基于图像处理的光纤测量方法研究

Fiber Measurement Based on Image Processing

为研究光纤显微图像,将计算机数字图像处理技术引入到光纤形态分析中。首先将光纤端面经显微光学系统成像,由CCD摄像头接收,并通过图像采集卡传至计算机;然后对光纤的数字图像进行处理,其中包括对比度增强、图像的滤波、图像的二值化、图像分割等;最后通过严格的计算,得到光纤的各种参数。此系统的软件用C++Builder5语言写成。程序中采用了Parodax数据库及BDE技术,并提供了结果报表和二、三维图像显示。

A computer digital image processing technique is introduced into fiberoptic morphological analysis. The end face of the optical fiber is imaged by a microscopy, recorded by a CCD camera, and transferred by the image grabber into a computer. Then some proprocessed methods including contrast enhancement, image filtering, thresholding, and segmentation are used to process the digital image of the fiber. According to further analysis and calculation, various parameters of the fiber are obtained. Combined wit...
