Problems solved by technology

However, each sub-system of the virtual reality system is now synchronized internally, and the information collection and transmission between the systems are indeed asynchronous, which makes the space-time uncertainty in the data collection and reconstruction process of the virtual reality system, resulting in frame errors, jumps, and frustrations in the system. question
Since the motion capture and display cannot be synchronized in a timely and effective manner, in severe cases, it will cause dizziness or even vomiting to the experiencer.

Abstract

The present disclosure provides a multi-camera synchronous working method, medium and electronic equipment. The synchronous working method includes: when a graphics card frame synchronous refresh signal is detected, then determine to acquire at least one frame-synchronous broadcast data corresponding to the synchronization instruction A packet; sending frame-synchronized broadcast data packets to at least one camera in a broadcast manner, so as to synchronously trigger at least one camera to start image acquisition, and sequentially output image acquisition data of multiple cameras in a preset order. The multi-camera synchronous working method provided by this disclosure uses the frame synchronous refresh signal of the graphics card to synchronously trigger each camera to start the process of acquiring images, which can effectively ensure that each camera in the same system starts synchronously based on the frame synchronous signal output by the system display Image acquisition, multi-camera synchronous acquisition and data output are serially and orderly to avoid conflicts, to achieve the purpose of synchronous work of signal input and signal output, and to improve the reliability and accuracy of the synchronous work of the entire system.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, to a method, device, medium and electronic equipment for multi-camera synchronous work. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. Immerse yourself in that environment. [0003] The virtual reality system is composed of motion capture system, data processing and three-dimensional reconstruction system and display system. The virtual reality system is a real-time spatio-temporal processing system, and the complete synchronization of each subsystem in the system is required to ensure the real-time accuracy of data collection and reconstruction of the system. However, each sub-system of the virtual reality system is now synchronized internally, and the information collection and transmission between the systems are indeed asy...
