Method and device for image deshaking

Abstract

The present invention provides a method and device for image deshaking, wherein the method includes: acquiring two frames of binocular images, the binocular images including a left-eye image and a right-eye image; determining a plurality of common feature points, and determining the common feature points at The three-dimensional coordinates in two frames of binocular images; the common feature point whose moving distance is less than the preset distance value is regarded as a valid feature point, and the moving distance is the distance value between the two three-dimensional coordinates of the public feature point in two frames of binocular images ; Determine the pose change parameters of the camera according to the change values ​​of the three-dimensional coordinates of the effective feature points in the two frames of binocular images; adjust the coordinate values ​​of the pixels of the next frame of binocular images according to the pose change parameters. The image deshaking method and device provided by the present invention can conveniently and quickly determine the change of the camera pose, the method is simple, the algorithm complexity is low, the operation speed is fast, and the real-time performance is high, and the final determination of the change of the camera pose is more accurate.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image deshaking method and device. Background technique [0002] In today's society, cameras are widely used in various fields because of their simplicity and intuition. At the same time, due to the influence of factors such as application scenarios, application methods, and fixing methods, it is inevitable that the camera will shake the screen during video recording. This kind of image jitter will undoubtedly reduce the intuition and appreciation of the video, and even reduce the accuracy of later calculations based on video images. [0003] Currently, video image deshaking methods mainly include mechanical deshaking, optical deshaking and electronic deshaking. The method of mechanical deshaking is to install the camera on a mechanical structure with self-stabilizing function. Optical de-shaking is to sense the camera shake through the built-in instrument ...
