A system and method for automatically selecting optimal images in bullet time

Abstract

A system and method for automatically selecting optimal images for bullet time, the system includes a pan-tilt camera group, a server and a controller; the pan-tilt camera group includes a plurality of cameras, and all cameras are evenly and spaced to be fixed for bullet time on the ring bracket, and the cameras of all cameras are facing the designated position in the middle of the ring bracket; the server is configured between the controller and at least one pan-tilt camera group installed on the same ring bracket through a communication connection, so that each camera can be controlled by the server Control and adjust; the optimal image automatic selection module is provided in the controller, which is used to automatically select the optimal image of each camera in the motion sequence captured by the optimal image selection algorithm, and the present invention simplifies the The production complexity of the bullet time visual effects saves the tedious process of manually selecting the optimal image for the user, and saves the manpower and time cost of the bullet time production.

Description

technical field [0001] The invention relates to a photographing device, in particular to a system and method for automatically selecting an optimal image in bullet time. Background technique [0002] "Bullet time", also known as "time cutting" or "time freezing", is a computer-aided photography technique used in movies, TV commercials or computer games to simulate variable speed effects, such as enhanced slow motion , time stop and other effects. Bullet time is well-known in the world for the scene where the hero avoids bullets in the movie "The Matrix" produced by Warner Bros. Pictures in Hollywood. [0003] Bullet time has five shooting modes: camera array, single camera shooting, scene still, CG animation, and multi-camera repeated shooting. Bullet time was originally achieved with a series of still cameras orbiting the object. These camera arrays are typically shuttered simultaneously or sequentially. Combining each frame of photos taken by each camera can form a vis...

Problems solved by technology

[0004] However, when shooting moving objects with bullet time special effects, users need to manually select the optimal image in the motion sequence for the production of bullet time special effects, which takes a lot of time and effort
