Collybia albuminosa-based pileus size in-situ measurement method

Abstract

The invention provides a pileus size in-situ measurement method based on termitomyces albuminosus. The method comprises the following steps: acquiring a thallus image, carrying out binarization to obtain a binarized image, and carrying out edge detection on the binarized image to obtain a pileus edge contour with interference; obtaining a center coordinate point of the pileus edge contour with interference and calculating a center coordinate value, obtaining an Euclidean distance between each contour point and the center coordinate point according to the center coordinate point and the center coordinate value, and screening and removing the contour points of which the Euclidean distances do not accord with a preset value to obtain a primary pileus edge contour; and obtaining the initial circle center and a plurality of contour distances between the preselected pixel points and the edge contour of the primary pileus, screening the plurality of contour distances to obtain a target pixel point and a target contour distance, then carrying out fitting to obtain a fitted pileus, and obtaining a real pileus size according to the fitted pileus. And the pileus size of the black skin termitomyces albuminosus is calculated through the automatically acquired thallus image, so that the measurement workload is reduced, and the measurement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of size measurement of G. nigra, in particular to an in-situ measurement method of the cap size based on G. nigra. Background technique [0002] Oudemansiella raphanipies belongs to Basidiomycetes, Layers, Agaric, Trillidae. The meat is tender, delicious, and nutritious. At the same time, it also has the value of lowering blood pressure, inhibiting pylori, and repairing gastric mucosa. It is loved by consumers. It is imperative to develop new varieties with strong disease ability and good quality. [0003] The size of the cap is the key point that must be paid attention to in the production and breeding process of G. nigra In today's emphasis on factory cultivation, it is the precondition to accurately measure the caps of Gallatella nigra growing on the mushroom bed or to judge whether it is at the best harvest time and to use machines for picking. [0004] Since the cap of G. nigra is approximately circu...

Problems solved by technology

[0005] Based on this, the purpose of the present invention is to provide a kind of in-situ measurement method of the cap size based on Gallus pilosulae, which is used to solve the problem of relying on artificial naked eyes and vernier calipers to manually measure the cap in the prior art, resulting in a large workload and low efficiency. Low, and the measurement error is large, not suitable for large-scale use of technical problems
