摘要
半参数模型增强了模型的适应性,在测绘数据处理中得到越来越广泛的应用。采用半参数模型对传统的布尔莎七参数模型进行改进,利用公共点坐标数据进行分析计算,并讨论半参数模型中正则矩阵的选取对模型精度的影响。为传统大地坐标转换提供一种解决途径。
With the incremental of model adaptability , semiparametric model is widely used in processing mad data .By the help of improvement to traditional Bursa seven -parameter model , analyzing and calculating common point coordinate data and discussion a -bout the influence of the selection of Regular rectangular to model accuracy , there is a solution to traditional geodetic coordinate sy-sytem.
