摘要

本文提出了一种利用数字图像处理技术将光斑之间的位置变化转换为位移值的方法。考虑到精度和实际工程环境，利用工业激光源产生光斑，利用工业数码相机作为传感器采集目标微小位移的图像。将图像二值化作为一种数字图像处理技术应用于该算法，并利用最小二乘拟合实现图像信息到位移信息的转换。仿真实验和数据处理验证了该方法的有效性。

Displacement Measurement Based on Computer Vision

In this study, a method to convert the position changes among light spots into displacement values by using digital image processing is proposed. Considering the precision and practical engineering environment, light spots are produced by an industrial laser source, and industrial digital camera is used as sensor to collect images with tiny displacements of target. The image binarization as one of digital image processing techniques is applied to the algorithm developed, and the least square fitting is used to achieve the transformation from image information to displacement information. Several simulation experiments and data processing were carried out to validate this method.
