A Computer Vision Measurement System for Linear Deformation of Line Heating

Abstract:

Line heating is an important technique for processing hyperboloidal outside plate of ship hull. To realize the automation of the line heating, the deformation rule in line heating should be researched. In this paper, the computer vision measurement technique is applied to find out the disciplinarian of linear deformation in line heating. The principle of computer vision measurement is firstly introduced in this paper. The emphases are the images collection, camera calibration, edge detection, and 3D data reconstruction. Then some key techniques for ensuring the measurement precision are presented. At last, the result of experiments is given. The experiments showed that the measurement system was valid for measuring the linear deformation of line heating.
