Automatic calibration system of thermo-hygrometers

Abstract

Machine vision technology is an interdisciplinary subject involving plenty of fields such as artificial intelligence, neurobiology, psychophysics, computer science, image processing and pattern recognition, etc. In recent years, with rapid development of the technology, machine vision recognition is widely used in many fields of detection and control. For thermo-hygrometers calibration, the manual operation method is used traditionally. This has proven to be a cumbersome, time-consuming, and error-prone activity, as there are lots of models and quantities of thermo-hygrometers to be calibrated. Therefore, an automatic thermo-hygrometers calibration system was developed by using vision recognition technology in combination with automatic movement control as well as a purposely structured database management software. It can complete the calibration and the verification task accurately, timely and efficiently. It has drastically reduced the workload, improved accuracy, and realized the automatic calibration of the thermo-hygrometers.
