摘　　要：人体姿态发生变化,其身体的重心也将发生相应改变,固定在被试者头部中央的视标也发生相应变化。本系统运用光电技术和图像处理技术将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。采用这一原理,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。利用该系统对15个志愿者饮酒前后作平衡功能测试,发现饮酒能严重影响人的平衡功能。As the posture sways, body balance chaged with the swaying indicator ,fixed on the centre of head. The tract of the swaying indicator would be translated to tract of the posture by the means of photo-electricity and image processing. The body balance function would be measured quantificationally after the tract was analysed. Based on the above principle, the portable body balance testing system for posture of standing and sitting was developed. With the aid of this instrument, the body balance function of 15 volunteers were measured pre-drinking and pos-drinking That alcohol took bad effect on the body balance function was found.
