Abstract

The invention belongs to the technical field of traffic guidance, and discloses a method and system for air-ground combined rapid investigation of traffic accidents. The method comprises the steps: obtaining the alarm information of a traffic accident, and determining the position of the traffic accident according to the alarm information; enabling the unmanned aerial vehicle to fly to the scene according to the position information, taking a picture right above the traffic accident, and sending the picture of the traffic accident to a command center; fixing known parameters according to the road width of the road or the length of the vehicle, and endowing photo measurement information; setting and drawing a reference line on the photograph; identifying a traffic accident vehicle, and automatically generating positions of the vehicle and the reference line; and filling a fixed vehicle traffic accident symbol on the photograph; wherein the unmanned aerial vehicle carries the microphoneto give a shouting prompt while taking a picture to obtain picture information. According to the method, rescue route planning is carried out through the established model after the congestion interval is determined, the planned route is short, the consumed time is short, rescue is carried out in time, and the rescue effect is better.

Description

technical field [0001] The invention belongs to the technical field of traffic guidance, and in particular relates to a method and a system for rapidly surveying traffic accidents in open space. Background technique [0002] At present: traffic accident refers to the event that the vehicle causes personal injury or property loss due to fault or accident on the road. The current system for managing traffic accidents is the traffic management system. Traffic management systems are used in many geographies to detect and respond to changing traffic conditions. A key area in such traffic management systems is effective accident management, which can help reduce delays caused by traffic accidents and improve the efficiency of the traffic network . Effective management of traffic accidents can include prompt removal of accident vehicles and other debris. However, the existing traffic management system does not have a plan for combining open spaces, which cannot realize accurate ...
