本文总结了徕卡TCR1200系列免棱镜全站仪的作业应用方法,对于推广免棱镜全站仪的应用具有参考价值。从2005年以来,免棱镜全站仪逐步在各类测量中应用,如在控制测量、地形测量、变形工程测量、地籍测量和地下隧道工程测量中应用。实践证明免棱镜全站仪具有节约人力、提高效率、使外业工作量及测量成本大大减少等优势。 This article summarizes the application of the Leica TCR1200 series prism-free total station instrument, which is of reference value for the promotion of the application of prismless total station. Since 2005, Prism-free Total Station has been gradually applied in all kinds of surveying, such as control survey, topographic survey, deformation engineering survey, cadastral survey and underground tunnel engineering survey. Practice has proved that prism-free total station saves manpower, improve efficiency, so that the field of work and measurement costs greatly reduced and other advantages.
