Method for performing inter-conversion between survey coordinates and construction coordinates

Abstract

The invention relates to a method for performing inter-conversion between survey coordinates and construction coordinates. The method specifically comprises the following steps of: obtaining designed positioned survey coordinates of a building by a designing institute; converting all survey coordinates needing lofting through Excel software by using a computer, wherein a construction coordinate system conversion equation needs using in the conversion process of all the survey coordinates; converting the survey coordinates into coordinates which are parallel to and vertical to the building by using the construction coordinate system conversion equation, wherein the azimuth angle of a distance between two points on the same axis in the coordinate system is surely one of 0 degree, 90 degrees, 180 degrees and 270 degrees despite that the two points are on the same vertical axis or the same horizontal axis, and one of the values of the two points (A, B) on the same vertical axis or the same horizontal axis is surely the same; determining converted data into the construction coordinates after the converted data is verified as correct and lofting by using the construction coordinates. Due to the adoption of the method, a computing formula can be simplified, fast computation is realized and the correctness of a computed result is enhanced.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, and in particular relates to a mutual conversion method between measurement coordinates and construction coordinates. Background technique [0002] The traditional building positioning measurement method is: directly use the measurement coordinates provided by the design institute to carry out the measurement. Generally, there is a certain angle between the measurement coordinates and the vertical and horizontal axes of the building. In the process of setting out, it is often necessary to calculate two The azimuth and distance between the points are checked to ensure the accuracy of the data, so the calculation workload will be very large, which will inevitably have a certain adverse effect on the accuracy of the data. [0003] Therefore, it is necessary to develop a new building location measurement method. Contents of the invention [0004] The technical problem to be solved ...
