Disease detection device and method for asphalt pavement

Abstract

The invention discloses a disease detection device for an asphalt pavement. The disease detection device comprises a carrying trolley, an infrared image collecting part, a water tank, a water spraying mechanism, an embedded system and a satellite positioning system. The water tank and the water spraying mechanism are used for spraying water on the asphalt pavement. The infrared image collecting part is used for collecting an infrared image of the asphalt pavement on which water is sprayed. The embedded system is used for obtaining infrared image data of the infrared image collecting part and conducting color analysis on the infrared image data. When diseases on the pavement exist, color segmentation is conducted on the infrared image data, the types of the diseases of the pavement and the area of the disease area are determined, the current position data of the satellite positioning system are read, and a result is stored into a database. The invention further discloses a disease detection method for the asphalt pavement. The diseases on the asphalt pavement and the development state of the diseases are accurately and rapidly detected, the labor intensity of workers is relieved, the labor efficiency is improved, and the maintenance cost of the asphalt pavement is reduced.

Description

technical field [0001] The invention relates to a pavement defect and pavement state detection technology, in particular to an asphalt pavement defect detection device and method based on infrared thermal imaging technology. Background technique [0002] By the end of 2013, the total mileage of expressways in my country reached 104,468 kilometers, ranking second in the world. With my country's economic development and social progress, the total mileage of expressways is still increasing. With the increase of expressway mileage, expressway maintenance has become one of the key technologies for the healthy development of expressways. my country's highways are mainly asphalt pavement. How to quickly and accurately detect the health status of the asphalt pavement and provide a basis for highway maintenance is the current challenge for highway pavement testing. [0003] Existing asphalt pavement disease detection mainly relies on on-site human eye observation. Manual observatio...
