Description

technical field [0001] The invention belongs to the application of infrared thermal imaging technology and digital image processing technology in the precise positioning and detection of leakage points such as walls or containers, and is mainly suitable for the positioning and detection of wall leakage sources. Background technique [0002] When maintaining and managing various buildings, it is of great engineering application value to find liquid leakage points through surface nondestructive inspection. However, it is often difficult to find leakage sources and leakage paths through conventional methods. Water seepage damage is continuous, causing premature damage to building materials, equipment and decorative furniture, and causing indoor air pollution. Especially the point of infiltration is difficult to determine, because water often does not seep in the expected path, and no trace of water seepage can be seen with the naked eye. It is extremely necessary to diagnose w...
