Zainul Abdin Jaffery, Ashwani Kumar Dubey . Testing and Calibration of Temperature Gauges using Webcam based Non-Invasive Technique. International Journal of Computer Applications. 79, 1 ( October 2013), 41-47. DOI=10.5120/13709-1462
In this paper, a contact less testing and calibration system is developed for temperature gauges. The system captures the images of temperature gauge at a regular interval, detects the desired region of interest using algorithms and segments the needle for further processing. The segmented image properties are calculated and matched with the standard data to indentify the indicated value. The system is capable enough to generate alarm and emboss 'defective sample' on the gauge under test. In the field manufacturing, non invasive visual inspection systems are replacing the need of human inspector to prevent the inclusion of incorrect parts or to check the quality of goods.
