基于虚拟仪器技术的活塞表面字符识别

Character Recognition of Piston Surface Based on Virtual Instrument Technology

应用IMAQVision工具包在LabVIEW虚拟仪器平台上开发了识别活塞表面字符的机器视觉系统。该系统通过适当的图象处理和分析,如模板匹配、图象校正、图象提取、阈值分割、形态学膨胀、腐蚀以及光学字符识别等技术,能够实现活塞表面字符的自动检测与识别。实验证明,该系统具有一定的实用性和通用性。

Machine vision system to recognize charaeters of piston surface is developed in LabVIEW （a virtual instrument platform）with IMAQ Vision toolset,The system can automatically inspect and recognize characters of piston surface by properly image processing and analyzing technology such as pattern matching ,image calibration,image extraction,threshold segmentation,morphology,optical character recognition and so forth,The experiments prove that the system is practical and universal.
