Application of Perceptual Camera in Nanning's Safe City
From 2011 onwards, after two phases of construction, Kodak has assisted Nanning and established a preliminary framework for a safe city: more than 5,000 public security monitoring points and card points have been deployed; the municipal public security bureau has been established - the district/county branch office ——Three-level monitoring system at the local police station; completed the construction of basic systems such as video networking and bayonet networking within the public security video special network.
With the continuous expansion of the construction of safe cities in Nanning, the public security departments have gradually highlighted some problems in the actual application of image processing. The main issues are: 1 The monitoring and card point coverage is still insufficient; 2 The video images stored in the system have reached the PB level. Difficult to meet the needs of efficient storage management and rapid call, the difficulty of smooth expansion increases; 3 video clue retrieval, positioning, extraction rely mainly on the sea tactics, the efficiency is not high.
In response to the above problems, the third phase of the Nanning Safe City project was officially launched. After discussing with the public security department, we decided to apply cloud, perception, big data and other advanced technologies to improve the efficiency of Nanning’s safe city system from the front-end, platforms, storage, and applications. The main construction content of front-end-aware cameras is as follows:
2200 HD, 90% Perceptual Camera
In urban arterial roads, urban-rural junctions, major traffic junctions in rural areas, chaotic areas, border crossing areas, etc., 1,518 security monitoring points were built, and 2,200 high-definition monitoring front-ends were used, including bolts, domes, high-altitude observations, and infrared monitoring. Laser monitoring and so on.
In the newly built surveillance front-end, 90% is the Kodak-aware camera series. While taking HD monitoring into consideration, it can provide the best snapshot of the moving target in the scene and the semantic description of the main features such as target category, color, and direction of travel. In key areas such as key roads, government buildings, and other key areas, Kodak's Awareness-based Intelligent Tracking System is deployed - a bolt camera takes a panoramic view. The dome camera is responsible for tracking moving targets in close-up, presenting panoramic and tracking two-way video, and providing the most moving targets. Good snapshots and semantic descriptions of key features.
200 security checkpoints deploy 600 awareness cameras
In the city's entrances and exits, on the main roads, 200 HD security security card points were added, 600 Kodak-aware vehicle bayonet cameras were deployed to cover 600 lanes, and a panoramic surveillance camera was set up at each bay point.
The deployed Kodak-aware vehicle bayonet camera can capture and identify motor vehicles, non-motor vehicles, and pedestrians while providing 3 million pixels or more of pixel video images; the driver's face is clearly presented and the license plate number is recognized throughout the day. , color, model, car standard and other vehicle information.
On the basis of the construction of front-end-aware cameras, at the same time, the construction of the Kodak Cloud storage system can facilitate the expansion of 20,000 lines of business. It can not only store and manage 3000 new monitoring points in the third phase, but also integrate more than 5,000 monitoring points in Phase II and Phase II. Resources; Building a cloud computing big data platform that can support system management and scheduling for 10000-channel monitoring front-ends, quickly respond to a large number of service data services, and satisfy massive concurrent requests from business systems and users from various departments and regions, realizing intelligent video Large-scale deployment of monitoring systems.
With the arrival of perceptual cameras, cloud storage, and cloud computing platforms, the problems encountered in the practical application of safe cities in Nanning have been effectively solved, and this ancient city with a long history has been radiating wisdom. High-definition intelligent surveillance sites cover the streets and alleys; all video images, vehicle information, and personnel information related to safe cities are all stored and managed centrally; large-scale video surveillance services and video image analysis requirements are easily handled; intelligent image and video analysis The ability is more accurate and the false alarm rate is lower. The analysis and processing of various types of data are related to each other and collide with more clues... Let the data really be used, so as to provide overall public security work efficiency.
