【摘要】 介绍了使用面阵CCD和基于PCI总线的图像采集卡为硬件电路,MATLAB和VISUAL C~++为软件核心组成的分立式万能工具显微镜目镜自动读数装置,实现在电脑屏幕上实时显示采集到的图像,得到所选图形的测试结果。系统通过软件控制图像的存储,利用最大类间方差法二值化、放大、调平、滤波、灰度均衡等方法处理图像,由模板匹配方法识别出最后的数字,实现了自动采集和自动识别读数。更多还原

【Abstract】 This paper describes an independent data auto-acquisition and reading system for eye lens of universal tool maker’s microscope. The system mainly includes two parts,the hardware and the software. The hardware part mainly includes a matrix CCD and an image acquisition card. And the software part is realized by hybrid programming with MATLAB and VC. Using this system,the view field of eye lens can be real time displayed on computer screen and be saved as an image under the control of the software. Moreover, the image is processed using such image processing methods as enlarging,filtering,histogram equalization and horizon control,and the result can be recognized rapidly through Template matching.更多还原
