Total station networking measurement method of large-scale structural component

[0024] Its specific scheme of the method for measuring large structural parts by total station network of the present invention is as follows, see image 3 as shown,

[0025] (1) Before measurement

[0026] Set the main station total station 1 and the auxiliary station total station 2 on both sides of the large structural part 3 to be measured; determine three measuring points on the large structural part 3, and place a positioning prism, according to the three measuring points and passing Determine the user coordinate system of the main station by the method of surface-line-point; determine several reference points q between the total station 1 of the main station and the total station 2 of the auxiliary station, and around the large structural part 3 1...q n , and place the positioning prisms one by one, the reference point q 1...q n Include the master station user coordinate system, use six or more of them as the reference points for setting up stations, and measure their coordinate values, and the reference points for setting up stations can be measured by the auxiliary station total station 2 at the same time; The reference point is to establish the user coordinate system of the auxiliary station through the coordinate orientation method; the total station 1 of the main station and the total station 2 of the auxiliary station respectively measure and record other points other than the reference point for setting up the station, which can be controlled by the total station 1 of the main station and the total station 2 of the auxiliary station. The reference point coordinates measured by station total station 2 at the same time, the coordinate values ​​of the master station user coordinate system and the auxiliary station user coordinate system coordinate values ​​of these reference points are substituted into the seven-parameter coordinate conversion equation to obtain the conversion parameters: coordinate translation amount X 0 , Y 0 ,Z 0 , Coordinate rotation ω x , ω y , ω z , Scale coefficient m.

[0027] (2) When measuring

[0028] The master station total station 1 and the auxiliary station total station 2 respectively measure the measurement points on the large structural parts 3 that can be measured respectively, wherein the measurement data of the master station total station 1 is directly used as the measurement result; the auxiliary station total station 2 Measurement data (X 1 , Y 1 ,Z 1 ) is transformed into the coordinate value (X 2 , Y 2 ,Z 2 ) becomes the measurement result, the total station 1 of the main station and the total station 2 of the auxiliary station jointly complete the measurement of the large structural part 3 as a whole.

[0030] Where: X 1 , Y 1 ,Z 1 is the coordinate value of the measurement point in the user coordinate system of the auxiliary station, X 2 , Y 2 ,Z 2 is the coordinate value of the measuring point in the user coordinate system of the master station, X 0 , Y 0 ,Z 0 is the coordinate translation, ωx, ωy, ωz are the coordinate rotation, and m is the scale coefficient.
