Introduction
TAMS™ is a new way of quantifying appearance quality inspired by a four-year collaboration between Rhopoint, Volkswagen AG and AUDI AG. This innovative new technology models the human perception of surface appearance quality, providing new parameters that revolutionise the understanding and communication of visual appearance information.
TAMS™ Concept
Dual focus camera operation captures ALL surface appearance data.
FAST operation with powerful on board image processing.
Easy to use with on screen menu navigation prompts.
SAFE to use- static measurement with soft contact area.
ERGONOMIC operation-measure entire vehicle more easily.
FAST & EASY data transfer via SD card.
Flexible power options – 2x removable rechargeable battery or mains operation.
Enhanced process integration via RFID.
