| 摘 要： | 为了能够更加深入地了解人体运动和动作技术的细节,为使分析结果更接近实际情况,提高测量数据的准确性,通过对三维摄像中超出标定范围的被标定点进行标定的方法,分析其标定精度,确定误差范围。得到的结论是,针对目前国内研究人员常用的25个控制点的辐射型标定框架,标定范围应控制在距标定框架中心起4.5m的空间范围内,以保证测量数据的准确性。

| Abstract: | In order to have an in-depth understanding of the technical details of human motions and to make the analytical results more authentic to improve the accuracy of research data,the authors have analyzed the calibration accuracy and determined the error range by calibrating the control points that exceed the control space in three-dimensional photographic measuring method.The conclusion is that the control space should be within the radius of the targeted frame of not more than 4.5 meters corresponding to the Frame of 25 control points used normally by the domestic researchers so as to ensure the accuracy of research data. |
