AMAC is composed of three subsystems:
- Mobile system for data and image acquisition
- Detection, performance analysis and positioning software
- Management and analysis software
High sensitivity cameras installed onboard measure the luminance, even under low light conditions. The response curve of the cameras is equivalent to the human eye and allows luminance measurement consistency.
The cameras are geometrically calibrated to measure distances and dimensions. Together with the multiple sensors onboard, the geometry context of the retroreflectivity is measured. An LED illumination system is fully controlled to guarantee repetitive measurements Auxiliary sensors provide full information about environmental conditions, and all components are completely integrated through precise synchronization electronics to ensure constant and repetitive accuracy.
