摘　　要：随着运动捕捉对嵌入式系统要求的提高,传统方法对分辨率、采集速度难以兼顾,硬件规格高,迫切需要得到改进。新方法把运动物捕捉分成对分辨率和速度侧重不同的运动检测和目标提取两个部分,利用有源象素结构APS-CMOS图像传感器可随机接入图像缓存的硬件特性在DSP平台上实现两个阶段特点各异的工作模式切换。这样就使得整个系统的采集速度和目标分辨率同时得到保障。因此,此方法使用一般器件就可实现传统方法中高规格器件才能达到的技术指标。With the growing requirement of motion capture in embedded system,it is hard to balance the conflict between resolution and capture speed, and the system needs high performance chips in traditional ways.This new method splits motion capture process into motion detection and target capture these two parts of different emphases on resolution or speed.Using active-pixel architecture,CMOS image sensor's hardware characteristics can random access the sensor's image buffer,to achieve the switch about work mode of varying trait on DSP platform.Thus,the whole system's capture speed and resolution both can be guaranteed.Therefore,with this method,ordinary chips can achieve higher technology index which can only be traditionally done with higher performance chips.
