基于激光跟踪技术的运动姿态拟合研究

Research on motion attitude fitting based on laser tracking technology

针对传统拟合方法在拟合运动姿态数据点时,拟合数据点过少的问题。提出了一种基于激光跟踪技术的运动姿态拟合方法。首先使用激光跟踪技术获取运动姿态坐标数据点,利用径向畸变处理激光照射反馈回来的激光信号,换算计算出运动姿态坐标数据点,然后曲线拟合运动姿态数据点,首先规定坐标数据点的窗口相似度,使用雅克比矩阵计算姿态数据点,得到数据点的离散点,使用曲线拟合公式拟合姿态数据的所有数据点,完成对运动姿态的拟合。实验结果表明:与传统运动姿态拟合方法相比,基于激光跟踪技术的运动姿态拟合方法,可以拟合更多的运动姿态数据点,是一种更优秀的拟合方法。

In order to solve the problem that there are few fitting data points in traditional fitting method.A method of motion attitude fitting based on laser tracking technology is proposed.Firstly,the laser tracking technology is used to obtain data points of motion attitude coordinates,and the radial distortion is used to process the laser signals fed back by laser irradiation,and then the data points of motion attitude coordinates are converted and calculated.Secondly,the curve is used to fit the data points of motion attitude.The window similarity of coordinate data points is specified firstly,and the attitude data points are calculated by using Jacobian matrix,and the discrete points of data points are obtained.The curve fitting formula is used to fit all data points of attitude data and complete the fitting of motion attitude.The experimental results show that compared with traditional method,the method based on laser tracking technology can fit more data points of motion attitude,which is a better fitting method.
