Problems solved by technology

Urban road cameras often do not automatically adjust the resolution of the camera according to the traffic conditions of road vehicles. High resolution not only consumes a lot of power but also takes up a lot of storage space. Although low resolution can solve the problems of high It is very important for many detection tasks and directly affects the accuracy of the model
On the other hand, the images captured by the camera in real time are usually presented separately, lacking an overall perspective

Embodiment 1

[0040] In order to realize the present invention, it is necessary to construct the city information model CIM and the internal relationship of the information exchange module.

[0041] CIM refers to the organic synthesis of three-dimensional urban space model and building information based on urban information data, mainly composed of urban GIS data and BIM data.

[0042] The information exchange module mainly includes the three-dimensional urban space model and urban information, and will update its model and information content in real time as the construction progress of the smart city continues.

[0043] This solution uses CIM technology, which can better realize real-time imaging of urban roads and vehicles. Based on three-dimensional urban spatial geographic information, CIM superimposes the BIM information of urban buildings, above-ground and underground facilities, and urban Internet of Things information to construct a three-dimensional digital space urban information...

Abstract

The invention discloses a smart city CIM video big data image quality control method based on vehicle perception. The method comprises the following steps: constructing a city information model of a three-dimensional digital space; acquiring a road image in real time; inputting a to-be-detected road image into the trained vehicle detection network; superposing the obtained vehicle wheel thermodynamic diagrams and inputting the superposed thermodynamic diagrams into a trained camera resolution grading network to obtain a camera resolution grade and carry out resolution adjustment; and integrating the acquired images and the detection result into the CIM, and visualizing the city information model in combination with the WebGIS technology. According to the invention, intelligent smart city image acquisition is realized, the accuracy and efficiency of vehicle detection and road traffic condition analysis are improved, the storage burden of the camera and the transmission burden of the system are reduced, and the model visualization result is richer.

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence, smart city, and CIM, in particular to a method for controlling the image quality of CIM video big data in a smart city based on vehicle perception. Background technique [0002] At present, the global information technology is developing at an accelerated rate, and the status of information technology in the national economy is becoming increasingly prominent. The construction of smart cities has important strategic significance for the overall improvement of a country's comprehensive competitiveness. [0003] The emergence of smart cities stems from the new generation of information technology represented by the Internet of Things, cloud computing, mobile Internet, and artificial intelligence and the open urban innovation ecology that is gradually bred under the environment of a knowledge society. Smart city emphasizes the use of a new generation of information technology and th...
