摘要
研究基于计算机图像法运用激光测量物体位移及应变的方法。两个正交的图像记录系统,在试件产生位移后,记录试件被多束光所照射形成的图像。图像输入计算机,利用记录光路系统的几何参数,计算得试件上诸光点所产生的位移或应变大小。由误差修正理论,给出各位移的不确定度。实验结果证明测量方法是正确的。
Study on measurement for measuring displacement and strain of object by use of laser based on computer image.After the object with some measured light points,comes into being displacement and strain,images of the measured object are simultaneity recorded in two X,Y-directions using two orthogonal image-record systems.Based on the technique of computer image processing,the displacements or stain of every measured point may be obtained with the help of parameters of the optical system.In addition,with the the...
