Abstract

The invention brings forward a panorama image generation method and apparatus for a user terminal. The panorama image generation method for the user terminal comprises the following steps: obtaining multiple images shot by the user terminal, determining adjacent relations among the multiple images, and performing characteristic matching on adjacent images to obtain a matched characteristic point pair; according to the matched characteristic point pair and initial camera parameters, obtaining camera parameters after optimization; carrying out color adjustment on the adjacent images to obtain the adjacent images after the color adjustment; and according to the camera parameters after the optimization, splicing the adjacent images after the color adjustment so as to generate a panorama graph. The method provided by the invention can improve the image splicing speed.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a panoramic image generation method and device for a user terminal. Background technique [0002] Panoramas can be obtained through wide-angle shooting, but limited by the shooting hardware, more panoramas are obtained by splicing multiple images to show the surrounding environment as much as possible. In the prior art, the following methods are usually used to splicing multiple images to obtain a panoramic image: one is a general splicing method, which uses scale-invariant feature transform (SIFT) features and bundle adjustment ( bundle adjustment) to optimize image stitching, and the other is a stitching method for mobile phones, which can be divided into using the built-in sensor of the mobile phone to record the running track of the mobile phone to accelerate image stitching, and by performing color and light compensation on overlapping areas to improve stitc...
