Embodiment Construction

[0063]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0064] The first thing to explain is that the actual environment used by industrial smart cameras is changeable and complex. Some ambient light may be brighter, making the overall image brighter, and some ambient light may be darker, making the overall image darker. Dark and light images are processed separately. However, sometimes it is not enough to only consider whether the image is in a dark environment or a bright environment. There may be some interferenc...

Abstract

The invention relates to an image feature enhancement method and device for an industrial intelligent camera and a readable storage medium. The image feature enhancement method comprises the steps of receiving a to-be-processed original image and an exclusion factor input by a user; performing adaptive brightness processing on the original image to obtain a first intermediate image; performing gray interference removal processing on the first intermediate image according to the elimination factor, and determining a maximum gray value and a minimum gray value in the image after the gray interference removal processing; performing enhancement processing on the first intermediate image according to the maximum gray value, the minimum gray value and the acquired enhancement factor so as to acquire a second intermediate image; and performing reverse brightness processing on the second intermediate image to obtain a final image. By implementing the technical scheme of the invention, the contrast between the image gray levels can be enhanced on the basis of retaining the image information to the greatest extent.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to an image feature enhancement method, device and readable storage medium for industrial smart cameras. Background technique [0002] In the actual use of industrial smart cameras, it often encounters the problem that the image features are not strong due to the complex use environment, and due to the interference of some deviated gray values ​​in the image, it will affect the result of enhancing image features , so the enhancement effect is not good. At present, some methods are to enhance image features by enhancing image contrast, such as gamma transformation, histogram equalization, logarithmic transformation and exponential transformation, etc. These methods have certain effects, but in actual use, the choice of gamma value of gamma transformation It is a difficult point, a gamma value is difficult to enhance all types of image features; using histogram equalization often causes...
