Problems solved by technology

[0002] At present, there are two main methods for grading potatoes. One is to use vibrating mesh grading equipment, drum grading equipment or flat fan rotary roller grading equipment to classify and screen potatoes according to their diameter. Therefore, it is only suitable for the sorting of potatoes with regular shapes, and it is easy to cause wrong grading for potatoes with irregular shapes; the other is to classify according to weight, and use pressure sensors or balances to obtain potatoes The weight information of the potato is graded and screened through the control circuit or the principle of physical mechanics, but this method can only be graded by weight, and cannot judge the size and shape of the potato
Therefore, both methods fail to achieve intelligent grading of potatoes based on 3D reconstruction

Abstract

The invention discloses a potato quick nondestructive testing and automatic grading device and method. The automatic grading device comprises a climbing roller shaft conveying device, a transverse conveying belt and a grading output device; and the climbing roller shaft conveying device, a soil removing conveying device, the transverse conveying belt, a longitudinal conveying belt and a grading output device are sequentially connected, and a light sorting device is arranged between the longitudinal conveying belt and the grading output device. By means of the potato quick nondestructive testing and automatic grading device and method, the four-eye stereoscopic vision technology is adopted, and a computer vision hardware system for potato external quality nondestructive testing is built according to three indexes including the weight, the potato shape and the external defect; after the potatoes are subject to outer surface cleaning, external characteristics of potatoes are restored through the four-eye stereoscopic vision technology, defective and abnormal potatoes are screened out, then the different potatoes are conveyed into corresponding grading boxes according to the mass of the potatoes, and potato quick, real-time, objective and nondestructive testing and grading are achieved.

Description

technical field [0001] The invention relates to a grading device and method, in particular to an automatic grading device and method for quick and nondestructive detection of potatoes. Background technique [0002] At present, there are two main methods for grading potatoes. One is to use vibrating mesh grading equipment, drum grading equipment or flat fan rotary roller grading equipment to classify and screen potatoes according to their diameter. Therefore, it is only suitable for the sorting of potatoes with regular shapes, and it is easy to cause wrong grading for potatoes with irregular shapes; the other is to classify according to weight, and use pressure sensors or balances to obtain potatoes The weight information of the potato is graded and screened through the control circuit or the principle of physical mechanics, but this method can only be graded by weight, and the size and shape of the potato cannot be judged. Therefore, both methods failed to achieve intellige...
