An Image-Based Automatic Gem Counting Device

Abstract

The invention discloses an image-based automatic gemstone counting device, which includes a frame, a feeding device, a feeding device and a collecting device installed on the frame, the feeding device is located at the feeding end of the feeding device, and the collecting device is located at the feeding device The discharge end; the feeding device includes a feeding box and a feeding roller, and at least one row of gemstone accommodation holes is arranged around the outer surface of the feeding roller along the circumference of the feeding roller, and each row is provided with There are several gemstone receiving holes and extend along the axis of the feeding roller; an image acquisition device is arranged at a position corresponding to the upper part of the feeding device. The whole process of counting the number of gemstones in the present invention is automated. By setting gemstone accommodation holes on the feeding roller, the gemstones are dispersed and the number of gemstones is controlled, and then the number of gemstones is automatically calculated by the camera and image processing system to improve the counting accuracy and achieve Fully automated points for gems.

Description

technical field [0001] The invention relates to a gemstone counting device, in particular to an image-based automatic gemstone counting device. Background technique [0002] Gem counting is an indispensable and important link in gem batch transactions. According to market research, gemstone counting currently on the market mainly counts the particles of gemstones by artificially borrowing a small counting board under glare lights. In 2010, Shanghai Guan Leming Co., Ltd. applied for a jewel bearing counter with application number 200910258273.5 (announcement number CN101739599 B). This kind of counter has high counting efficiency and low error rate, but it is mainly suitable for jewel bearings whose thickness is much smaller than jewel bearings. The height of the bearing, and the number of gemstones obtained must be in multiples of the corresponding scale of the capacity plate. Contents of the invention [0003] In view of the above deficiencies, the present invention pro...
