摘　　要：大视场光学经纬仪是重要的靶场测试设备,通常采用依托平行光管真值的分区建模误差修正方法对大视场光学经纬仪的全视场测角误差进行校正。为了进一步提高大视场红外经纬仪全视场测角精度,提出依托经纬仪完全对准平行光管时的指向值作为光学标校的基准值的分区误差修正处理方法,分别采用依托真值和指向值2种不同的修正方法构建2种修正模型,并解算同一被测目标的空间角度,进行对比实验,结果表明,依托指向值的分区误差修正方法能够获得更好的测角精度。The large field optical theodolite is an important test equipment for the shooting range.Usually,the full-field angle measurement error of the large-field optical theodolite is corrected by using the partition modeling error correction method based on the true value of the light pipe.In order to improve the full-field angle measurement accuracy of large-field infrared theodolites,this paper proposes a divisional error correction method that relies on the theodolite's pointing value as the reference value for optical calibration.Two different correction methods based on the true value and the pointing value are used to construct two correction models respectively,solve the spatial angle of the same measured target,and carry out comparative experiments.The results show that the divisional error correction method based on the pointing value can obtain better angle measurement accuracy.
