红外测距仪参数的监测与亏秩平差

The Way of Rark-Defect Freenetwork Adjustment for the Monitoring of EDM Parameters

  • 摘要: 本文讨论用秩亏自由网平差方法监测红外测距仪参数的漂移。首先证明以全组合法检测仪器参数的平差问题属亏秩平差范畴,然后讨论两种平差方法及相应的漂移显著性检验,并以算例说明具体实施步骤。结论是:只要充分注意监测精度,可以起到监测参数漂移的作用,从而减少例行的去专用基线场检测的各种耗费。

     

    Abstract: This paper discusses the drifts of monitoring EDM parameters by the way of rank-defect freenetwork adjustment.In the first place,it is proved that the adjustment of monitoring EDM parameters with the combinatorial method is a problem of rank-defect adjustment.After that,two ways of adjustment are discussed,the tests of significant drifts of parameters are studied and several examples are given.The conclusion is drawn that these methods will be effective in monitoring EDM parameter drifts and reducing the test costs to baseline site for the special purpose if we pay sufficient attention to advancing the monitoring accuracy.
