Abstract

An embodiment of the present application provides an image mosaic method that acquires a first fisheye image and a second fisheye image collected by a fisheye camera and constructs a logical sphere according to a radius parameter of an imaging model of the fisheye camera, wherein the first fisheye image and the second fisheye image are respectively acquired by a first fisheye lens and a second fisheye lens whose optical axes are located on the same straight line and arranged opposite to each other in the fisheye camera. A projection mapping relationship between each of the first fish eye imageand the second fish eye image and the imaging model is determined. The first fisheye image and the second fisheye image are inversely mapped to the logical sphere based on the projection mapping relationship between the first fisheye image and the imaging model and the projection mapping relationship between the second fisheye image and the imaging model to obtain a spherical mosaic image. The spherical mosaic image is subjected to spherical expansion processing to obtain a 360-degree panoramic image. The invention can be applied to panoramic image mosaic of any image content.

Description

technical field [0001] The embodiments of the present application relate to the field of image processing, and in particular, to an image stitching method and electronic equipment. Background technique [0002] At present, image stitching technology is mainly used to stitch a plurality of images of different viewing angles into a 360-degree panoramic image. The imaging angle of view of the fisheye camera is greater than or equal to 180 degrees, and at least two fisheye images need to be spliced ​​to obtain a 360-degree panoramic image. [0003] However, the fisheye image collected by the fisheye camera usually has distortion. Generally, the fisheye image distortion is mainly divided into two types: one is the distortion caused by the lens of the camera itself and the process; the other is the distortion caused by the shooting angle. Because when using a single fisheye camera to shoot fisheye images, it is impossible to guarantee that each fisheye image has the same viewing ...
