| 摘 要： | 测距仪检定时乘常数是用频率测量方法取得,加常数及测距标准差是用短基线测定,由于仪器检测例的条件与工程现场条件不一致,检测的标称精度不能真实反映实际观测精度,以标称精度定权处理观测数据,影响测量成果的质量;指出综合运用测量平差与回归分析,可对工程中使用的测距仪实际观测精度进行有效评估为仪器性能判别及测量数据处理准确定权提...

| Abstract: | The nominal accuracy of electronic distance-measuring instrument(EDM) is determined by the calibration during which multiplying constant is obtained by measuring its frequency and additive constant comes from the base-line field which is not fit the real project because of the different conditions between them,so it will cause some deficiencies in the observation-data process.A combined method that includes surveying adjustment and regression analysis was given to estimate the real accuracy of the EDM in th... |
