摘　　要：目的研制一套适用于人体站姿、坐姿平衡功能测量的便携式人体平衡功能测量系统。方法人体姿态发生变化后,运用光电技术和图像处理技术将固定在被试者头部中央视标移动轨迹转化为人体重心移动轨迹,通过对该轨迹的分析,定量测量出人体平衡功能。结果和结论设计出该系统。利用该系统对一志愿者饮酒前后的平衡功能进行测量比较,表明测量结果可靠。ObjectiveTo develop a portable body balance testing system for posture of standing and sitting.MethodsAs the body sways, balance indicator fixed on the centre of head will change with the swaying. The tract of the swaying indicator will be translated to tract of the posture by the means of photo-electricity and image processing. The body balance function will be measured quantificationally after the tract is analysed.Results and ConclusionThe system has been developed. With the aid of this instrument, the body balance function of one volunteer pre-drinking and post-drinking has been measured and compared. [
