摘　　要：针对焊接中的热变形测量的问题,提出基于视觉方法来进行检测的方案,并进行理论推算,证明了该方法的可行性。通过利用数码拍照为试验手段来代替视觉的方法,且对获得图像提出了基于MATLAB图片处理及测量的算法,对比得出焊接变形。结果表明:MATLAB算法提出的结果能和理论推导相符合,采用视觉测量方法能检测焊接变形。According to the problem of the thermal deformation measurement in welding,the vision-based method was proposed and theoretical calculation was made to prove its feasibility.By replacing visual methods with the use of digital photos as experimental methods and the image processing and measurement algorithm for pictures was proposed obtained to obtain welding deformation through comparison based on MATLAB. The results show that results by the proposed algorithm coincide well with the theoretical deduction and it is feasible to test the welding deformation with visual measurement method.
