Automatic gemstone counting device based on images

Abstract

The invention discloses an automatic gemstone counting device based on images. The automatic gemstone counting device comprises a machine frame on which a material inlet device, a material feeding device and a collection device are installed. The material inlet device is arranged at the material inlet end of the material feeding device. The collection device is arranged at the material outlet end of the material feeding device. The material inlet device comprises a material supplying and material inlet box and a material inlet rolling shaft. The external surface of the material inlet rolling shaft is provided with at least one row of gemstone accommodating holes in a surrounding way along the circumferential direction of the material inlet rolling shaft. Each row is provided with multiple gemstone accommodating holes and extends along the axis of the material inlet rolling shaft. An image acquisition device is arranged at the upper position corresponding to the material feeding device. Automation of the whole gemstone quantitative statistical process is realized. Gemstones are dispersed by utilizing the gemstone accommodating holes arranged on the material inlet rolling shaft and the number of the gemstones is controlled, and then the number of the gemstones is automatically calculated by a camera and an image processing system so that counting accuracy is enhanced and full-automatic counting of the gemstones is realized.

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 CN101739599B). 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 that of jewel bearings. Height, and the number of gemstones obtained must be in multiples of the corresponding scale of the capacity board. Contents of the invention [0003] In view of the above deficiencies, the present invention provides an ima...
