| 摘 要： | 对影像测量过程中的人工解析误差进行了实验研究,对关节点位移参数和角度参数的解析结果表明,上述参数的相对误差和误差波动范围较小。位移、角度及速度参数的解析精度高于加速度和角速度参数。多次解析得到的加速度和角速度参数在整体的变化趋势上保持一致,但误差波动范围较大。

| Abstract: | The text has performed the experimental study of manual resolution errors during vidio measurment.The result of quantization about joint point displacement and angle shows that the relative errors is small and the wave range of errors is also in the low level.The precision of parameters of displacement,angle and velocity are higher than the parameters of angle speed and acceleration.The trends of the result of repeatedly quantization about the angle speed and acceleration is consistent on the hole,but the wave range of errors is more big. |
