TLDR
In this article, a device for calculating the area proportion of a disease spot of corn southern leaf blight in the leaf of a corn plant is presented. But the device is not suitable for the use in the field of agriculture.
Abstract
The invention provides a device for calculating area proportion of a disease spot of corn southern leaf blight. The device comprises an image acquisition unit, an image preprocessing unit, an image feature extraction unit and an area proportion calculating unit. The image acquisition unit is used for collecting corn leaf images; the image preprocessing unit is used for carrying out de-noising processing, image grayscale processing and image threshold segmentation processing on the corn leaf images in sequence to obtain disease spot leaf images; the image feature extraction unit is used for extracting local texture information and edge feature information on the disease spot leaf images; and the area proportion calculating unit is used for calculating the area proportion of the disease spot of corn southern leaf blight in the leaf of a corn plant. The device for calculating the area proportion of the disease spot of corn southern leaf blight can calculate the area proportion of the disease spot of the corn southern leaf blight in a quick, accurate and low-cost manner.
