Rescue aircraft path planning method and system based on flight safety

Abstract

The invention relates to a rescue aircraft path planning method and system based on flight safety. The method comprises the steps of acquiring a terrain environment of a disaster area; based on rescueconstraint conditions, performing three-dimensional modeling on the terrain environment of the affected area to obtain an environment three-dimensional model, wherein the rescue constraint conditionscomprise rescue aircraft performance and low-altitude flight rules; acquiring a rescue model taking maximum rescue efficiency as an optimization target; based on the environment three-dimensional model and the rescue model, performing path planning by adopting an ant colony algorithm in a flight constraint condition to obtain a reference path from a starting point to a target point in a disasterarea; and smoothing the reference path to obtain a flight path of the rescue aircraft. According to the invention, the path planning efficiency can be improved and the rescue speed is accelerated.

Description

technical field [0001] The invention relates to the field of path planning, in particular to a flight safety-based rescue aircraft path planning method and system. Background technique [0002] In recent years, various disasters have occurred frequently in countries all over the world. After disasters, relief materials are often not delivered in time, making it difficult to carry out rescue accurately and quickly, which further aggravates the impact of disasters. According to many characteristics of rescue aircraft, it can participate in the delivery of disaster relief materials. How to safely and efficiently complete the delivery of disaster relief materials and improve emergency rescue capabilities requires planning the flight path of rescue aircraft. [0003] When natural disasters occur, especially in mountainous areas, aircraft is the most important means of rescue. However, due to the particularity of complex low-altitude emergency rescue flights and the interference...

AI Technical Summary

Problems solved by technology

However, due to the particularity of complex low-altitude emergency rescue flights and the interference of uncertain factors such as terrain obstacles, aviation emergency rescue will face problems such as high rescue risks and low rescue efficiency.

In addition, the key to path planning technology lies in the selection and use of path planning algorithms. Traditional search algorithms
