摘要(Abstract)：
传统的人体下肢动作捕捉系统能够对人体进行快速的动作捕捉,但是由于动作幅度较大不能在大范围的运动过程中对下肢关节进行动作捕捉。针对上述问题,设计了一种大范围运动过程中人体下肢动作捕捉系统。在硬件处理上采用新型的BOT-6765连续动作捕捉系统,使用待换机的层次运行结构改变传统的捕捉选定的结构过程,提升了动作捕捉过程的测量范围,同时减小了捕捉过程中背景虚设的帧,有效地提高了人体下肢动作捕捉过程的清晰度。软件上建立了简化模型,保证捕捉过程中的准确性,同时能够提高捕捉范围,优化了人体关节角的运算,人体下肢关节是捕捉过程的关键所在,优化后的关节运算存储量小、捕捉准确,避免计算误差的产生。为了验证设计的大范围运动过程中人体下肢动作捕捉系统的有效性,设计了对比仿真实验,通过实验数据的分析,有效地验证了设计的大范围运动过程中人体下肢动作捕捉系统的有效性。
