Matching of thermal and color images with application to power distribution line fault detection
Ha-Hyoung Jung, Joon Lyou · 2015
In this study, we developed a diagnostic system for power distribution lines based on a thermal imaging camera and a color camera. We propose a camera calibration method that shows two images, one from the color camera and the other from the thermal imaging camera with different FOVs, on the screen at the same time. We used the stereo camera calibration method to account for the different characteristics of the two cameras. The cameras were calibrated with the camera calibration tool. From our experiments, the performance and utilization of the proposed distribution line diagnostic system can be evaluated by transforming the thermal images through the intrinsic matrix and the extrinsic matrix.
