The present application relates to a video anti-shake method and device, electronic equipment, and a computer-readable storage medium, which acquire a sequence of image frames within a preset time period from a video, and perform inter-frame alignment on the image frames in the sequence of image frames to obtain a preset Average global translation over time period. Obtain the rotation angle of the current image frame, perform video anti-shake processing on the current image frame according to the rotation angle of the current image frame and the average global translation amount, and generate the anti-shake processed current image frame. By inter-frame alignment of the image frames in the image frame sequence within the preset time period, the average global translation amount within the preset time period can be obtained, and the average global translation amount can accurately reflect the Pan jitter. Therefore, based on the average global translation amount plus the rotation angle of the current image frame, the current image frame is subjected to video anti-shake processing from these two dimensions, which can enhance the anti-shake effect of the captured video and improve the clarity of the captured video. Spend.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a video anti-shake method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the continuous development of computer technology, the emergence of various intelligent terminals with different functions makes people's life more and more diverse and convenient. Among them, smart terminals with cameras and the like enable people to take images or videos anytime and anywhere to record their lives. However, in the process of video shooting, due to the factors of the shooting equipment, the environment or the shooting object, for example, the shaking of the hand when holding the shooting device, the shaking of the vehicle during the driving shooting process, the shaking of the shooting object, etc. Jittering occurs, and in severe cases, the video may even be blurred. Therefore, there is an urgent need to solve th...
