Embodiment Construction

[0017] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0018] The term "server" in this context refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, which may include a processor and a memory, and the processor executes in the memory The pre-stored program instructio...

Abstract

The present application relates to a wide viewing angle live broadcast device for an event, which includes a wide viewing angle camera unit for acquiring a wide viewing angle image; an executable computer instruction sequence stored in a memory; to achieve: obtaining the internal parameter matrix and the distortion coefficient matrix of the camera unit ; performing pre-processing on the wide-angle image; performing expansion processing on the pre-processed image based on the internal parameter matrix and the distortion coefficient matrix to generate an expanded wide-angle image; generating an expanded image based on the expanded wide-angle image Wide viewing angle video stream; and transmitting the expanded wide viewing angle video stream to a streaming media server. The present application also relates to a related live broadcast system and method.

Description

technical field [0001] The present application relates to a live broadcast device and method, in particular to an event live broadcast device, system and method. Background technique [0002] The live broadcast of an event usually refers to the process of transmitting the image and sound of the event site to, for example, a TV, radio, computer, or mobile terminal in real time through a cable TV network, a broadcast network, or the Internet. With the development of Internet technology, Internet-based live broadcast technology has been greatly developed. For example, the emergence of streaming media technology can compress media data in segments and send data through the network, and transmit video and audio in real time on the network for viewing. Viewers use specific playback software to play and watch, and viewers can already use the playback software to basically enjoy the live video from the shooting angle of a certain video capture device in real time. [0003] When reb...
