Embodiment 1

[0044] Urban construction should seize the convenience of technology, relying on BIM and other information technology, exclusive to build cities CIM model, the integration of resources, identify the location, construction of smart city to explore a new path to enhance the level of city services and quality of service.

[0045] The new infrastructure development as the goal of the new era of urban construction, construction refers to 5G, artificial intelligence, industrial Internet of Things, represented by the new infrastructure, essentially digital information infrastructure.

[0046] To build relations within cities CIM information model and the information exchange module.

[0047] CIM refers to the city information data base, to build a three-dimensional model of urban space and building information organic synthesis, mainly in the GIS data with BIM data constitute the city.

[0048] Information exchange module mainly contains three-dimensional model of urban spaces and city i...

Abstract

The invention discloses a smart city CIM real-time imaging method with image semantic perception. The method includes: constructing a city information model in a three-dimensional digital space; labeling key points and identities of each vehicle in the image of the sample set, and training a vehicle key point detection encoder and decoder; inputting images collected by a camera in real time into vehicle key points In the detection encoder and decoder, get the heat map of the key points of the vehicle and the identity labeling map; judge whether the rectangular area of ​​the vehicle overlaps and perform affine transformation according to the judgment result; perform Poisson fusion on the top view image of the vehicle and the background image collected by the camera; The result of Poisson fusion of each road camera is image stitched to form a complete regional image, which is projected into the CIM to visualize various information of the CIM model. The real-time smart city road vehicle imaging is realized, which not only has good robustness and low calculation amount, but also has higher quality real-time imaging results and better visualization effect.

Description

Technical field [0001] The present invention relates to artificial intelligence, smart city, CIM technical field, particularly relates to an image having a smart city semantic perceived CIM real time imaging method. Background technique [0002] At present, the global information technology is accelerating the development trend of information technology in the national economy increasingly prominent, the construction of smart city has important strategic significance to improve the overall competitiveness of a country. [0003] Smart City produced from networking, cloud computing, mobile internet, artificial intelligence and open innovation eco-city for the next generation of information technology and knowledge of the social environment on behalf of progressively nurtured. Smart City emphasized that the use of a new generation of information technology, and various communication terminals, and realize the wisdom of urban management and operation. [0004] Currently in imaging ci...
