Method and device for determining camera movement mode

Abstract

An embodiment of the present invention provides a method and device for determining a lens movement mode, wherein the method includes: determining a first feature point set from a current frame image of video data; determining a second feature point set from a comparison frame image of video data , comparing the frame image and the image of the frame image belonging to different frames; using the feature points matched by the first feature point set and the second feature point set as the associated feature point pair set; calculating the geometric transformation method of the associated feature point pair set; Determining the geometric transformation mode as the lens movement mode corresponding to the associated feature point pair set; determining one of the lens movement modes in the lens movement mode as the lens movement mode of the current frame image relative to the comparison frame image. This reduces the workload of the preliminary editor and improves work efficiency. Moreover, the camera movement mode of the current frame image relative to the comparison frame image is automatically determined, which saves labor cost and time cost.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a method and device for determining a camera movement mode. Background technique [0002] At present, during the recording process of video programs such as film and television dramas, a large number of video source materials will be generated due to factors such as different camera positions, different camera angles, and different scenes. The different scenes are due to the different distances between the camera lens and the subject, resulting in the difference in the range of the subject displayed in the camera viewfinder. status obtained. Generally, the lens movement mode in the video clips is classified through preliminary editing, so that the later editors can fine-tune the video clips that need to be fine-tuned. In this way, post-editing personnel can put together the video clips of the same scene’s camera movement mode and fine-tune it, so as to express different ...

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a method and device for determining the camera movement mode, which is used to solve the problem that the preliminary editor needs to browse hundreds of hours of video clips in the prior art, and then determine the camera movement of the video clips that need to be finely edited. method, heavy workload, low work efficiency, thus wasting a lot of technical problems of time cost and labor cost
