Problems solved by technology

The panoramic stitching function is very practical and can greatly expand the expressive ability of the lens. However, in the existing panoramic image stitching, it is usually to find the corresponding points on the other image to be stitched according to the key points on one image, and then according to the key points The corresponding points directly align the images; however, since the images tend to be deformed during the shooting process, it is often encountered that the image to be matched is deformed relative to the original image. At this time, directly stitching the images to be matched will cause the image distortion crack

Embodiment Construction

[0057] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0058] An embodiment of the present disclosure provides a method for mosaicing panoramic images, which is used to improve the efficiency of mosaicing panoramic images and realize fast video search. Such as figure 1 As shown, the method includes steps S10-S30:

[0059] In step S10, multiple images for panorama stitching are acquired and stored in a database.

[0060] Wherein, the plurality of images used for panorama stitching may be photos taken continuously by the user with a shooting device with a built-in panoramic shooting function; it may also be a plurality of images individually stored in the database after the user shoots freely. The user can directly use ...

Abstract

The invention discloses a panoramic image stitching method and a panoramic image stitching device in order to improve the speed of stitching and the visual effect of image matching. The method comprises the following steps: acquiring multiple images for panoramic stitching and saving the images to a database; selecting a first image and a second image from the multiple images according to preset selection rules, and detecting whether the overlap area of the first image and the second image reaches a preset threshold; and when the overlap area of the first image and the second image reaches the preset threshold, deforming the second image, and stitching the second image and the first image. According to the scheme, after the second image to be stitched is deformed, the second image is stitched together with the first image set as the datum of deformation in a matching manner. Thus, the speed of stitching is improved, and the quality and visual effect of image matching are improved.

Description

technical field [0001] The present invention relates to the technical field of panoramic images, in particular to a method and device for stitching panoramic images. Background technique [0002] With the development of science and technology, the shooting of panoramic images has become a kind of daily shooting mode of current users, and many portable digital cameras and smart phones have built-in this function at present. The principle of panoramic image stitching is to stitch multiple consecutive photos into a panoramic photo. If you use a camera without panoramic stitching function to shoot, you can also use post-production software to make panoramic stitching photos yourself. The panoramic stitching function is very practical and can greatly expand the expressive ability of the lens. However, in the existing panoramic image stitching, it is usually to find the corresponding points on the other image to be stitched according to the key points on one image, and then accord...
