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 present application belongs to the technical field of image processing, and relates to a real-time image color correction method, device, system, computer equipment, and storage medium. The method includes: acquiring raw data and performing data preprocessing, and the raw data includes raw image data and Standard color card data, the standard color card data includes at least two gray color block data; Calculate the RGB three-channel mean value of each color block included in the standard color card based on the original image data, and the gray color block Fitting the average value of the three channels of RGB to obtain fitting parameters; using the fitting parameters to correct all the color blocks of the standard color card, and calculating the correction parameters through the polynomial regression model; based on the fitting parameters and correction The parameter performs real-time color correction on the original image data, and then displays the color-corrected image data. The embodiments of the present application can improve the accuracy and speed of image color correction.

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...
