联合RTK和支距法测定建筑物角点的方法及应用

Method and Application of Combined RTK and Offset for Measuring Building Corner

针对实时动态（real-time kinematic,RTK）技术无法测定建筑物角点的问题,提出一种基于支距法的建筑物角点测量方法。该方法可以有效解决RTK接收机易受建筑物的遮挡、RTK接收机天线自身的几何形状易对测定结果产生偏差等问题。通过实测数据进行精度分析,表明该方法实用、有效,并在郑州市宅基地地籍测量项目进行推广应用。

Aiming at the problem that building corner can not be measured by RTK technique,this paper proposes a corner measurement method based on offset method.The method can effectively solve the problems that the antenna of the RTK receiver is easily sheltered by the building and the geometry of the antenna of the RTK receiver is easy to deviate from the determination result.The accuracy analysis of the measured data shows that the method is practical and effective,and is applied in the cadastral surveying project of residential sites in Zhengzhou.
