Problems solved by technology
However, for the camera array directly formed based on the image sensor, the method of using the external synchronization of the cameras in the past has the following disadvantages: 1. The circuit for realizing the external synchronization between the cameras is relatively complicated; 2. The processor subsystem generally collects each video independently , the number of image frames is only based on the time of receiving data, and it is easy to lose synchronization in the processor, because the processor subsystem will be affected by processor interrupts or other processes when receiving image data

The invention provides a synchronous video acquisition process system of camera array, comprising: a video acquisition subsystem, a synchronous signal generation unit, a frame number generation unit, a processor subsystem used for receiving and processing the video signals, a synchronous signal input video acquisition subsystem and a frame number generation unit generated by the synchronous signal generation unit. The frame number generation unit generates frame numbers. Each video acquisition unit of the video acquisition subsystem receives the frame numbers and puts them into current frame image data. A data processor in the processor subsystem further obtains the frame numbers, which may directly input to the data process subsystem, from the received image data. The invention is capable of implementing synchronization of video images of multiple cameras in the camera array.
Description
technical field [0001] The invention relates to a camera array video acquisition and processing system, in particular to a camera array video frame synchronization processing system and a synchronization operation method thereof. Background technique [0002] With the development of video technology, 3D TV and related technologies have become a new development direction of video processing technology after digital TV. In the process of collecting 3D video signals, a camera array is usually used, and each camera in the array captures images simultaneously from multiple angles and viewpoints to provide richer information for 3D video. Therefore, the synchronization among the cameras in the camera array is particularly important. [0003] In the process of collecting 3D video signals, it is necessary to collect video signals from each camera at the same time. Therefore, it is very important to ensure the frame synchronization of simultaneously captured videos between cameras....
