Problems solved by technology

However, in some special lighting environments (single light source, low or high brightness) the color correction effect of polynomial regression method is poor, and in some cases that require high calculation speed, color correction effect and accuracy, conventional polynomial regression Law does not meet the requirements

Abstract

The embodiment of the invention belongs to the technical field of image processing. The invention relates to an image color real-time correction method, device and system, computer equipment and a storage medium, and the method comprises the steps: obtaining original data, carrying out data preprocessing, wherein the original data comprise original image data and standard color card data, and thestandard color card data at least comprise two pieces of gray color block data, calculating an RGB three-channel mean value of each color block included in the standard color card based on the original image data, fitting the RGB three-channel mean value of the gray color block to obtain a fitting parameter, correcting all color blocks of the standard color card by utilizing the fitting parameters, calculating correction parameters through a polynomial regression model, performing color real-time correction on the original image data based on the fitting parameters and the correction parameters, and then displaying the image data after color correction. According to the embodiment of the invention, the image color correction precision and speed can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image color real-time correction method, device, system, computer equipment and storage medium. Background technique [0002] Color is an important feature of objects, and color information is used in all walks of life and is closely related to our lives. However, in the images generated by mobile phones, cameras, surveillance video and other electronic devices, the color of objects will change greatly with different lighting, and the camera parameter settings will also affect the image color. Therefore, in order to adapt to the constancy of human color and make the image collected by the imaging device correctly reflect the real color of the object, it is necessary to correct the color of the image. [0003] At present, color correction can be roughly divided into two categories: device-based color correction and image-based color correction. The device-bas...
