Shooting synchronization method and shooting synchronization device

Abstract

The invention provides a shooting synchronization method used for performing synchronous shooting operations on a plurality of cameras by any camera in a multi-camera system. The shooting synchronization method comprises the steps of acquiring all cameras of current synchronous networks in a network broadcasting manner; acquiring signal transmission delays between the cameras; generating a synchronous shooting command for each camera according to the signal transmission delay of each camera; and sending the synchronous shooting commands to the corresponding cameras via a wireless network, thus achieving the frame synchronous shooting of all cameras in the multi-camera system. The invention also provides a shooting synchronization device. The shooting synchronization method and the shooting synchronization device provided by the invention are simple to install and convenient to operate, and the corresponding multi-camera system is low in production cost.

Description

technical field [0001] The invention relates to the field of multimedia content production, in particular to a shooting synchronization method and a synchronization device. Background technique [0002] With the development of science and technology, computer vision has been more widely used. In order to achieve better computer vision effects, it is necessary to use multiple cameras to capture images simultaneously when capturing images. For example, the currently popular panoramic cameras, VR cameras, and light field cameras with multi-camera systems all involve multi-camera collaboration, such as 3D modeling of objects captured by multiple cameras, sports and motion analysis by multi-angle shooting, or industrial robots. visual quality inspection system. [0003] The current common multi-camera synchronous shooting operation usually triggers image acquisition through the digital signal of the dedicated I / O port on the camera. With this setup, each camera must be connecte...
