Problems solved by technology

[0003] However, when multiple cameras are used to simultaneously shoot the same scene, it is often necessary to adjust the shooting parameters of multiple cameras separately, which cannot maintain the consistency of the shooting parameters
And when shooting synchronously, if the system time of each camera is different, it is prone to asynchronous shooting
[0004] It can be seen that due to the inability to maintain the consistency of shooting parameters and the occurrence of asynchronous shooting, there are problems of inconsistent pictures and affecting the effect of synchronous shooting

Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] The core idea of ​​the embodiment of the present invention is to uniformly adjust the shooting parameters of each camera in the camera matrix to the target shooting parameters, which can shorten the shooting parameter adjustment time, maintain the consistency of the shooting parameters of the cameras to the greatest extent, and control the shooting parameters based on the synchronization signal. Each camera in the camera matrix shoots and acquires audio synchronously, which can ensure the synchronization of target information acquisition corresponding to different cameras, and then can ensure the synchronous shooting effect and the consistency of the picture.

[0065] refer to figure 1 , which shows a flow chart of the step...

Abstract

The embodiment of the invention provides an information acquisition method, device and system, and the method comprises the steps: adjusting the shooting parameters of at least two cameras contained in a camera matrix to be target shooting parameters according to a shooting parameter adjustment signal, and enabling at least two cameras to be arranged in a preset mode; controlling at least two cameras to synchronously acquire target information at the shooting moment according to the synchronization signal, wherein the target information comprises image information shot through the target shooting parameter and audio information collected at the shooting moment, and the synchronization signal is corresponding to at least one shooting moment; and for each shooting moment, synchronously acquiring the target information acquired by at least two cameras. According to the invention, the consistency of the shooting parameters of the camera can be maintained to the maximum extent, the shootingcontinuity can be ensured when the environment state changes, and the consistency of the synchronous shooting effect and the picture can be ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an information collection method, device and system. Background technique [0002] At present, in application scenarios such as panoramic shooting, free viewing from multiple angles, and screen playback, multiple cameras can be used to capture images from multiple angles synchronously, thereby satisfying the user's viewing experience. [0003] However, when multiple cameras are used to simultaneously shoot the same scene, it is often necessary to adjust the shooting parameters of the multiple cameras separately, which cannot maintain the consistency of the shooting parameters. And when shooting synchronously, if the system time of each camera is different, it is prone to asynchronous shooting. [0004] It can be seen that, due to the inability to maintain the consistency of shooting parameters and the occurrence of asynchronous shooting, there are problems of inconsist...
