AR video surveillance

(1) Functional Application

Establish an AR three-dimensional prevention and control system for hydrological stations, utilizing augmented reality technology to structurally describe the background information in videos, making the background information searchable and locatable, and achieving functions such as Beidou coordinate mapping, direction sensing, and video linkage.

(2) Operating Mode

The monitoring front-end equipment consists of cameras, poles, equipment boxes, etc. A set of panoramic AR eagle-eye cameras is arranged near the hydrological station to the highest point, achieving panoramic AR monitoring of the hydrological station. A set of network hard disk video recorders is arranged on-site for local video storage.

In terms of transmission, the monitoring images are transmitted to the monitoring center via optical fibers, and then transmitted in real-time to other relevant departments through the network. The video images are first stored in the local network video recorders and uploaded to the host computer for storage at a set time, in order to reduce the occupation of network bandwidth.

(3) Configuration Components

AR eagle-eye cameras, equipment poles, equipment brackets, hard disk video recorders, power supply equipment, communication equipment, equipment boxes, etc.

(4) Configuration Details

Seven stations (six basin demonstration stations + Xinshao station) need to be equipped with one set of AR video monitoring equipment each.
