Abstract

The invention discloses a video jitter removing method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: acquiring a first video frame and a second video frame containing a target object, and determining a region position of the target object in the first video frame and the second video frame; wherein the first video frame is a video frame corresponding to the target object at the previous moment, and the second video frame is a video frame corresponding to the target object at the current moment; and correcting the degree-of-freedom pose estimation of the target object at the current moment according to the inter-frame offset, and performing rendering imaging on the target object according to the corrected degree-of-freedom pose estimation. According to the embodiment, online real-time video jitter removal is realized, the application scene of video jitter removal is expanded, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for deshaking video. Background technique [0002] With the advancement of VR and AR technology, virtual try-on technology is booming, and the function of transforming shopping guides is becoming more and more popular among the public. For example, virtual shoe testing technology can help users see the effect of shoes "wearing" on their feet through the combination of AR augmented reality technology and smartphone cameras. Drift, there is a jitter phenomenon between consecutive video frames, which greatly affects the user experience. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Most of the existing video de-jittering is realized by post-processing the video, which cannot realize online real-time de-jittering, single application scenarios, and ...
