Abnormal traffic information collecting method based on unmanned aerial vehicle

Abstract

The invention provides an abnormal traffic information collecting method based on an unmanned aerial vehicle. The method includes the steps that a camera capable of being remotely and dynamically adjusted is arranged on the unmanned aerial vehicle, the camera is controlled to be parallel to a road to acquire orthographic projections of running vehicles in a road section, and the vehicle density of the road section is acquired according to the orthographic projections of the running vehicles in the road section. According to the method, real-time road conditions are collected through the unmanned aerial vehicle, the coverage range is very wide, various data is collected, and a guarantee is provided for accurate judgment of an intelligent traffic system. By means of the method, traffic information of the road can be detected, and a traffic control system can carry out traffic state detection, traffic safety early warning, traffic control induction and the like according to real-time traffic conditions and the traffic flow shown in images; by combining data collecting, unmanned aerial vehicle dispatching and induction building, input cost is greatly reduced, a safety guarantee and traffic dispersion are provided for the vehicles at the target road section, and accidents are effectively avoided.

Description

Technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for collecting abnormal traffic information based on a drone. Background technique [0002] In the face of globalization and informatization development trends in the world today, traditional transportation technologies and methods 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 transportation and a revolution in transportation. Through the effective integration and application of advanced information technology, communication technology, control technology, sensing technology, computer technology and system integration technology, the interaction between people, vehicles and roads can be presented in a new way, so as to realize real-time , Accuracy, efficiency, safety and energy saving goals. [0003] At present...

Problems solved by technology

[0004] The current traffic information collection systems are mainly divided into three categories: magnetic frequency, wave frequency, and video. The most widely used is the ring-shaped ground induction coil in magnetic frequency technology. The current in the traffic detector jumps up and exceeds the specified threshold to trigger the recorder to realize the counting of vehicles. The loop coil detection system and video detection system are all fixed-point traffic flow detection systems with limited coverage and cannot fully respond to regional traffic operations. Therefore, a new abnormal traffic collection technology is urgently needed to fully reflect the traffic operation status in the target area
