System and Method to Automatically Generate Valuable Cutting Plans for a Rough Gemstone

摘要

A system and method to automatically generate valuable cutting plans for a rough gemstone is disclosed. An apparatus having a gemstone holding fixture holds the rough gemstone to be evaluated. Camera captures multiple external images of the rough gemstone being rotated and illuminated. A three-dimensional external image of the rough gemstone including external imperfections is generated using a software governed image processing device. After immersing the gemstone inside a medium that has a refractive index substantially same as that of the gemstone, camera captures multiple internal images of the rough gemstone being rotated and illuminated. Three-dimensional images of impurities inside the rough gemstone are generated and combined with the three-dimensional external image of the rough gemstone. Correct locations, shapes, and sizes of the internal impurities and external imperfections of the rough gemstone are identified. Software governed image analysing device computes three-dimensional cutting plans and selects the most valuable cutting plan while evaluating the worth of the rough gemstone using real-time artisan data.
