摘要
利用巴尔达传统粗差检验方法检验剔除出数据中的粗差,并通过稳健估计方法处理含有粗差的数据以及传统平差方法处理剔除过粗差的数据,与加入粗差前的数据处理结果作对比,比较不同粗差处理方法的优缺点。经比较得出:在保证一定迭代计算次数的条件下,稳健估计能够达到抵抗粗差的目的;巴尔达粗差探测在数据中只含有一个粗差的情况下,与稳健估计相比,在满足一定精度要求的前提下,更能保证计算效率;在数据含有多个粗差的情况下,可利用稳健估计方法进行处理。
Baarda's traditional gross error test method was used to test and eliminate the gross errors in the data.The data with gross errors were processed by robust estimation method and traditional adjustment method respectively,and the results were compared with those before adding gross errors.The advantages and disadvantages of different gross error processing methods were compared.It is concluded that under the condition of ensuring a certain number of iterative calculations,robust estimation can achieve the purpose of resisting gross errors.Compared with robust estimation,Baarda gross error detection can ensure the calculation efficiency on the premise of meeting certain accuracy requirements when there is only one gross error in the data.When the data contains multiple gross errors,the robust estimation method can be used for processing.
