Road section safety warning method, device and unmanned aerial vehicle

Abstract

The present invention provides a warning method, device and unmanned aerial vehicle for road section safety, including: if a safety warning task is received, the task route carried by the safety warning task is based on the task route to sail to the target task point; wherein, the task route is based on the target task point Obtained by planning; collecting the image of the first road section at the target task point; identifying the second degree of congestion corresponding to each candidate warning direction at the target task point based on the image of the first road section; if the second degree of congestion corresponding to the candidate warning direction is higher than the predicted Set the congestion threshold, determine the candidate warning direction as the target warning direction of the UAV; navigate according to the target warning direction, and carry out road section safety warnings during the navigation process, and hover until the target hovering point is reached; among them, the target hovering The stopping point is determined based on the first degree of congestion corresponding to the traffic section. The present invention can significantly improve the alarm timeliness and alarm effect, and can also effectively reduce the alarm cost.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a road section safety warning method, device and unmanned aerial vehicle. Background technique [0002] On highways, traffic accidents often lead to traffic jams, but at night or in bad weather such as low visibility, due to poor light, it is very easy for drivers behind to see the road conditions ahead, and they cannot brake in time to slow down and cause secondary accidents, etc. However, the traditional way of dispatching police has problems such as low timeliness, poor inspection effect, and high cost. Contents of the invention [0003] In view of this, the object of the present invention is to provide a warning method, device and drone for road section safety, which can significantly improve the timeliness and effect of warning, and can also effectively reduce the cost of warning. [0004] In the first aspect, the embodiment of the present invention provi...
