Prawns quality detecting and classifying device based on machine vision technology

Abstract

The invention discloses a prawns quality detecting and classifying device based on a machine vision technology. The prawns quality detecting and classifying device based on the machine vision technology include a laying-off system, an image acquisition system, a classifying mechanism, a conveyor belt, a computer system and a controller system. A camera is fixed at the top end of a lighting box which is fixed above the conveyor belt, and a white unsmooth coating is painted on inner walls of the lighting box. Light source is light-emitting diode (LED) soft strip type light source belts which are distributed on four inner walls of the lighting box. Light source illuminates upwards, and reflects to the surface of the prawn through the white coating of the inner walls. After processing the collected image in a real time, the computer obtains corresponding information of the quality characteristic of the prawns and classifies that, and then controls a spray valve through a controller. Passing through a corresponding spray valve, the prawns with a different quality classification are blown into a corresponding collecting groove, while the prawns not blown by the spray valve directly drop into the collecting groove arranged at the ends of the conveyor belt. The prawns quality detecting and classifying device based on the machine vision technology can detects and classifies the prawns with different quality classifications by quickly and accurately detecting the morphology and color characteristic of the prawns.

Description

technical field [0001] The invention relates to a detection and grading device, in particular to a prawn quality detection and grading device based on machine vision technology. Background technique [0002] my country is a large aquatic product country in the world, and the export of aquatic products occupies a very important position in my country's agricultural product exports and foreign trade exports. However, there are still many problems in my country's aquatic product industry, and the overall quality of the products is not high. Shrimp is a major force in aquatic products, and its quality testing and grading is conducive to improving the export efficiency of prawns, which has positive practical significance. In the current production and life, both sides of the trade mainly judge the grade of prawns based on their external quality, such as size, shape, color, integrity and other indicators. Therefore, it is very necessary to classify prawns according to their extern...
