Abstract

The invention relates to a pixel brightness calibration method and device for a panoramic image, a panoramic camera and a memory medium. The method comprises the steps of determining a brightness meanvalue change range of each overlapping area of the panoramic image; obtaining a brightness calibration reference value of the panoramic image according to the change ranges; obtaining a brightness mean value of each overlapping area of a current image; and calibrating brightness values of pixels of the current image based on the brightness mean values and the brightness calibration reference value. The brightness calibration reference value can reflect brightness difference of the overlapping areas of different lenses on the whole. The brightness calibration reference value is combined with the brightness mean values of the overlapping areas of to-be-calibrated images and the brightness values of the pixels of the images are calibrated, so integrated brightness change of the panoramic image is reduced. In a late phase of generating the panoramic image, the images are reprocessed, brightness level difference cannot be seen on the whole, the brightness of the image photographed by eachlens is effectively adjusted, imaging quality of the panoramic camera is improved, and panoramic photographing experience is also improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for correcting pixel brightness values ​​of panoramic images, a device for correcting pixel brightness values ​​of panoramic images, a panoramic camera and a computer-readable storage medium. Background technique [0002] When shooting images, a panoramic camera usually uses multiple lenses with different orientations to shoot, and stitches the images taken by each lens into a panoramic image of 360 degrees horizontally and 360 degrees vertically, wherein the number of lenses of the panoramic camera is generally greater than or equal to Two, during the use of the panoramic camera, due to the different orientations of each lens, the illuminance of each lens is very different, and the exposure difference between the images captured by each lens is also very large, resulting in the panoramic image generated by stitching. There will be a large difference bet...
