Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0042] The flow chart of the intelligent recognition method for wheat powdery mildew spore pictures is as follows image 3 shown, including the following steps:

[0043] Step 1: Select different expert models so that the accuracy of intelligent recognition can adapt to different requirements.

[0044]In practical application, different experts have differences in the identification rate of spores, which need to be refined; according to the relative error rate between the total number of spores of wheat powdery mildew identified by experts and the total number of spores identified by machine intelligence, it is determined in sections of 5% to 30%8 The relative error rate of different experts (or intelligent recognition model, expert model), specifically 6.1%, 8.5%, 11.7%, 14.4%, 17.1%, 20.9%, 24.6%, 28.1%, users can use according to their own ...

Abstract

The invention relates to an intelligent blumeria graminis spore picture identification method. The method includes the steps of selecting different expert models to enable the intelligent identification accuracy to be capable of adapting to different requirements; pre-processing blumeria graminis spore pictures; dividing the blumeria graminis spore pictures; extracting the color, texture and shape features of the blumeria graminis spore pictures; conducting intelligent identification on the extracted features of the blumeria graminis spore pictures. By means of the intelligent blumeria graminis spore picture identification method, the blumeria graminis spore density in unit volume in air for a certain time can be rapidly calculated, and the basic conditions of blumeria graminis spore diseases are obtained. By means of the intelligent blumeria graminis spore picture identification method, automatic dividing of the blumeria graminis spore pictures is achieved, and the problem that an existing manual dividing method is low in efficiency is solved; automatic identification and automatic counting of the blumeria graminis spore pictures are achieved, and the problem that an existing manual (expert) identification method is low in efficiency and prone to making mistakes is solved; the intelligent blumeria graminis spore picture identification method can be suitable for the different manual (expert) using requirements and high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and relates to an intelligent identification method for spore pictures of wheat powdery mildew fungus, which realizes automatic identification and automatic counting of the spore pictures of wheat powdery mildew fungus through software. Background technique [0002] Powdery mildew is one of the main diseases of plant diseases. It mainly harms plant leaves, stems, petioles, buds and petals. Then the affected plants will appear chlorotic, withered, shrunken, and young leaves will be twisted, resulting in poor growth and deformity of plants. Bloom and bear fruit. Wheat powdery mildew is one of the main diseases of wheat, which is distributed all over the world except some tropical areas. Before 1900, it had been reported in European countries such as Britain, France, Ireland, Belgium, Denmark, Netherlands, Switzerland and Finland. Although the United States, Canada, and Mexico hav...
