Method for acquiring panorama image by using two fish-eye camera lenses

Abstract

The invention relates to the technical field of image communication, and particularly relates to a method for acquiring a panorama image by using two fish-eye camera lenses. The method comprises the following operation steps: (1) camera configuration: two fish-eye lenses with view angles of greater than 180 degrees are oppositely arranged on a camera, so that two ends of the view angles of the two fish-eye lenses are overlapped; (2) image acquisition: the camera is arranged in a panorama, and acquires a part of the panorama through one fish-eye lens to form a first image, and acquires the other part of the panorama through the other fish-eye lens to form a second image, and two ends of the first image and the second image are overlapped; (3) image processing: a processor of the camera splices the first image and the second image to form a 360-degree panorama image. According to the method provided by the invention, two images can be quickly obtained by the two fish-eye lenses, and combined into a panorama image, the operation is simple and convenient, and the combination effect is good.

[0002] With the research of panoramic image stitching technology, from ordinary images to panoramic images, the camera is fixed on the tripod and rotated around the vertical axis to shoot, while taking into account the stitching efficiency and stitching accuracy, but there is no more efficient and general algorithm. Find Relatively appropriate balance key points make image stitching meet user needs in terms of efficiency and accuracy

Moreover, the existing panorama acquisition equipment is large, not easy to carry, and the operation is complicated. It needs to record a 360° panorama in the horizontal or vertical direction by surrounding the camera. The number of shots is determined by the horizontal FOV of the lens, generally not less than 4

Moreover, the viewfinder range of the existing ordinary lens is limited, and it is difficult to fully capture the scenery on both sides of the camera into the image, resulting in the inability to connect the edges of the image, and the camera will be offset during the rotation process, which is also one of the reasons why the edges of the image cannot be completely blended. Factors, and there will be a long time difference between taking multiple pictures, resulting in the inability to fuse the pictures taken

However, after the image acquisition is completed, it needs to be manually synthesized, which is technically difficult and time-consuming, and it is impossible to realize instant preview
