Video decoding method and device suitable for commanding and dispatching

Abstract

The invention relates to the technical field of video decoding, in particular to a video decoding method and device suitable for commanding and dispatching. The method comprises the steps of building a video monitoring system, acquiring a monitoring video, decoding the monitoring video, playing and displaying the monitoring video in real time, loading an artificial intelligence technology to assist a commander in scheduling decision making and the like. According to the design of the invention, all processor cores can be kept in a use state, and the video decoding efficiency is improved; the picture continuity can be better ensured, the transmission frequency band is saved, and certain image quality is ensured; video images with uniform pixels and picture sizes can be output, so that a large display screen is tidy and clear, damage of disordered video pictures to eyes of supervisors is reduced, abnormal conditions of a monitoring area can be found more quickly, commanding and dispatching can be carried out in time, and the monitoring and commanding and dispatching effects are improved; and the device can improve the video decoding efficiency, reduce the data loss in the video transmission process, and improve the video quality.

Description

technical field [0001] The present invention relates to the technical field of video decoding, in particular to a video decoding method and device suitable for command and dispatch. Background technique [0002] In recent years, more and more major incidents have exposed many problems in emergency management, which has caused many traditional working models and information processing methods to gradually fail to meet the development requirements of modern society. If the Internet and integrated communications can be used to build intelligent The command and dispatch center platform can help realize unlimited communication and real-time command and dispatch among various departments in society. The most basic condition to support the realization of real-time command and dispatch is a real-time video surveillance system. However, during the transmission of remote video, it will be affected by many factors and prone to data loss. In order to reduce data loss, the conventional ...

Problems solved by technology

However, in order to improve the efficiency of video decoding, multi-core processors are used to perform parallel decoding operations on multiple video frames. Traditional parallel decoding methods include frame-level parallel and macroblock parallel methods. When all frame-level parallel decoding is used, if the frames that can be processed in parallel When the number of cores is less than the number of cores of the processor, there will be a situation where the processor is idle, and when all macroblocks are decoded in parallel, it cannot be implemented in parallel, resulting in low decoding efficiency; at the same time, the conventional video code decoder performs video decoding Usually only record the error codes in the parsing process without doing any processing on the error codes, which will easily cause the subsequent modules to only output the correct codes, so that part of the display screen will be reduced after the video signal is displayed, seriously affecting the continuity of the screen. In addition, the command center often displays multiple monitoring images on the large screen at the same time, and the video images captured and uploaded by different camera devices inevitably have inconsistent pixels and image sizes, which may easily lead to confusion in the images displayed on the large screen , not clear, not only damage the eyes of the supervisors, but also seriously affect the monitoring effect, resulting in a decrease in the efficiency of command and dispatch
