Classification: CPC G  H | IPC G  H

Claim 9:
10. A system for verifying identity of a stone under test (SUT), the system comprising:
a programmable controller,
one or more image sensors, and
one or more broadband visible (BBV) light sources;
wherein:
the one or more image sensors being operable, by the programmable controller, to perform a first scanning of the SUT and capture a first plurality of images at different positions of the SUT about a rotational axis of the SUT;
the one or more broadband visible (BBV) light sources being operable, by the programmable controller, to illuminate the SUT from different angles or elevations, while the one or more image sensors being operable, by the programmable controller, to perform a second scanning of the SUT and capture a second plurality of color-measurement images at different positions of the SUT about the rotational axis of the SUT;
the programmable controller being configured and operable to:
utilize the first plurality of images for calculating a 3D volumetric model of the SUT; and
process the SUT 3D volumetric model and the plurality of color-measurement images to generate SUT color data; and
compare SUT data comprising the SUT 3D volumetric model and the SUT color data to corresponding previously-obtained reference data of the SUT to verify the identity of the SUT.
