Image processing method and device, readable storage medium and electronic equipment

Abstract

The invention discloses an image processing method and device, a readable storage medium and electronic equipment, and the method comprises the steps of obtaining an RGB image, and enabling a photographing object contained in the RGB image to be a test card; determining at least one connected region of the RGB image; for each connected region, determining a distance value set in the connected region to obtain a distance value set corresponding to the at least one connected region; and determining the chromatic aberration of the RGB image according to the distance value set corresponding to each of the at least one connected region, so as to correct the RGB image according to the chromatic aberration. By determining the distance value set of the connected regions in the RGB image and determining the chromatic aberration of the RGB image according to the distance value set, the purposes of quantifying the measurement of the chromatic aberration of the image, avoiding the subjective judgment of the chromatic aberration and improving the chromatic aberration measurement precision are achieved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, readable storage medium and electronic equipment. Background technique [0002] Chromatic Aberration (CA) is an optical phenomenon caused by the inability of the lens to focus all colors of light to the same converging point because the lens has different refractive indices for light of different wavelengths. Chromatic aberration can be divided into axial chromatic aberration (Axial Aberration or Longitudinal Aberration) and lateral chromatic aberration (Lateral Chromatic Aberration). In the prior art, adjusting lenses or replacing high-quality, expensive lenses is often used to eliminate chromatic aberration at the lens, and the high cost of such methods will limit the wide application of such methods or devices in cameras. In addition, those skilled in the art often judge the degree of chromatic aberration by the imaging qua...

In the prior art, adjusting lenses or replacing high-quality, expensive lenses is often used to eliminate chromatic aberration at the lens, and the cost of such methods is relatively high, which will limit the wide application of such methods or devices in cameras

In addition, those skilled in the art often judge the degree of chromatic aberration by the imaging quality of the edge of the image, and then adjust the lens to eliminate the chromatic aberration. The choice of
