Fresh cut flower sorting device and method based on RealSense camera

Abstract

The invention discloses a fresh cut flower sorting device and method based on a RealSense camera, and belongs to the technical field of fresh cut flower sorting. The device comprises an industrial personal computer, a conveying device, a detection device and a sorting device, wherein the detection device comprises a laser sensor and an image acquisition device, the image acquisition device comprises a light source, a RealSense camera and a turnover device, two-dimensional images and depth information of fresh cut flowers are collected through three RealSense cameras, size features and color features of the two-dimensional images are obtained through an image processing algorithm, the two-dimensional images and the depth information are analyzed through a deep learning algorithm to obtain the maturity of the fresh cut flowers, the features of multiple fresh cut flowers are integrated, the fresh cut flowers are classified through a classification algorithm, and finally, the fresh cut flowers are classified into three types to be collected through a sorting device. According to the method, feature extraction can be carried out on different grades of the fresh cut flowers, sorting is carried out, and the efficiency of identifying, grading and sorting the fresh cut flowers is improved.

Description

technical field [0001] The invention belongs to the technical field of fresh-cut flower sorting, and in particular relates to a fresh-cut flower sorting device and method based on a RealSense camera. Background technique [0002] Fresh cut flowers are one of the eight important industries in Yunnan. Yunnan has become the region with the fastest growing flower area and output value in the world, and the world's largest fresh cut flower production place. The production area and output of fresh cut flowers rank first in the world, and the output value ranks second in the world. . Dounan Kunming Flower Auction Center has a daily transaction volume of 3-3.5 million branches, and the peak daily transaction scale has exceeded 7 million branches. Millions of fresh-cut flowers are sent from Dounan, Kunming to all over the world every day. However, the sorting process still relies on a large number of manual sorting. During the implementation process, there are not strict implementat...

Problems solved by technology

However, the sorting process still relies on a large number of manual sorting. During the implementation process, there are not strict implementation of fresh-cut flower grading standards, or due to differences in manual sorting judgments, there are outstanding problems such as inaccurate grading and low quality of fresh-cut flowers, which hinder the fresh-cut flowers. The increase in the added value of cut flower products has been increasingly unable to meet the needs of fresh cut flower preservation period, logistics and transportation, rapid growth in market demand, and industrial added value to be improved.
