The invention relates to the technical field of high-speed rail vehicle body flatness measurement, and particularly discloses a flatness measurement and evaluation system based on line structured light, which comprises a line structured light visual sensor device, a data processing device, a three-dimensional reconstruction device and a motion device, the movement device is used for driving the linear structured light vision sensor device to move; the line structured light vision sensor device is used for performing image acquisition on a to-be-detected area on the surface of a train body; thethree-dimensional reconstruction device is used for performing three-dimensional reconstruction according to the motion parameters and the image information of the area to be measured; and the data processing device is used for controlling the movement of the movement device, controlling the image acquisition frequency of the structured light visual sensor device and performing flatness analysisaccording to the three-dimensional morphology point cloud data to obtain a flatness analysis report of the surface of the train body. According to the flatness measuring and evaluating system based onthe line structured light, automatic measurement and evaluation of the polishing quality of the high-speed rail body can be achieved.
Description
technical field [0001] The invention relates to the technical field of flatness measurement of high-speed rail bodies, in particular to a flatness measurement and evaluation system based on line structured light. Background technique [0002] As domestic high-speed rail construction is getting faster and faster, the demand for high-speed rail trains has increased sharply, which poses more severe challenges to the production and manufacture of high-speed rail trains. The high-speed rail body-in-white refers to the unpainted train body. The train body must be putty polished before painting to ensure the adhesion of the coating. The quality of the putty grinding of the high-speed rail body-in-white affects the operation of the high-speed rail to a large extent. When the wind resistance performance, its grinding quality is mainly judged by measuring the flatness of its surface. The biggest problem in the putty grinding process is to prevent the base material from being over-gri...
