basis to improve the projectile performance further. In the paper, the attitude and position determination method of projectile is introduced in detail, the construction and actuation of projectile model based on the VRML also is introduced, and the simulation was carried on using a group of test data, the correctness of the simulation was confirmed by the image from high-speed photography. It is indicated that the reappearance technology of position and time for projectile based on the virtual reality is one of feasible movement simulation methods of projectile, and has good promoted value.
