为满足人体关节运动模型研究的需要,设计了一种基于机器视觉的肢体运动模式采集系统,系统由PC I-1411视频采集卡和LabVIEW数字图像处理平台构成。通过对采集到的肢体运动状态视频分帧进行处理,建立了肢体关节运动的相关数学模型,获得了较为准确的肢体运动参数。研究结果表明,采用视频采集技术建立的运动模型较传感器采集技术建立的模型有精确度高、处理速度快、系统误差小、数据易分析处理等优势。

In order to study the human motion model,a limbs movement pattern acquisition system is designed which consists of PCI-1411 video capture card and the digital image processing platform based on LabVIEW machine vision.This research sets up the mathematical model motion of relevant limbs through processed video frames of the limbs movement,and obtains the accurate parameters of limbs movement.The results show that the movement model established by the video capture technology has the advantages of higher accuracy,faster processing speed,less system error,and easy analyzing and processing function over the models based on sensors acquisition technology.
