人体重心动摇轨迹的包络面积算法

在林业生产过程中，诸如跌倒、坠落等事故的发生都与人体平衡功能有着密切的联系.因此平衡功能的研究对于保障林业作业安全意义重大，BSR1型人体平衡功能测试仪也为此目的而研发.为了进一步提高该测试仪对人体平衡功能测试指标之一的人体重心动摇轨迹包络面积的测量精度，该文研究了此测试仪对人体重心动摇轨迹的记录方式及其所得轨迹包络曲线的特点，并对一系列算法进行了比较分析，提出了适于该测试仪包络面积测量的合理算法，并将其编写到BSR1型人体平衡功能测试仪的软件程序中.经过验证，新算法可准确地测量出人体重心动摇轨迹包络面积. 

Algorithm of envelope size of the body barycenter swaying trajectory

In the forestry production, the accidents, caused by the case of body unbalanced like tumbling and falling, have a tight relationship with equilibrium function. Therefore, study on equilibrium function is very important to ensure the safety of forestry production, and the BSR-1 Body Balance Testing Instrument was worked out on this purpose. In order to improve the testing precision of the envelope size of body barycenter swaying trajectory, one of the indices of the instrument, the recording mode and characteristics of the instrument were studied in this paper. An optimal algorithm to the instrument was put forward based on the study of several algorithms. The new software of the BSR-1 Body Balance Testing Instrument was compiled. It has been proved that the new software can calculate the envelope size of human body barycenter swaying trajectory accurately.
