Embodiment Construction

[0059] A high-efficiency sunflower seed shelling method based on vision technology, using equipment including a shelling machine, a computer, and a video camera, is characterized in that: non-contact real-time detection of the shelling rate of the shelling machine.

[0060] Hulling sunflower seeds involves the following steps:

[0061] 1. Start the shelling machine and the camera, the sunflower seeds to be shelled enter the shelling machine for shelling, the camera captures the image in real time, and inputs the image into the computer for analysis and processing.

[0062] The image is preprocessed by a median filter to remove noise interference during image acquisition.

[0063] 2. The image is converted from RGB color space to HSV color space by computer, its H component and S component are respectively binarized by two-dimensional Otsu algorithm, and the V component and H component are combined to obtain the image of sunflower seeds and sunflower kernels Combining the V co...

Abstract

The invention discloses a method for efficiently shelling sunflower seeds on the basis of vision technologies. Equipment for implementing the method comprises shellers, computers and video cameras. The method for shelling the sunflower seeds is characterized by comprising steps of (1), starting the shellers and the video cameras, inputting images into the computers and analyzing and processing the images; (2), transforming RGB (red, green and blue) color spaces of the images into HSV (hue, saturation and value) color spaces by the aid of the computers, respectively binarizing H components and S components, combining V components and the H components with one another to obtain sunflower seed mark graphs and sunflower kernel mark graphs and combining the V components and the S components with one another to obtain hole mark graphs; (3), forming target general mark graphs from morphological gradient graphs obtained from the sunflower seed mark graphs, the sunflower kernel mark graphs, the hole mark graphs and the V components, carrying out de-noising processing on obtained images, estimating sunflower seed shelling rates in real time, transmitting instructions by the computers in real time and shelling the sunflower seeds. The method has the advantages that the kernel rate of the sunflower seeds can be increased, and the damage rate of sunflower kernels can be reduced.

Description

technical field [0001] The invention relates to a high-efficiency sunflower seed shelling method based on vision technology, belonging to the technical field of agricultural product processing. Background technique [0002] In recent years, with the advancement and development of technology, automated production equipment has come out continuously. As an important oil source and snack food, sunflower seeds have been widely used in shelling machines. The separation system of the shelling machine is composed of a fan, a flow guide device, a separation screen, a vibration motor, etc. During operation, in order to improve the quality of sunflower seed shelling, it is often necessary to manually adjust the relevant parameters of the separation system. For example, when the skin content in sunflower kernels increases, the air intake of the fan needs to be adjusted in time; when the kernels contain undetached seeds exceeding the standard, the angle of the vibrating motor and the s...
