Abstract

The invention provides a consistency regulating method and system of a splicing panoramic picture, and belongs to the technical field of image processing. The method comprises the following steps of: firstly obtaining a mosaic diagram of an image to be spliced in a panoramic field of vision, wherein the mosaic diagram comprises a reference mosaic diagram; then creating a communicated channel between other mosaic diagrams and the reference mosaic diagram; calculating a gray stretch factor and an offset factor of other mosaic diagrams relative to the reference mosaic diagram; and regulating brightness of each pixel point of the corresponding mosaic diagram according to the obtained stretch factor and offset factor. Compared with the existing image brightness regulating method, the consistency regulating method is simple to realize, is especially suitable for brightness regulation of splicing monochromatic gray panoramic pictures with overlapped fields of vision and colors regulation of splicing panoramic pictures, is excellent in regulation effect, and can be used for solving the problems that uneven partial brightness / colors of a panoramic picture are caused by inconsistent overall brightness / color of all subpictures as a result of image-forming conditions in a panoramic picture splicing process.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a consistency adjustment method and system for mosaic panoramas. Background technique [0002] Panoramic image synthesis technology is widely used in virtual reality, medical image processing, remote sensing and telemetry image processing and other fields. [0003] Generally, when stitching images into a panorama, due to the influence of camera parameters, imaging conditions and other factors, there will often be differences between the overall brightness / color of some images to be stitched and the overall brightness / color of adjacent images in the field of view. There are obvious inconsistencies, so that there are obvious patch traces in the panorama obtained after synthesis, which affects the overall effect of the panorama. For example, at present, in the satellite panorama synthesized from images acquired by remote sensing satellites, such problems often ...
