Embodiment Construction

[0038] All the features disclosed in this specification, except mutually exclusive features and / or steps, can be combined in any way.

[0039] Combine below Figure 1 ~ Figure 2 The present invention will be described in detail.

[0040] A panorama mosaic color correction method, comprising the following steps:

[0041] Step (S1), determine the position of the overlapping area 3 of two original images (selecting one as the target image 2 and the other as the deviation image 1);

[0042] Step (S2), screening the pixels in the overlapping area 3;

[0043] Step (S3), using the filtered pixels to calculate the color difference between the two original images in the overlapping area 3 for imaging the same object in the actual scene, and obtain a fixed color difference, and then obtain two by mathematical fitting calculation The color deviation conversion parameter M of the original image;

[0044] Step (S4), using the color deviation conversion parameter M to perform color conv...

Abstract

The invention discloses a panorama mosaic color correction method, comprising the following steps: step (S1), determining the position of the overlapping area of ​​two original images; step (S2), screening the pixels in the overlapping area; step (S3), Calculate and obtain the color deviation conversion parameter M of the same object in the actual scene in the overlapping area of ​​the two original images by using the filtered pixels; step (S4), use the color deviation conversion parameter M to perform color conversion on the two original images. The invention solves the technical problem in the prior art that there is still color deviation after processing the seams of image splicing, and ensures that the final image will not produce obvious traces of color difference during panorama splicing.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a color correction method in panoramic video stitching. Background technique [0002] At present, in the field of panoramic video shooting, one camera is used with 2 to 6 lenses, or multiple cameras, or one camera is shot multiple times to obtain images, and then the series of images are stitched together. Due to differences in the brightness of different scenes, chromatic aberration in the lens, and differences in exposure, the brightness of different pictures cannot be guaranteed to be the same. The panoramic image obtained after using such image stitching will have obvious chromatic aberration. Generally, in order to eliminate the obvious "traces" at the stitching seam, a common practice is to slow down the difference between the two images by merging the overlapping stitching area, but only processing the stitching seam cannot Fundamentally change the co...
