As the resolution of high-definition video continues to increase, it will provide more and more clear data to further promote the development of intelligent skills. Together, the continuous development of intelligent skills will also promote the further development of high-definition video, transparent display for the promotion of high-definition video surveillance system to provide strong support.
In the process of using the high-speed rail video surveillance system, users’ requirements for image resolution are also increasing, and the demand for high-definition video is also increasing. The overall needs are divided into two categories, one for safety-related use and the other for service-related use. In safety-related use, the relevant railway departments have paid special attention to the tracking of wanted criminals in passenger stations, the prevention of criminal cases in the station and the activities of the Yellow Cattle Party. For example, some criminal cases in the passenger station require video recordings to view the physical characteristics of the suspects, but some of the imitation cameras currently deployed cannot provide useful image details. In addition, there are some key portal requirements videos that can be supplied to satisfy clear facial features, and existing imitation videos cannot do this in the context of a scenario.
In the service-related use, the most typical use is the ticket queuing control. The user hopes that the video can cover a large scene and then realize the dynamic monitoring of the number of ticket-purchasing passengers, so as to add a ticket sales window when people are intensive, and hope that the video can provide some details of the ticket seller and the passenger in the process of purchasing tickets, so that combined with voice is more convenient to handle some disputes. At present, the relevant departments of the Ministry of Railways have started the use of high-definition video experiments. At some passenger stations, the HD video products and skills of different manufacturers have been tested and verified. The experimental results are being further evaluated. In the newly released “Technical Conditions for Railway Integrated Video Surveillance System”, the definition and skill conditions of HD video have been clarified, laying a skill foundation for further use.
HD video surveillance uses problems with high-speed rail
The high-definition video surveillance system brings high-definition clarity together with a series of real-world problems. The reason is that although the front-end camera equipment can meet high-definition, the front-end “HD” does not represent the HD of the entire video surveillance system. “Transparent display screens will have a greater impact on video encoding, transmission and storage systems due to the multiplication of front-end video information. Because the HD video surveillance system is a system solution, it can be represented by not a high-definition camera. Together, there will be demand growth and skill changes in the entire industry chain for accounting, transmission, exchange and storage. The real high-definition monitoring system should consider high-definition from the whole monitoring system, including front-end video source acquisition, video signal encoding compression, video signal transmission, video browsing, video file playback and other aspects to fully support high-definition monitoring.
