Quick binocular fisheye panoramic picture stitching method based on fixed stitching parameter

Abstract

The invention discloses a quick binocular fisheye panoramic picture stitching method based on a fixed stitching parameter. The method comprises the following steps that: (1) arranging a fisheye panoramic picture stitching parameter acquisition device; (2) obtaining stitching parameters, i.e. a rotation offset parameter and a zone overlapping parameter; and (3) through the rotation offset parameter and the zone overlapping parameter, generating a fisheye panoramic picture stitching LUT (Lookup Table), and utilizing the LUT to realize the position mapping of the two fisheye pictures to the stitched picture so as to realize the quick stitching of the two fisheye pictures. Through a simple hardware device, the rotation offset parameter and an overlap ratio are obtained to obtain the LUT of the stitched fisheye picture, and the position mapping of the fisheye pictures to the stitched picture can be realized so as to realize the quick binocular fisheye panoramic picture stitching. The method has the advantages of being simple in operation, good in stitching effect, easy in hardware implementation and high in speed.

Description

technical field [0001] The invention relates to the technical field of fisheye image processing, in particular to a fast binocular fisheye panoramic image stitching method based on fixed stitching parameters. Background technique [0002] Panoramic image, as a kind of real-scene picture that can provide users with a large field of vision observation, is widely used in many fields such as virtual tourism, augmented reality, engineering development, emergency rescue and disaster relief, and robot navigation. Wherein the panorama image generation based on image mosaic mainly includes the following three ways: (1) adopt multi-camera special equipment, such as Facebook Surround 360, GoPro Odyssey, Chinese utility model patent (application number 201220019086.9, application publication number CN202455444U), etc., but this Such equipment is expensive, and the general public often cannot afford it; (2) Collect multiple images and stitch them together by rotating a single lens, such ...
