Embodiment Construction

[0016] The present invention will be described in further detail below. A flight track planning method for an unmanned helicopter, which uses a map drawing control to add map functions to the track planning application, and realizes determining track points on a high-precision digital map by clicking with a mouse and modifying the track by dragging a mouse. track point, and the helicopter-specific flight performance such as hovering characteristics is considered in the planning constraints. The method includes the following steps:

[0017] (1) Add the map function to the unmanned helicopter track planning system by using the map drawing control;

[0018] (2) According to the target requirements, click on the corresponding position on the digital map to determine the track point. If you need to adjust its position, drag it directly to another position;

[0019] (3) Set mission requirement attributes for track points, including hovering points, transition points, and passing p...

Abstract

The invention belongs to the field of unmanned helicopter flight track planning, and relates to a fast flight track planning method aiming at an unmanned helicopter. The unmanned helicopter flight track planning method adopts a mapping control to add the map function into the flight track planning application, realizes flight track point confirmation through mouse selecting and flight track point modification through mouse dragging on a high accurate digital map, and considers specific flight performances of the helicopter during constraint condition planning, such as the hovering characteristic. The method solves the problem of practicability in unmanned helicopter flight track planning, requires no manual edition of flight track point coordinate position, is convenient to operate, is fast in planning, and has high interactivity.

Description

technical field [0001] The invention belongs to the field of unmanned helicopter track planning, and relates to a fast track planning method for unmanned helicopters. Background technique [0002] Because unmanned helicopters are different from unmanned fixed-wing aircraft in hovering characteristics and ultra-low-altitude flight characteristics, the commonly used trajectory planning methods for unmanned fixed-wing aircraft are not suitable for unmanned helicopters. At present, domestic unmanned helicopters mainly use manual calculation and manual editing to input waypoints for trajectory planning. The process is cumbersome, time-consuming to modify, and less convenient to use. Contents of the invention [0003] The technical problem to be solved in the present invention: [0004] The invention proposes a convenient, practical and quick unmanned helicopter track planning method. [0005] Technical scheme of the present invention: [0006] A method for planning a flight ...
