AI Technical Summary

Problems solved by technology

However, due to the large amount of road monitoring video data, the traffic information obtained from the fixed shooting angle of the monitoring video is limited. Only relying on the monitoring image data cannot effectively complete many complex monitoring tasks such as the temporal and spatial behavior analysis of video target objects and regional state monitoring.

Abstract

The present invention relates to the technical field of intelligent transportation, in particular to a traffic data visualization simulation method and system based on AI recognition, including: building a digital twin city based on a real city; obtaining road monitoring video corresponding to the digital twin city; Segment the monitoring video to obtain several frames of images, identify the vehicle information in each frame of images, and calculate the offset coordinates of the vehicle; store the vehicle information in the several frames of images in the data table, and record the occurrence of each vehicle The starting frame number at the time; traverse the data table according to the computer drawing time, read the vehicle information, and when traversing to the starting frame number, generate a simulated vehicle at the corresponding offset coordinates in the digital twin city scene. The invention is used to solve the technical problem that due to the large amount of road monitoring video data, it is impossible to effectively complete many complex monitoring tasks such as temporal and spatial behavior analysis of video target objects and regional state monitoring only relying on monitoring image data.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a method and system for visual simulation of traffic data based on AI recognition. Background technique [0002] In the process of urban construction and management, the road monitoring system plays an important role in the prevention and control of public security. The road monitoring points in the city are mainly distributed at road intersections and key road sections where traffic and people flow are relatively concentrated. Through image / video transmission channels Upload the road traffic conditions to the road monitoring and command center, and the personnel on duty at the center can keep abreast of the road conditions in each area in order to adjust the vehicle flow at each intersection and ensure smooth traffic. Or for monitoring violations of road vehicles, it can timely discover and arrange to deal with road traffic accidents, etc., and provide...
