Description

Technical Field

[0001] The utility model relates to the technical field of road monitoring, in particular to a real-time road condition monitoring module based on infrared thermal imaging. Background Art

[0002] Infrared thermal imaging uses photoelectric technology to detect specific infrared wavelengths emitted by objects, converting these signals into visually discernible images and graphs, which can then be used to calculate temperature values. This technology transcends visual barriers, allowing people to "see" the temperature distribution on an object's surface. Consequently, infrared imaging has gained widespread application in road inspections.

[0003] Existing real-time road condition monitoring modules based on infrared thermal imaging are fixed in position after installation. Changes in factors such as air humidity will affect the accuracy of the infrared imaging monitoring module. Since the infrared imaging monitoring module is fixed in position, the height cannot be changed to compensate for the reduced accuracy caused by high air humidity. Utility Model Content
