摘要:
为了方便地获取物体表面的三维形貌,提出了一种基于面内位移测量和刚体旋转2个要素的测量方法.利用与计算机连接的步进电机精确控制物体的旋转,分别采用电子散斑干涉法和数字图像相关法测量旋转物体产生的面内刚体位移,根据位移计算出物体表面各点的相对高度,进而得出物体的三维形貌.采用该方法对边缘有倒角的半圆柱试件进行了测量,并将测量结果与游标卡尺的测量值进行对比,二者非常接近.实验结果表明,电子散斑干涉法测得的最大误差小于1.20%,数字图像相关法测得的最大误差小于1.75%,由此证明了该方法的有效性和可靠性.
Abstract:
A novel method based on in-plane displacement measurement and rigid body rotation was developed to measure the 3D shape of an object conveniently. The stepping motor connected with a computer was used to rotate the specimen with high precision. The in-plane displacements were measured by the electronic speckle pattern interferometry(ESPI)method and the digital image correlation(DIC)method, respectively. The relative depths of points on the objects surface were calculated according to the displacements, and then the 3D shape of the object can be obtained. A cylinder with chamfered edges was measured by the proposed method. And the measurement results were in good agreement with the data obtained by the venire caliper. The experimental results show that the maximum difference by the ESPI method is less than 1.20% and that by the DIC method is less than 1.75%, proving the methods availability and reliability.
