Abstract

The invention provides a railway canopy three-dimensional structure measurement and deformation analysis method, which comprises the following steps that a plurality of detection points are deployed to detect a railway canopy three-dimensional structure, and each detection point is provided with a transverse rotation steering engine, a longitudinal rotation steering engine, a laser radar range finder and a control mainboard; the laser radar range finders are bound on the transverse rotation steering engine and the longitudinal rotation steering engine, and range finding of different point positions is carried out according to rotation of the transverse rotation steering engine and the longitudinal rotation steering engine during dynamic point position measurement; data control lines of the transverse rotating steering engine and the longitudinal rotating steering engine are respectively connected with the control mainboard; the control main board is connected with the server-side upper computer through the cooperation of a network cable and a switch, and is controlled by the server-side upper computer; a lower computer connected with the server-side upper computer is configured on the control mainboard, and the lower computer comprises an IP and a port of the lower computer; the current state of the railway canopy can be checked in real time, early warning can be carried out in advance according to analysis data, and the state can be displayed to a user for reference in a three-dimensional mode.

Description

technical field [0001] The invention relates to the technical field of three-dimensional structure measurement and deformation analysis of a canopy, in particular to a three-dimensional structure measurement and deformation analysis method for a railway canopy. Background technique [0002] The structural form of the railway canopy is constantly developing and changing with the development of railway construction and the progress of building technology materials. At present, it is impossible to check the current status of the railway canopy in real time, which has great potential safety hazards during use. Contents of the invention [0003] The object of the present invention is to provide a three-dimensional structure measurement and deformation analysis method of a railway canopy, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [000...
