Problems solved by technology

However, at present, the quality grading of Agaricus bisporus in China still mainly relies on manual work, and fatigue and emotional instability caused by long-term use of the eyes will cause fluctuations in grading errors, and manual grading has the disadvantages of heavy labor, low productivity, and The grading standards are difficult to unify and the grading accuracy is unstable. Therefore, the establishment of an intelligent selection and grading system for Agaricus bisporus has important practical significance for realizing its efficient production.
At present, the image-based intelligent grading system is widely used in fruits, but there is no report on the intelligent grading of Agaricus bisporus

Embodiment Construction

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0036] In the method for grading Agaricus bisporus based on image processing provided in this embodiment, the original image is acquired first, and the collection of image information of Agaricus bisporus is the basis of intelligent grading. In this field, an image acquisition system is generally used for image acquisition: Agaricus bisporus is transported on the conveyor belt in an orderly manner, and an industrial camera is used to capture images, and the images are transmitted to the background for processing. The image is processed in the background, and Agaricus bisporus is graded according to the processing results. Therefore, good image processing results are crucial to accurate classification. The i...

Abstract

The invention discloses an agaricus bisporus grading method based on image processing, and the method comprises the steps: carrying out the watershed algorithm processing for the first time through combining a basic global threshold segmentation method and a searching maximum entropy segmentation method, extracting the complete agaricus bisporus through segmentation, and effectively removing a shadow caused by the non-uniform illumination; carrying out the watershed algorithm processing for the second time through the Canny operator, removing the interference from petiole, extracting the complete outline of the pileus of the agaricus bisporus, calculating the maximum diameter of the agaricus bisporus, and carrying out the grading of the agaricus bisporus. The method avoids the impact on the maximum diameter from the shadow generated during image collection and the pileus of the agaricus bisporus, obtains a good image processing effect, and improves the grading accuracy of the agaricus bisporus.

Description

technical field [0001] The invention relates to a method for grading Agaricus bisporus, in particular to a method for grading Agaricus bisporus based on image processing. Background technique [0002] Agaricus bisporus, also known as Tricholoma bisporus, white mushroom, sea mushroom, etc., has become the most widely cultivated and produced edible fungus variety in the world because of its white color, delicious taste, and thick texture. At present, Agaricus bisporus has achieved factory production, and the daily output of larger factories can reach hundreds of tons. However, at present, the quality grading of Agaricus bisporus in China still mainly relies on manual work, and fatigue and emotional instability caused by long-term use of the eyes will cause fluctuations in grading errors, and manual grading has the disadvantages of heavy labor, low productivity, and The grading standards are difficult to unify and the grading accuracy is unstable. Therefore, the establishment ...
