Embodiment Construction

[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0074] A fisheye lens is a lens with a focal length of 16mm or less and a viewing angle close to or equal to 180°. The double fisheye lens has two lenses, and the two lenses are symmetrical front and back. Usually, two fisheye images can be captured at one time. Theoretically Only two fisheye images on the Internet can be spliced ​​to obtain the scene information around the double fisheye lens. But at the same time, because the fisheye ima...

Abstract

The invention discloses a panoramic image obtaining method and apparatus. The method comprises the steps of performing shooting by utilizing double fisheye lenses to obtain two fisheye images, wherein the double fisheyes lenses are two lenses arranged oppositely, and a sum of view field angles of the two lenses is greater than or equal to 360 degrees; mapping the two fisheye images to respective spherical models from a planar coordinate system; extracting feature points from the fisheye images subjected to the mapping, and performing matching on the extracted feature points to obtain feature point matching pairs; determining a transformation matrix between the two fisheye images subjected to the mapping by utilizing the feature point matching pairs; transforming the two fisheye images subjected to the mapping to be in the same spherical model by utilizing the transformation matrix; and splicing the two fisheye images in the same spherical model to obtain a spliced spherical panoramic image. The method and the apparatus are used for improving the splicing precision of the fisheye panoramic image.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for acquiring panoramic images. Background technique [0002] Fisheye lens is an ultra-wide-angle lens that simulates the effect of underwater fish looking up at the water surface. Its typical field of view is 180°, and some exceed 180°, greater than 220°, and even reach 270°. Fisheye lens has many advantages: it has a large viewing angle, can accommodate many scenes, and can adapt to shooting in a small space. Therefore, it is widely used in many computer vision fields such as virtual reality technology, robot navigation, and visual monitoring. [0003] Because the angle of view of the images captured by the fisheye lens is relatively large, only 2-3 images need to be shot by the fisheye lens to stitch together a 360° panoramic image. Therefore, in the production of panoramic content, such as panoramic virtual reality VR (Virtual Reality) video In pro...
