摘要
提出一种LabVIEW与机器视觉相结合的数码管数字识别方法。应用IMAQ Vision工具包在LabVIEW虚拟仪器平台上开发了识别数码管数字显示的机器视觉系统。该系统通过适当的图象处理和分析,如图像去噪、阈值分割以及光学字符识别(OCR)等技术,能够有效识别数码管显示的数字。
This paper proposes a method to recognize digitals of digital tube with LabVIEW and machine vision combined. Machine vision system is developed in LabVIEW (a virtual instrument platform) with IMAQ Vision toolset to recognize digitals of digital tube. The system can effectively identify the digitals of digital tube through appropriate image processing and analysis, such as image denoising, threshold segmentation and optical character recognition (OCR) technology.
