摘要
基于机器视觉技术,结合工业温度计的实际检定环境,研制了水银温度计自动读数系统。介绍了该自动读数系统的光学系统设计和实现,并给出了图像处理方法和过程。实验结果表明,该系统读数精度可小于0.1℃,达到了设计目标,满足应用的要求。
Based on machine vision techniques, the automated reading techniques of mercury thermometer were studied. According to the basic principle and working process, the selection of lens, imaging sensor, lighting source and algorithms were presented. An experiment system was developed and the on-site experiments at 0 ℃ and 100 ℃ were finished. The experiment results show that this reading technique can achieve total automated measurement and it offers high precision and efficiency, which shows the potential applications in industry.
