Abstract

The invention discloses a video anti-shake method and system suitable for movable time-lapse photography and a shooting terminal.According to the method, key point extracting and key point matching are conducted on image frames of video to be processed, homography matrixes between the adjacent image frames are worked out according to the result of the feature point matching, a movement locus of the video to be processed is calculated according to the homography matrixes of the adjacent image frames, key frames in the image frames of the video to be processed are extracted according to the movement locus, and smoothing is conducted on the homography matrixes of the key frames so that stable video can be obtained.Only the video image information is utilized, frame extracting and smoothing are conducted by combining the relation between the image key point information and homography, the method is independent of hardware, the algorithm robustness is high, the anti-shake effect is remarkable, and the method is especially suitable for movable time-lapse photography with large shaking and is also suitable for anti-shake processing of ordinary video.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video anti-shake method suitable for mobile time-lapse photography and a system and a shooting terminal applying the method. Background technique [0002] Mobile time-lapse photography is a branch of time-lapse photography. It is a photography method that expresses rapid changes in shooting targets. It has a strong time compression ability and can compress long-term changes in things in a short period of time. Unlike traditional time-lapse photography that uses tripods and other equipment to fix the camera, during the shooting process of mobile time-lapse photography, cameras and other shooting equipment are mostly hand-held and follow the photographer. Due to the instability of handheld photography and the process of compressing video time, irregular high-frequency jitter of the photographic target will be caused. In order to improve the shooting effect of mobile tim...
