摘要
针对高精度水平基准装置人工调试时人为误差大,费时费力等情况,对水平基准装置进行了自动化升级改造,并采用A类与B类标准不确定度的组合评分方式对升级改造后的图像测量系统进行不确定度分析,经检验其能满足计量检定的精度要求。
A high-accuracy horizontal reference device is very important for verification of instrument of surveying and metering. At present the debugging of high-accuracy horizontal reference device is men-made, which wastes much time and with large error, therefore, it is necessary to make this equipment automation retrofits. The uncertain- ty analysis image measurement system after upgrading was studied by the combination of evaluation methods using standard of class A and class B, the results show that the transformation accuracy can meet the requirements of metrological verification.
