A new method of measurement under the condition of no intervisibility between control points

摘要

With the advancement of "smart cities", urbanization has developed rapidly and high-rise buildings have continued to increase. The intervisibility of measurement control points in surveying and mapping work is affected or even completely unable to pass through, which brings inconvenience to the quality and progress of surveying and mapping work. Based on the analysis of field scene, this paper designs a new measurement method under the condition which between the control points are not visible. At the same time, it is also difficult to calculate the target point coordinates by the space resection method. This measurement method also solves the problem that RTK technology is of poor signal quality and unstable accuracy in densely-constructed areas. By taking the urban construction intensive test area as the research object, we verify the measurement method, and the error of the test result meets the measurement accuracy requirement. It is suitable for use in total station surveying ,and is easy to operate and easy to use.
