Problems solved by technology

These two types of detection methods cannot reflect the real-time status of abnormal traffic events, and cannot enable managers to clearly understand the traffic status and the severity of the event at that time, so that they can immediately take correct measures to solve traffic problems. Therefore, a new method is urgently needed. The abnormal traffic identification technology can combine the two to build a green and safe system

Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing and embodiment: figure 1 is a schematic flow chart of the present invention, figure 2 It is a schematic diagram of the principle of the present invention.

[0034] Such as figure 1 As shown, the UAV-based abnormal traffic identification method in this embodiment includes collecting traffic image information within the cruising range by the UAV and outputting it to the server, processing the traffic image information, and processing the processed traffic image information. The current traffic image information is compared with the preset normal state traffic image information to determine whether there is any abnormality in the current road section. In this embodiment, the aerial photography height h of the UAV is determined according to the road conditions and picture quality. When the flying height of the UAV is about 20m, the road conditions can be clearly seen. When the ...

Abstract

The invention relates to an unmanned aerial vehicle-based abnormal traffic identification method. The method includes the following steps that: an unmanned aerial vehicle acquires traffic image information in a cruise range and outputs the traffic image information to a server; the traffic image information is processed; current processed traffic image information is compared with preset normal state traffic image information; and whether a anomaly exists in a current road section can be judged. According to the unmanned aerial vehicle-based abnormal traffic identification method of the invention adopted; real-time traffic is photographed by the unmanned aerial vehicle, and pictures are automatically processed; picture information worthy of being distributed is selected and is uploaded to a traffic control system; based on a floating car method principle and an intensity projection method, the unmanned aerial vehicle is utilized to detect the volume of traffic of the road; and the traffic control system can perform operation such as traffic state detection, traffic safety early warning and traffic control induction according to traffic real-time condition and traffic flow in the pictures and perform picture receiving, processing and instruction distribution according to a cloud service platform.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a UAV-based abnormal traffic identification method. Background technique [0002] Facing the development trend of globalization and informatization in today's world, traditional transportation technology and means can no longer meet the requirements of economic and social development. Intelligent Transportation System (Intelligent Transportation System, referred to as ITS) is an inevitable choice for the development of the transportation industry, and it is a revolution in the transportation industry. Through the effective integration and application of advanced information technology, communication technology, control technology, sensor technology, computer technology and system synthesis technology, the interaction between people, vehicles and roads can be presented in a new way, thereby realizing real-time , Accurate, efficient, safe and energy-saving goals. [0003] At pr...
