摘　　要：设计和实现了一个用于辅助蹦床运动科学训练的计算机模拟与仿真软件系统VHTrampoline.其原理是:在人体运动生物力学数据和真实人体运动捕获数据的基础上,通过运动编辑技术实现技术动作的修改和成套技术动作的模拟,并用人体运动方程分析和验证模拟结果;同时,基于虚拟现实方法将模拟结果与真实视频同步对比实现可视化的分析.除了必须的交互操作,文中涉及到的计算都是实时的.与传统训练方法相比,该系统具有直观、量化等优点.The three dimensional trampoline simulating system, VHTrampoline, for computeraided athlete training is designed and implemented in this paper. Deriving from human motion biomechanics data and motion capture data of real performance, both design of the trampoline Sport and simulation of the routine one are implemented based on motion editing techniques. Further, the simulated motion is verified and analyzed with dynamic human motion equations. Meanwhile, the visual analysis can be reached through comparing the videotaped motion with the simulated one synchronously. Besides the necessary interaction operations, all of the computations are almost real time. The motion training method and system presented in this paper are more of visual and quantitative compared with the conventional ones.
