Sorting device and method for recognizing size of litchi kernels based on machine vision

Abstract

The invention discloses a sorting device and method for recognizing the size of litchi kernels based on machine vision. The device comprises a rack, a conveying mechanism is laid on the rack, a samplefeeding mechanism is installed above the rear end of the conveying mechanism, and the conveying mechanism is provided with a machine vision device; a sorting mechanism is installed at the front end of the rack, a sorting upper channel and a sorting lower channel are arranged in the sorting mechanism, and a regulating mechanism is installed on the lower part of the sorting mechanism; and to-be-sorted litchis successively enter the conveying mechanism from the sample feeding mechanism, the litchis are successively conveyed to the sorting mechanism through the conveying mechanism, the size of the litchi kernels is detected through the machine vision device, detection results are sent to the regulating mechanism, and after the corresponding litchis reach the sorting mechanism, the regulatingmechanism regulates the position of the sorting lower channel according to the detection results, so as to guide the litchis into corresponding collection boxes through the sorting upper channel or the sorting lower channel. According to the sorting device and method, the structure is simple, operation is convenient, the cost is low, damage to pulp is avoided, and the sorting device and method issuitable for production lines.

Description

technical field [0001] This application relates to the field of mechanical automation, in particular to a sorting device and method for recognizing the size of litchi stones based on machine vision, which can be used for sorting the stones of all kinds of litchi, longan or other fruits. Background technique [0002] my country is a big litchi country. According to statistics in December 2018, the total area of ​​litchi planted in my country is 8.13 million mu, with an annual output of 2.296 million tons. However, lychee is a typical seasonal fruit with a concentrated ripening period and a short shelf life. During the lychee production period, oversupply tends to occur, resulting in some lychees being unsalable. Therefore, with the increase of lychee production, the sales products will inevitably become more and more diverse, and the sales channels will inevitably become wider and wider. Litchi will depend on deep processing, and processing equipment related to lychee will be...
