In recent years, the road paving industry has been facing a shortage of engineers with advanced pavement technology. In particular, temperature control technology for asphalt road paving is a very advanced technology that requires prediction of temperature changes in hot mix asphalt and compaction based on such predictions. Therefore, this research aims to inform road pavement construction by measuring the road surface temperature and generating a thermal distribution map that reflects the temperature change of the hot asphalt road surface. This paper describes the development of a system that measures the road surface using a thermal camera mounted on a road roller, projects the thermal camera image onto the ground based on the position and attitude estimated by RTK-GNSS, and generates a thermal distribution map of the road surface. The system was tested in an environment simulating road pavement construction, and the effectiveness of the implemented system was confirmed.
