摘要
针对Bursa七参数模型在参心坐标系与地心坐标系转换后仍存在较大残差的问题,通过对坐标转换模型误差进行分析,提出将模型误差看作非参数信号的半参数估计的补偿最小二乘模型进行处理,并利用实测数据进行分析计算,试验结果表明:该方法能够有效地消除模型误差等残差,实现高精度的坐标转换。
There is still a big residual in coordinate conversion between reference and geocentric. By analy zing the model errors, it presents a penalized least squares model that regards the model error as a semi non-parametric signal. Through calculating and analyzing the measured data, this model can effectively e liminate the residual model error, to achieve high-precision coordinate transformation.
