Method, this method principle are simple, it is easy to accomplish, versatile, the feature recording device designed according to this method can hold very much
It easily realizes, and is installed on Gemstone Identification instrument, and can satisfy the observation, measurement and identification of jewel crown, and be easily achieved
The requirement of automation；
(2) lateral feature of jewel different angle can be acquired, and together with crown feature by the rotation of objective table in the present invention
Record has certain uniqueness as the proof of identity in the jewel process of circulation；
(3) can be according to the type and characteristic of jewel in the present invention, the brightness of ring light, first light source and second light source, the first one-tenth
As the image acquisition parameter of camera lens and the second imaging lens, the settable adjustment of the size of the aperture of the diaphragm and the spy for being cured as jewel
Acquisition parameter is levied, is achieved with the crown and side image of jewel.
