Video synchronization method and system for multi-camera devices

Abstract

The invention provides a video synchronization method for multiple camera devices. The video synchronization method comprises the following steps that clock synchronization is carried out by a video frame time marking module and a video frame synchronization regulation module; the video frame synchronization regulation module outputs a driving signal to all the camera devices, wherein the driving signal controls the sampling frequency, on video signals, of the camera devices, and the driving signal output to all the camera devices is a driving signal which is subjected to clock synchronization; the video frame time marking module receives video signals collected by the camera devices, and time marks are added to each frame of image in the video signals; the video frame synchronization regulation module judges whether the video signals of the camera devices are synchronous or not according to the time marks, and if not, the sampling frequency, on the video signals, of the camera devices is adjusted through the driving signal. The invention further provides a video synchronization system for the multiple camera devices, wherein synchronization can be conducted on the video signals of the camera devices in real time, the processing process is simple and fast, and signal blockage caused by accumulation of asynchronous video data can be eliminated.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video synchronization method for multiple camera devices and a video synchronization system for multiple camera devices. Background technique [0002] Video information plays an important role in the expression of information in daily life, especially with the development of network technology, video technology is more and more involved in various neighborhoods of our lives, such as video conferences, video calls, monitoring, etc. Wait. Since ordinary cameras cannot capture multi-directional images, the visual range of watching videos is limited. [0003] For a long time, the acquisition of image information mainly comes from the capture of a single camera and the virtual generation technology of graphics and images based on graphics. However, with the development of image acquisition-related disciplines and the promotion of new technology requirements, the tradition...

Problems solved by technology

[0005] When the traditional software is used to splice multiple channels of video, the system lacks an adjustment mechanism, resulting in the accumulation of asynchronous image signals. This image accumulation leads to a delay in real-time image signals, which ultimately affects the performance of the entire system.

Using hardware to generate external trigger signals to achieve synchronization cannot ensure the synchronization of each frame of images; these synchronization methods of traditional technologies cannot ensure that the multi-camera panoramic acquisition system can simultaneously acquire the required image signals to meet the system splicing processing results the accuracy of
