Embodiment Construction

[0052] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0053] figure 1 A schematic flow diagram showing a calculation method of a crop disease index provided by an embodiment of the present invention, as figure 1 As shown, the method includes the following steps:

[0054] 101. Acquire images of crops, and perform preprocessing on the images;

[0055] For example, the image may be an image acquired from an image acquisition device, and the crop may be a crop such as vegetables. When the image acquisition device acquires an image of the crop, the image includes images of leaves of the crop. This image can be understood as a color image.

[0056]102. Divide the preprocessed image into multiple sub-images, and extract color featu...

Abstract

The invention discloses a computing method and a computing method system for crop disease index. The computing method comprises the following steps: acquiring image of crop and pre-processing the image; dividing the pre-processed image into multiple sub-images and extracting color characters of the sub-images; using a minimum distance classifier for identifying the disease types and disease level of the sub-images according to the color characters of the sub-images; computing the crop disease index according to the disease types and disease level of the sub-images. The method solves that the disease index computing of the prior art depends on experience and knowledge of pathology of field crop protection persons, the statistical result is inaccurate and manual computation is required. The method is conducive to improve the prevention and treatment level for crop disease index and promote the implementation of precision agriculture, and novel method and technology are provided for the crop disease prevention and treatment field.

Description

technical field [0001] The invention relates to the field of crop disease prevention and control, in particular to a calculation method and system for crop disease index. Background technique [0002] With the development of the crop industry, the damage of crop diseases is becoming more and more serious. Since the diagnosis of diseases is basically analyzed and judged by experience and pathological knowledge, farmers lack the knowledge of scientific and rational use of pesticides in the process of crop production, resulting in the misuse and abuse of pesticides. If the automatic identification of crop diseases can be realized and the disease index can be accurately calculated, it will be possible to selectively apply pesticides according to the specific conditions of the diseases, reduce the "carpet" spraying of large areas of pesticides, and greatly reduce the use of pesticides Quantity, from the source to ensure the safety of crop production. [0003] The disease index ...
