Vision-based needle mushroom mature state detection method

Abstract

The invention discloses a vision-based needle mushroom mature state detection method, and relates to the field of mushroom growth detection. The problems that mushroom growth cannot be effectively detected, mushroom quality growth difference is caused, and the mushrooms are delivered out of a warehouse too early or too late are solved. The method specifically comprises the following steps; the method comprises the steps of S1, system initialization, S2, real-time image acquisition, S3, filtering, S4, image binarization processing, S5, contour extraction, S6, needle mushroom head recognition, S7, calculation of the contour sizes of all mushroom heads, S8, calculation of the proportion of the mushroom heads meeting the requirement in all the mushroom heads of a culture dish, and S9, detection completion and result output. According to the method, the overall size of the mushroom head is extracted, the size of the mushroom head is used as a ripening judgment condition of the needle mushroom, and comprehensive judgment of the ripening degree of the mushroom head in the same culture dish is used as a warehouse-out condition. The warehouse-out condition of the flammulina velutipes can be accurately judged, and the growth quality of the flammulina velutipes is improved.

Description

technical field [0001] The invention relates to a detection method for the maturity state of Flammulina velutipes based on vision, and belongs to the technical field of mushroom growth detection. Background technique [0002] The edible fungus industry is a sunrise industry emerging under the background of targeted poverty alleviation in recent years. The edible fungus industry mainly includes the cultivation, transfer and cultivation of strains. Flammulina velutipes is one of the most widely planted strains of edible fungi. After the cultivation is completed, the strains need to be sterilized at a high temperature of about 120 degrees and then enter the cultivation room for cultivation. The growth status of Flammulina velutipes during the cultivation process in the sterile room can only be judged by human eyes combined with time estimation, resulting in uneven growth quality of mushrooms, different sizes of mushroom heads, and even time errors will cause a certain amount o...

AI Technical Summary

Problems solved by technology

Flammulina velutipes is generally required to be incompletely mature in order to maintain the corresponding freshness, but it should not be too fresh, which will affect the output of Flammulina velutipes

The traditional method of enoki mushroom delivery is not strict in 28 days. The planting time, light and humidity of enoki mushrooms will all affect the growth of the mushrooms.
