| Abstract |
At present, It is a pain point that there are much isolated and scattered video data of urban cameras, which cannot provide strong technical support for command and decision-making of managers. This paper studies the smart city scheme with high precision and high real-time display of video data, using video fusion technology to build a digital smart city. The platform architecture includes access layer, fusion rendering layer and presentation layer. The access layer provides access of sensors, cameras as well as models for data processing. The fusion rendering layer realizes the deep integration of multi-channel video into 3D models, which mainly involves camera calibration, image stitching, image projection and rendering optimization. Presentation layer is responsible for interface between a capability set and Web applications. The platform provides abilities of comprehensive and full-space awareness of security and response to emergency, and brings great economic and social benefits. It can be widely used in civil aviation, customs, ports, smart cities and other fields. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. |
