Panorama generating method and device

Abstract

The invention provides a panorama generating method and device. The method comprises the steps that at least two original two-dimensional images are acquired by a smart mobile device which rotatinglyphotographs a real scene through a fisheye lens, wherein the boundaries of adjacent original two-dimensional images overlap or intersect; the rotation matrix of the smart mobile device in a world coordinate system when each original two-dimensional image in at least two original two-dimensional images is photographed; according to the rotation matrix of the smart mobile device in the world coordinate system when each original two-dimensional image is photographed, the relative position between at least two original two-dimensional images is determined; and at least two original two-dimensionalimages are stitched into a panorama according to the relative position between at least two original two-dimensional images. According to the method provided by the invention, the panorama generatingefficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of panoramas, in particular to a method and device for generating panoramas. Background technique [0002] Panorama is a technology that shows the surrounding environment in an all-round way through images. In the process of generating a panorama, it is first necessary to collect several images of the surrounding environment from a fixed point in the real scene; then project these images into a unified panoramic coordinate space according to the corresponding projection transformation relationship; in this coordinate In space, these images are stitched together into a complete panorama. When playing a panorama, the image of any viewpoint can be obtained through inverse projection transformation, so as to realize the observation of any viewpoint of the surrounding scene. [0003] When stitching images, it is necessary to rely on the positional relationship between multiple images. In the prior art,...

Problems solved by technology

The extraction of feature points is very time-consuming, and in order to extract enough feature points, the overlapping area between adjacent images needs to be large enough (generally more than 30% of the overlapping area is required), which often results in a large number of captured images. Two factors lead to the inefficiency and time-consuming of existing technologies in generating panoramas
