Problems solved by technology

Even if the bandwidth of a single camera is halved, if the acquisition / storage thread is not exclusive, thread switching is triggered, resulting in interruption of acquisition. If the interruption time exceeds the number of frames contained in the camera's internal cache, frame loss will occur

Abstract

The invention provides a synchronous acquisition system of multi-channel cameras. The acquisition system comprises a processing module group, a camera shooting module group and a signal generator; the camera shooting module group comprises a plurality of cameras; the processing module group comprises a plurality of processing modules, and one of the processing modules is a main control processing module; the main control processing module is used for distributing data acquisition instructions to the processing modules according to control instructions; the processing modules are connected with the cameras and used for setting the shooting parameters of the cameras according to the data acquisition instructions and obtaining data of images shot by the cameras; the signal generator is connected with the cameras separately and used for controlling the cameras to synchronously start shooting or stop shooting.

Description

Technical field [0001] The invention relates to the field of image shooting and collection, in particular to a multi-channel camera synchronization collection system and method. Background technique [0002] In fields such as virtual reality video production, in order to obtain more complete visual information, it is usually necessary to collect multi-angle high-resolution images at the same time and collect them at a high frame rate. This puts forward three requirements for the image acquisition system: 1. It can control multiple cameras at the same time and expand horizontally; 2. It can support high acquisition bandwidth; 3. The exposure trigger between multiple cameras should be synchronized. There are two technical solutions in the prior art to deal with the above requirements, as follows: [0003] In the first prior art, the system mainly controls multiple cameras through a single machine, that is, multiple cameras are connected to a single host PCIe through protocols such a...
