摘要
利用全站仪在野外进行测量时,往往会出现两个所给控制点不通视的情况。此时利用常规的交会方法将无法进行下一步工作。在对全站仪自由设站的原理和方法进行分析后,全站仪自由设站方法可以快速的解决上述问题。且自由设站方法精度高,设站灵活,不受后方交会危险圆的限制。
Surveying in the field with total station, sometimes there is trouble： the orientation can not be finished because some barriers appear between the total station and prism. It will prevent the next work, and the problem can not be solved by common intersection methods. Based on the analysis of the theory of free-station method, this paper introduces the free-station method to figure out the problem readily. In addition, the result of free station is precise, the placement of instrument is flexible, and this method of total station can avoid the dangerous circle of resection.
