Description

technical field

[0001] The invention relates to the technical field of video acquisition and real-time video encoding and transmission, and is applicable to a real-time scene video acquisition system under high resolution requirements, in particular to an FPGA-based panoramic video acquisition and processing device. Background technique

[0002] With the general advancement of the 5G protocol, the era of the Internet of Everything has made it possible to realize live broadcast equipment with higher definition and larger data volume. Users' demand for video is advancing toward higher resolution, higher frame rate, and lower delay rate. Using high-speed interfaces and 5G interfaces, the high-resolution video acquisition system reduces the limitation of data transmission bandwidth and can bring users Brand new high-definition visual experience. However, the existing panoramic video stitching devices on the market are limited by the previous video transmission bandwidth, and of...
