A system and method for calibrating a vision system includes a selective wavelength interactive material located within the cabin of the vehicle and a control system in communication with the camera. The material is arranged as a pattern having pattern elements configured to reflect or absorb infrared light from an infrared light source. The control system is configured compare a captured image from the vision system that shows the pattern elements and calibrate the vision system based on a comparison of the captured image. Additionally or alternatively, the selective wavelength interactive material is disposed on a surface of a safety belt and the control system is configured to determine that an occupant seated in a seat is wearing a safety belt associated with the seat when the captured images show that the selective wavelength interactive material on the surface of the safety belt extending across the occupant seated.
