A novel method of three-dimensional surveying with total station and RTK

针对传统RTK高程测量存在精度低的问题,提出一种全站仪与RTK协同作业三维勘测新方法。设计一种附有反射护圈和嵌置小棱镜的RTK接收机天线改造方案,给出全站仪与RTK协同三维测量的几何关系,并从自由设站三角高程测量模型和四参数转换模型两个角度设计全站仪与RTK协同作业三维勘测模型。实验结果表明,利用本文方法测量获得点位的平面坐标与传统的RTK测量结果是一致的,但高程测量结果准确度提升了0.011m,本文方法是行之有效的,可为工程勘测设计应用提供一种三维测量作业新模式。

Aiming at the problem of low-accuracy in traditional RTK leveling surveying,a novel method of three-dimensional surveying of total station and RTK collaborative work is proposed.A reconstruction scheme of RTK receiver antenna with reflecting-arc and embedded small-prism is designed.The geometric relationship between total station and RTK collaborative three-dimensional surveying is given,and the three-dimensional surveying model of total station and RTK collaborative work is designed from the perspective of free station trigonometric leveling surveying model and four parameters conversion model.The experimental results show that the horizontal coordinates of the points obtained by the proposed method are consistent with the traditional RTK surveying results,but the accuracy of the leveling surveying results is improved by 0.011m.This method is effective and provides a new mode of three-dimensional surveying for the application of engineering surveying and design.
