Video Shake Correction Method and Device

Abstract

The invention discloses a video dithering correction method and device. The method includes the steps of determining a current frame image of a preset time point in a video and at least one angular speed in gyroscope data, determining at least one deflection angle by which the current frame image rotates around a corresponding coordinate axis in a preset 3D coordinate system and relative to a preset equilibrium position according to the angular speed, obtaining a correction coefficient when a first deflection angle which meets a preset condition exists in the obtained deflection angles, determining the deflection placement of the current frame image in the direction of the corresponding coordinate axis in the 3D coordinate system according to the first deflection angle and the correction coefficient, correcting the spatial position of the current frame image in the 3D coordinate system according to the first deflection angle and the deflection displacement, and projecting the current frame image with the corrected spatial position onto a preset 2D coordinate system to form the corrected current frame image which can be displayed. Through the scheme, video dithering caused by the unstable position of an electronic device in the video shooting process is reduced.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a video shake correction method and device. Background technique [0002] With the rapid development of science and technology, various electronic devices are continuously enriched and facilitate the life of the public. Due to the advantages of using electronic devices to process information conveniently, quickly, and saving resources, smart terminals have become an indispensable part of people's lives or work. [0003] Among them, smart phones, tablet computers and other electronic devices with cameras enable users to shoot videos they want at any time, which undoubtedly increases the user experience. However, during the video shooting process, due to environmental factors or other factors (walking, driving, etc.), the position of the electronic device cannot be kept stable when the user holds the electronic device, resulting in shaking of the captured video image, thereby reduc...
