摘要
全站仪和反光镜轴线偏差对观测成果的影响不容忽视,通过分析全站仪轴线偏差对角度观测值和测距误差产生的原因和影响规律,给出了合理的改正措施,提高了测绘成果的精度,确保了工程施工质量和变形监测精度。
Axial deflection of total station and viewfinder has serious influence on observed value. Reasonable corrective measures are put forward through analysis on reason and law of the influence of axial deflection on observed angle value and observing distance, to improve the precision of plotting and to ensure engineering construction quality and deformation monitoring precision.
