光学测量三维测振双目视觉多点匹配 optical measurement 3D vibration measurement binocular vision multipoint matching

摘要

振动测量是现代制造业发展的关键技术之一, 在**、工业、农业等方面具有重要的应用意义。为了实现大视场、高效率的非接触式测量, 基于双目视觉原理设计了一种多点三维振动测量系统。在待测物体表面粘贴多个标志点, 对左右相机图像上的标志点进行多点同步准确匹配计算得到其空间三维坐标, 实现三维测振。选取五个标志点进行实验, 结果表明, 测量误差最大为91μm/m, 可满足大多数振动测量的要求。

Abstract

As one of the key technologies in the development of modern manufacturing industry, vibration measurement has many important applications in military, industry and agriculture. In order to realize non-contact measurement with large field of view and high efficiency, a multi-point 3D vibration measurement system based on binocular vision was designed. By pasting feature points on the surface of the tested object, and performing a multipoint and synchronous matching on the left and right camera images exactly, the coordinates of the three-dimensional space can be obtained to realize 3D vibration measurement. Five feature points was selected, and the experimental results show that the maximum measurement error is 91um / m, which can meet the requirement of most vibration measurement.
