Static infrared thermal image processing-based underground pipe leakage detection method

A static infrared thermal image processing-based underground pipe leakage detection method, belonging to the technical fields of image depth processing and leakage detection. Greyscale information and temperature information of an underground pipe internal environment is acquired by introducing infrared thermal imaging, the greyscale information implements a conventional target for pipe internal pipeline state identification, and the temperature information is used for performing pipe leakage detection and provides a reference for subsequent repair and maintenance.
