Process diagram Software interface Software analyses diamond projections obtained from nine cameras, generates 3D image of the diamond, classifies it to the certain group depending on its shape and ensure that the crystal is ejected to the corresponding box.
9 diamond projections
Form of classification results
Operation Diamonds automatically come one by one from the feeding bin to the detection zone. Nine cameras take and transmit diamond projections to the software, which generates 3D image, defines diamond’s shape and assign each crystal to certain group. Then, the diamond comes into a cell of the receiving drum where it is ejected to the corresponding concentrate box.
