Abstract
Disclosed is a thermal-based automatic roller tracking and mapping system for roller path tracking and mapping in pavement compaction. Accuracy in estimation during roller position tracking and mapping for pavement compaction through the use of thermal imaging is achieved. The tracking and mapping system utilizes an infrared camera for automatic roller path tracking and mapping in pavement construction. The tracking and mapping data associated with the movement of the roller vehicle during compaction of the surface can be generated and visually represented in a user interface accessible to the operator of the roller vehicle. Based on the tracking and mapping data that is generated in real-time and presented to the operator in the user interface, the operator can make adjustments to the roller vehicle and path, as necessary.
