| 摘 要： | 通过改变2台摄像机的拍摄夹角对三维视讯运动图像进行拍摄,获得三维坐标标定精度误差,并运用数理统计法对所得误差进行统计学分析,结果表明:各拍摄角度具有不同的适用范围,故在实际操作中需根据不同技术动作选择适当的三维拍摄角度,从而确保最小的误差范围.

| Abstract: | Three-dimensional framework of shi-xun motion image analysis system has been shooted by changing the angles between two cameras in order to obtain precision error.Mathematical statistics methods has been used for analyz the income error which showed that different shooting angles accord to different scope of applicability.So,in practical operation,it is very important to select proper three-dimensional shooting angle for different technical action so as to insure the smallest error range. |

| Keywords: | three-dimensional framework shooting angle image analysis precision |
