基于OpenCV的双波长光纤导引光在高精度装调上的应用
Application of dual-wavelength fiber guided light based on OpenCV in high-precision assembly and alignment
摘要
Abstract
In order to ensure the successful application of dual-wavelength fiber-optic light in high-precision alignment equipment,an image processing algorithm based on OpenCV(Open-Source Computer Vision Library)was designed.The active adjustment exposure mode is used to actively adjust the focus of the CCD(Charge-coupled Device)camera,OpenCV is used to analyze typical image processing algorithms.Through computer analysis of algorithms,adjustment of parameters,fitting of images and drawing of center coordinates,an ideal image is output.After detection and analysis,the average accuracy of image calibration is 4.54 μrad.This algorithm can capture,identify,and track targets in real time,and print the center coordinates recognized by the computer onto the output image,thus improving the accuracy of the installation and adjustment of the dual-wavelength optical fiber guide light and realizing dual-wavelength optical fiber guidance.关键词
