Abstract

The invention discloses a measuring method and system of angular deformation for line heating and cooling. A physical architecture used in the method comprises a display device, a data processor, a data storage and a three-dimensional profile measurer. The method is characterized in that three-dimensional point cloud data of a steel plate before and after line heating and cooling is processed, and angular deformation of a part near each flame path is calculated; specially, the method includes: target extraction of the point cloud data, denoising, data interpolation, flame path recognition, measuring point extraction and automatic calculation of angular deformation. Therefore, the measuring method and system has the advantages that automatic measurement of angular deformation of the flame path for line heating and cooling is provided, and basis for automatic correction of line heating and cooling process forecasting system is provided.

Description

technical field [0001] The invention relates to the technical field of automatic measurement of the deformation of a water-fired bending plate, in particular to a method and system for measuring the angular deformation of a water-fired bending plate, which is mainly used for measuring the angular deformation near the flame path behind the water-fired bending plate. Background technique [0002] The automation of the water and fire bending process is a necessary means to improve production efficiency, reduce labor intensity and reduce energy consumption. However, to realize the automation of the water-fired bending process, two key problems must be solved, namely, the automatic generation of the flame track and the prediction of the processing parameters. [0003] At present, relevant research institutions at home and abroad have achieved certain research results on the automatic generation of process parameters. For example, Dalian University of Technology conducts analysis...
