Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as figure 1 As shown in FIG. 1 , it is a schematic flow chart of the free station setting method based on single-disk position measurement in the present invention. A method for freely setting up stations based on single-disk position measurement, comprising the following steps:

[0027] A. Select the total station for station setup, and preprocess the total station;

[0028] B. Use the total station to aim at and measure two backsight points, obtain the approximate coordinates of the site, and use the single-disk measurement method to obtain the observation data of the remaining back...

Abstract

The invention discloses a free station setting method based on single disk position measurement. The free station setting method includes the steps that a total station is selected for pretreatment, observation data of rearview points is obtained, a three-dimensional adjustment model based on vertical disk index difference parameters is constructed, a station setting coordinate and a vertical diskindex difference are calculated, and free station setting is carried out. According to the free station setting method based on single disk position measurement, the vertical disk index difference istaken as an additional parameter, the station setting coordinate and the vertical disk index difference are calculated by adjustment through the observation data of multiple groups of the rearview points, the point position accuracy of a station setting point is effectively improved, and the necessary requirements of free station setting to the total station is lowered.

Description

technical field [0001] The invention belongs to the technical field of engineering surveying and mapping, and in particular relates to a free station setting method based on single disk position measurement. Background technique [0002] At present, the free station setting of the total station usually uses the instrument's own program to set up the station. The total station calculates the coordinate point of setting up the station through more than 2 known points. "High-Speed ​​Railway Engineering Measurement Specifications" (TB10601-2009) stipulates that when the error in the point position exceeds the limit during free station setting, it is necessary to manually remove the exceeding limit points, and then recalculate until all indicators meet the specifications. However, the self-contained program of the instrument now uses the half-disc position to set up the station freely. When the instrument has a vertical disc index difference, the calculated elevation of the stat...
