Basic Study of Air Leakage Position Based on Thermography Mosaic Technology

摘要

cqvip:When locating the leakage of thermal field of a certain container,it is hard for us to evaluate the leakage with one or several separate thermal infrared images.Instead,panoramic imagery with a wide visual angle and high distinguishability is always needed.However,we can only get images for part of the scene because of the limited visual field of thermography and the large size of the measured object in practical.What is more,the hardware that can be used to get panoramic images is always expensive and cannot be used in large scale.Therefore,this paper introduces image mosaic technology,which can be used to get the intact thermal infrared image of the measured and increase the efficiency of detection.The experiment results demonstrate its effectiveness.
