Abstract

In the precision engineering measurement, the total station is often used for free station measurement, and improving the accuracy of stitching the measurement data of each station is the premise of widely used total station measurement by free setting. This paper is based on the quadratic method to study the stitching method of data measured by total station with free set-up stations. The total station data is obtained by free setting based on the quaternion method, and the method of stitching the data is investigated. Taking the deformation monitoring of the wooden tower in Yingxian County as a case study, a total station was measured by free setting, and the quadratic algorithm was used to realize the coordinate conversion between stations by point name matching, which is comparable to the stitching results of Leica's Cyclone software. In this paper, the improved quaternion algorithm is applied to the free station splicing of total station with the features of fast matching, coarse difference detection and rejection, optimization of redundant observation of the same name point splicing algorithm, inclusion of splicing error correction, and high splicing accuracy.
