Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0052] The bullet time special effect is to combine a series of still pictures into a video through post-processing software. When the video is played, the picture will shake. This phenomenon can be slowed down by increasing the number of cameras or strictly arranging the camera positions in the early stage of shooting. However, the shake of the video image cannot be completely eliminated through hardware design, and the ...

Abstract

The invention discloses a video image anti-shake method and system for bullet time shooting, wherein the method comprises the following steps: acquiring a camera sequence pose for shooting a to-be-processed image; according to the camera sequence pose, calculating the offset vector of the ideal positions of all cameras and an ideal position of a reference camera; calculating the position of a reference object which is jointly shot by all the cameras; according to the deviation vector of the ideal position of the camera and the position of the reference object, calculating the rotation matrix of the to-be-processed image and rotating the to-be-processed image, and splicing into a video, so that the problem of image shaking of the shot video in the bullet time is solved. According to the video image anti-shake method and system for bullet time shooting provide a fast and practical solution for bullet time shooting; and the method and the system are easy to operate, easy to master and good in video debouncing effect.

Description

technical field [0001] The present invention relates to the technical fields of video shooting and image processing, in particular to a video image stabilization method and system for bullet time shooting. Background technique [0002] "Bullet Time" is the result of taking a series of still photos at the same time through multiple camera arrays and merging them into a video. In the 1999 movie "The Matrix", the male protagonist dodges bullets, which is the application of this technique - hence the name "bullet time". It provides rich visual effects for scenes such as film and television, stages, weddings, events, etc., and can provide more realistic materials for applications such as games, 3D modeling, and AR. [0003] The bullet time special effect is to combine a series of still pictures into a video through post-processing software. When the video is played, the picture will shake. This phenomenon can be slowed down by increasing the number of cameras or strictly arrangi...
