摘要
针对光电自准直经纬仪的水平角测量原理和系统组成特点,全面分析了影响其水平角测量精度的各项误差分量,并对各种误差因素进行了定量计算,对系统误差提出补偿方法。通过分析和补偿,可将光电准直经纬仪水平角测量精度提高到0.5″,满足Ⅰ等电子经纬仪的测量精度指标。
Aiming at the horizontal angle measuring principle and system composition of photoelectric autocollimatic theodolite,the measuring error components,which effect measurement accuracy of the horizontal angle,are analyzed comprehensively and calculated quantitatively.The compensation methods are put forward for system errors.By anylyzing and compensating these errors,the measurement accuracy of the photoelectric autocollimatic theodolite horizontal angle is improved to 0.5",which meet the accuracy requirements of level I electronic theodolite.
