Abstract

The invention discloses a 3D image generation method and device. The method comprises the steps of determining a matching point pair between two adjacent frames of images in a to-be-processed originalimage sequence based on the feature information of a first frame of image; based on the matching point coordinates corresponding to the matching point pairs between the two adjacent frames of images,determining the 2D affine parameters between the two adjacent frames of images; determining an accumulated 2D affine parameter and a smooth accumulated 2D affine parameter between a predetermined frame of image and the first frame of image in the to-be-processed original image sequence based on the 2D affine parameter between two adjacent frames of images; performing smooth mapping processing ofthe accumulated 2D affine parameters on the accumulated 2D affine parameters to obtain a target image sequence; generating a 3D image based on the target image sequence. According to the invention, the technical problem in the prior art that the shooting effect is influenced by shaking easily when a camera shoots around a certain target object, is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for generating a 3D image. Background technique [0002] At present, social sharing based on images and videos is mostly sharing of static image filters and special effects (AI or traditional image technology), short videos, and VR viewing of panoramic images. When the camera is centered on itself and shoots around, the panorama can be calculated based on panorama stitching technology, and can be processed into a VR browsing effect. However, when the photographer shoots around a certain target object, the video is prone to shaking, and the position of the target object on the image will change randomly, which will affect the shooting effect. [0003] Aiming at the problem in the above-mentioned related art that the camera tends to shake when shooting around a certain target object, no effective solution has been proposed yet.
