Panoramic imaging method based on camera array

Abstract

The invention discloses a panoramic imaging method based on a camera array and mainly aims to solve the problems that in the prior art, a splicing scene is small, and a "ghost shadow" exists. According to the scheme, (1) array cameras are used to acquire multiple images, two images are read, SIFT features of the two images are extracted respectively, feature matching search is performed, matching points of the two images are obtained and screened, an optimal transformation matrix is calculated, the images are transformed according to the optimal transformation matrix, and an improved optimal stitching line algorithm and a weighted average fusion algorithm are adopted to perform fusion splicing on the images; and (2) the step (1) is repeated till splicing of the upper image and the lower image is completed, the splicing image is used as a to-be-spliced image, splicing is continued after the to-be-spliced image is rotated counterclockwise by 90 degrees, and the result is rotated clockwise by 90 degrees to obtain a final splicing panoramic image. Through the method, the "ghost shadow" phenomenon is remarkably eliminated, and the obtained panoramic image is large in view field, high in resolution, more approximate to a real panorama and capable of being used for splicing of larger scene images in the horizontal direction and the vertical direction.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a panoramic imaging method based on a camera array, which can be used for splicing larger scene images in horizontal and vertical directions. Background technique [0002] With the development of science and technology, digital imaging technology is gradually stepping up to a new level, and digital imaging equipment has also begun to be widely used in daily life. Using digital cameras, mobile phones and other equipment to take photos has become an indispensable part of people's daily life. At the same time, the limitation of single camera imaging is also becoming increasingly apparent: in some special application scenarios, due to the limitations of digital imaging equipment itself, the needs of users cannot be well met. For example, when people want to obtain wide-field and high-resolution images, they can only use wide-angle cameras in many cases, but their...

Problems solved by technology

The disadvantage of this method is that only one direction of image can be obtained by taking a photo, and the final result cannot meet the needs of some large scene stitching
