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 reali

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings and embodiments: figure 1 It is a schematic diagram of the principle of the present invention.

[0024] Such as figure 1 As shown, the method for collecting abnormal traffic information based on drones in this embodiment includes

[0025] A remote and dynamically adjustable camera device is installed on the drone, and the camera device is controlled to be parallel to the road and obtains the orthographic projection of the running vehicles on the road section, and obtains the road section vehicle density according to the orthographic projection of the running vehicles on the road section. In this embodiment, the cruise range (area) A of the drone is pre-delimited, and the length of the road section in the area is represented by L. A standard gallery is established, which includes the projection areas of different vehicle models and road pictures under normal operating conditions, and the ...

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...
