Embodiment Construction

[0088] like figure 1 Shown, the present invention provides a kind of purple soil image segmentation extraction method based on Chebyshev's inequality H threshold, comprising steps

[0089] S1: Acquire the color image containing the purple soil area, and convert the color image containing the purple soil area into the image I of the HSI color space;

[0090] S2: Obtain an adaptive segmentation threshold, perform adaptive segmentation on the image I, and obtain a binary image II;

[0091] S3: Eliminate the isolated pixel area of ​​the binary image II to obtain the binary image III;

[0092] S4: Fill the holes in the binary image III to obtain the binary image IV;

[0093] S5: Calculating the Hadamard product of the binary image IV and the color image containing the purple soil area to obtain an image with only the purple soil area. Through the above method, considering that the soil area of ​​the purple soil color image has good aggregation characteristics in the H component ...

Abstract

The invention provides a purple soil image segmentation and extraction method based on a Chebyshev inequality H threshold value, comprising the steps of S1: converting a color image containing a purple soil region into an image I of an HSI color space; 2, performing adaptive segmentation on the image I to obtain a binary image II; S3, eliminating the isolated pixel region of the binary image II toobtain a binary image III; S4: filling a hole in the binary image III to obtain a binary image IV; S6, obtaining a Hadamard product of a binary image IV and a color image containing a purple soil region to obtain a purple soil image; considering that the soil region of the purple soil color image has good aggregation characteristics in the H component of the HSI color space, the invention adaptively obtains the H component segmentation threshold value, and quickly, accurately and completely segments the soil region of the image from the background region.

Description

technical field [0001] The invention relates to an image segmentation and extraction method, in particular to a purple soil image segmentation and extraction method based on Chebyshev inequality H threshold. Background technique [0002] Machine vision recognition of soil has important practical value in agricultural production. In agricultural production, identifying soil is very important. Due to the complexity of the soil classification system, only a few experts from scientific research institutes can accurately identify the soil. It is also very difficult for the agricultural technicians on the front line of production to completely and accurately identify the local soil. It is very difficult to identify soil types from different regions. An international common problem. The development of artificial intelligence technology has made it possible for machine vision to identify soil. [0003] Machine vision soil recognition is to recognize soil images with complex backg...
