Abstract

The embodiment of the invention provides a synchronization system and method for multi-channel video acquisition and an acquisition controller, and aims to solve the problem that multi-channel videosacquired at the same time cannot be effectively synchronized in the prior art. The multi-channel video acquisition synchronization system comprises a server and a plurality of video acquisition cards,each video acquisition card comprises an acquisition controller and a module, and each module comprises a lens and an image sensor; the server sends a time synchronization instruction to the acquisition controller of each video acquisition card, wherein the time synchronization instruction comprises time synchronization time; the acquisition controller of each video acquisition card sets local time according to the time synchronization time; and the acquisition controller of each video acquisition card sends a control signal to the image sensor in the video acquisition card according to the local time and the same predetermined acquisition period, and the image sensor acquires image data according to the control signal.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a synchronization system, method and acquisition controller for multi-channel video acquisition. Background technique [0002] Currently, in many application scenarios, multiple imaging devices need to be configured to acquire image data for the same scene. However, due to their respective differences, there may be clock errors among the multiple imaging devices, resulting in asynchronous image data collected by the multiple imaging devices. Therefore, it is necessary to perform synchronous processing on multiple image data acquired by multiple imaging devices for the same scene. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a multi-channel video acquisition synchronization system, method and acquisition controller to solve the problem in the prior art that synchronous processing of simultaneously acquired multi-channel vid...
