摘要
利用现代测量仪器和技术可以在短时间内获得大量的观测数据,但其中也包含着大量无法补偿的系统误差,因此参数的估计量会产生严重偏差。本文从半参数模型的理论研究成果和测绘科学的实际需要出发,研究半参数模型的估计方法测绘数据处理中的应用。
We can attain lots of observation data in shorter time with the modern surveying equipment and technology. But these data contains the plenty of uncompensated systematic error,and the parameter estimation will cause a serious bias estimator. This paper combines the theoretical research results of semi-parametric model and the actual needs of surveying science,focuses on the estimation methods of semi-parametric model and the application on the surveying data processing.
