[0047] Since the problem is derived from a practical problem, there must exist a solution to the equation. Solve this system of equations analytically or numerically, passing t...

Embodiment 3

[0049] Total station free leveling measurement method: as attached image 3 as shown, XYZ is the internal coordinate system of the total station, X'Y'Z' It is the earth coordinate system, to realize the transformation of the two coordinate systems, first translate XYZ origin of the coordinate system O , make it with X'Y'Z' The coordinate origin O' coincides (as attached Figure 4 ), get the coordinate translation [ ΔX ΔY ΔZ ] T ;

[0050] The three-dimensional coordinate transformation model according to formula (2)

[0051]

[0052] The scale ratio between the internal coordinate system of the total station and the earth coordinate system mu Equal to 1, coordinate translation [ ΔX ΔY ΔZ ] T is the site coordinates of the total station P ( x 0 , y 0 , z 0 ), which can be obtained by the formula (1) of the total station without setting up the station freely.

[0053] That is, formula (2) can be transformed into:

Abstract

The invention discloses a non-horizontalization free established station for a total station and a project measurement method of the non-horizontalization free established station. The invention belongs to the technical field of project measurement. The non-horizontalization free established station for the total station and the project measurement method are characterized in that (1) the total station is in a non-horizontal working gesture; the total station is operated to measure a slope distance, a horizontal angle and a zenith distance of at least thee geodetic datums; (2), according to the obtained measurement information of geodetic datums, a three-dimensional geodetic coordinate and gesture information of a total station point are obtained by using the method of non-horizontalization free established station for the total station; (3) the total station measures a point to be tested by the non-horizontal working gesture, and obtains the three-dimensional geodetic coordinate of the point to be tested through the measurement method of a non-horizontalization project of the total station. The invention solves technical problems of establishing a station, lofting and measuring only after flattening the total station in advance during project measurement, realizes the non-horizontalization free established station for the total station and project measurement of the non-horizontalization free established station; operation is simple; efficiency of field lofting and measuring works can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of engineering survey and relates to a method for setting up a total station. Background technique [0002] Modern total stations can not only measure distance and angle automatically, but also complete the processing of relevant information, such as the calculation of horizontal distance, height difference, elevation, coordinates, etc., and related applications such as station setting and stakeout. Indispensable high-efficiency, high-precision measuring instruments. At present, the methods for freely setting up total stations mainly include the method of resection of one side and one corner, distance resection of two sides, and resection of bilateral single corner. These free station setting methods are widely used in engineering practice. However, at present, the free station setting and measurement methods in engineering are based on the total station in the level state, and cannot be completed in the n...
