Embodiment Construction

[0041] The embodiment of the present application provides a track planning method based on the potential field method, which solves the technical problem that the aircraft track planning in the prior art cannot adjust the track in real time, and then realizes the real-time planning of the track. technical effect.

[0042] The technical solution in the embodiment of this application is to solve the technical problem that the above-mentioned aircraft track planning cannot adjust the track in real time, and the general idea is as follows:

[0043] First, the aircraft obtains the characteristic information of obstacles in the determined geographical environment abstractly according to the determined geographical environment in the process from the flight starting point to the destination; then, according to the obtained characteristic information, the potential field method is used to obtain the distance between the aircraft and the destination. The resultant force; finally, accor...

Abstract

The invention discloses a track planning method based on a potential field method, which is characterized in that it includes the following content: According to the determined geographical environment in the process of the flight from the starting point of the aircraft to the destination, abstractly obtain the characteristics of obstacles in the determined geographical environment information, and save the feature information; based on the feature information, the potential field method is used to obtain the resultant force between the aircraft and the terminal; based on the resultant force, the control updates the current position, which solves the problem that the aircraft track planning in the prior art cannot be adjusted in real time. Technical problems, and then achieved the technical effect of being able to plan the trajectory in real time.

Description

technical field [0001] The invention relates to the technical field of UAV track planning, in particular to a track planning method based on a potential field method. Background technique [0002] The trajectory planning of the aircraft refers to planning the best path according to various factors such as the specific mission of the aircraft flight, threat volume, weather conditions, air position and terrain data under the constraint conditions. , which needs to meet two indicators: one is to require the amount of various threats to be as small as possible during the planning process, and the other is to require the path to be as short as possible. [0003] According to different mission performance indicators, the aircraft trajectory planning algorithm also has different requirements. In the process of aircraft trajectory planning, it is necessary to consider the influence of various factors on the aircraft during the flight process. Under the condition of mutual coupling ...
