Abstract

The invention belongs to a method for identifying gemstones, in particular to a novel gemstone imaging and characteristic recording method. In the novel gemstone imaging and characteristic recording method, a gemstone, a first light source, an objective table, a diaphragm, a beam splitter prism, a second light source, a first imaging lens, a first lens moving table, a second lens moving table anda second imaging lens are used. During use, the gemstone is putted on the objective table, and the first light source and the second light source are opened for imaging; meanwhile, parasitic light iseliminated by the diaphragm; the first imaging lens and the second imaging lens are respectively adjusted by the first lens moving table and the second lens moving table; besides, coronal and lateralimages of the gemstone are acquired, and coronal and lateral characteristics of the gemstone are recorded and archived.

Description

technical field [0001] The invention belongs to a gemstone identification method, and more particularly relates to a gemstone imaging and feature recording method. Background technique [0002] At present, in the circulation process of gemstones or diamonds, identification certificates issued by professional institutions and individuals are mainly used as the basis, but identification certificates are easy to be counterfeited and lost, and their uniqueness cannot be proved. Some institutions use lasers to engrave markings and numbers on the girdles of gemstones and diamonds as identification for gemstones. However, this method is easy to be counterfeited and tampered with, and uniqueness cannot be determined. [0003] Therefore, the present invention takes the feature recording of gemstones as the research object, and proposes a way to use light source imaging, and use two lenses to simultaneously collect the crown and side images of gemstones, and record them as features t...
