Abstract
Aiming at the complex environment in the inspection of underground heating pipes, including high-temperature flanges, valves, and stale water stains on the surface of heat pipes, a method for detecting water leakage in heating pipelines combining thermal infrared and visible images is designed. Temperature anchor frame detection is performed on thermal infrared images, and deep learning is used for visible image for water stain anchor frame detection. This paper proposes a detection method for determining the degree of correlation and high temperature point to determine the water outlet point based on the position coincidence degree, which excludes the infrared interference caused by the high temperature of the flange and valve, and the visible light interference caused by the old water stains, and has a good detection result for the leakage of the heat pipe.
