Unmanned aerial vehicle surveying and mapping route planning method, system, equipment and medium

Abstract

The invention provides an unmanned aerial vehicle surveying and mapping route planning method, system and device and a medium, and particularly relates to the technical field of unmanned aerial vehicle flight. Dividing the target operation area into at least one surveying and mapping route segment, wherein the surveying and mapping route segment comprises a parallel round-trip route, a crossed round-trip route or a broken line route; based on the route corresponding to the surveying and mapping route segment, constructing a flight auxiliary route segment to enable the round-trip route or the broken line route to be smoothly joined, wherein the flight auxiliary route segment comprises an extension line of the surveying and mapping route segment, a turning arc waypoint and a linear waypoint; the surveying and mapping route is planned according to the position information of the flight auxiliary legs of the surveying and mapping legs, smooth turning is achieved through the flight auxiliary legs, the turning gradient is small, the turning track is not prone to overshoot, meanwhile, the time needed by the unmanned aerial vehicle for surveying and mapping the route in the target operation area is shortened, and the working efficiency of the unmanned aerial vehicle is improved. And the efficiency of surveying and mapping the route of the unmanned aerial vehicle is also improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method, system, equipment and medium for unmanned aerial vehicle surveying and mapping route planning. Background technique [0002] Unmanned Aerial Vehicle, referred to as Unmanned Aerial Vehicle (UAV), is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAVs are widely used in industries such as agricultural plant protection, surveying and mapping, military defense, emergency rescue and disaster relief, and video shooting. [0003] In related technologies, when fixed-wing UAVs are used for surveying and mapping operations, since the fixed-wing UAVs need a certain space range to turn near the end points of the route, they will deviate from the operation route far away near the end points of the route, or relatively far away from the expected operation. The track produces a large overshoot. In order to ensu...
