Embodiment Construction

[0058] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0059] In view of the brightness inconsistency in the mosaic area of ​​the panoramic image, the present disclosure proposes a brightness consistency adjustment algorithm, which adjusts the brightness of the original data of the camera before splicing, and improves the brightness consistency of the stitched image. In one embodiment, the method comprises the steps of:

[0060] S202: Acquire the first image to be stitched and the second image to be stitched, determine the first common area shared by the first image to be stitched and the second image to be stitched, and calcu...

Abstract

The invention provides a method for improving the brightness of a spliced image, and the method comprises the steps: determining a first common region shared by a first to-be-spliced image and a second to-be-spliced image, and respectively calculating the color mean values of the first to-be-spliced image and the second to-be-spliced image in the first common region, determining a target mean value of the first common region based on the two color mean values, and determining an adjustment parameter of the first common region according to the target mean value and the color mean values; determining a second common region shared by the second to-be-spliced image and the third to-be-spliced image, calculating color mean values of the second to-be-spliced image and the third to-be-spliced image in the second common region, and determining a target mean value of the second common region based on the two color mean values, determining an adjustment parameter of the second public area according to the target mean value and the color mean value; determining an adjustment parameter of a central region of the second to-be-spliced image according to the adjustment parameters of the two common regions; and respectively adjusting display images of the corresponding regions based on the adjustment parameters.

Description

technical field [0001] The present disclosure relates to the field of image processing, in particular to image processing used in a vehicle-mounted panoramic view system. Background technique [0002] In the car surround view algorithm, the internal and external parameters of the four cameras are obtained through calibration, and then the original images of the cameras are used to perform perspective transformation and projected to the ground, and then spliced ​​to obtain a panoramic image. Due to differences in imaging environments (shade occlusion, taillights on, etc.), lens differences, etc., there are brightness differences in the raw data of different cameras in the same scene, resulting in inconsistent brightness in the stitching area of ​​the panoramic image and poor display effect. Such as figure 1 As shown, the image brightness in each region is obviously inconsistent. Contents of the invention [0003] Therefore, it is necessary to provide a method, a device, a...
