摘要
为测试球形嵌入式空心角锥反射镜(SMR)配合全站仪的测量性能,本文从棱镜基本结构和棱镜常数出发,分析了SMR棱镜的入射角范围及其对观测结果的影响,基于高精度旋转平台,以SMR棱镜为合作目标,对全站仪近距离动态测量精度进行了检测,结果表明,入射角变化对测量结果的影响与距离有关,在低动态条件下,SMR棱镜配合TCA2003的近距离动态测量误差优于3mm。
To test the measurement performance of total station cooperated with SMR prism,the structure and prism constant of SMR were introduced,range of the angle of incidence and its effects on results of observation were analyzed.Based on the dynamic platform and SMR prism,precision of dynamic surveying for total station was tested in close quarters.The conclusion indicated that effects of the angle of incidence on measurement were correlated with measurement distance,the precision of dynamic surveying for TCA2003 was within 3mm in close quarters and low dynamic conditions.
