The Vehicle Hotspot Detection System profiling system combines thermal imaging cameras and 2D LiDAR sensors to detect overheated vehicles. The system can be used to detect and divert these vehicles, for example before entering tunnels, before being transported by RoRo ships, at road-rail loading terminals, or at traffic control areas. The system measures the temperature and dimensions of each vehicle, determines the vehicle class and generates a 3D model of the vehicle. This allows individual vehicle zones, such as the wheels, motor, exhaust pipe or cargo hold, to be automatically identified.
