UAV Flight Plan Replanning From Interruption Coordinates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight plans for unmanned aircraft inspections may be interrupted due to increased flight distance and power consumption, leading to inefficient data capture and analysis when the aircraft's battery power falls below a threshold, resulting in repeated data capture of the same object portions.
Innovation Solution
A flight plan changing method that identifies the interruption point and generates a new flight plan with adjusted way points, preventing redundant data capture by determining new way points based on the interruption coordinates, thereby optimizing the flight route and reducing data analysis time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the unmanned aircraft flies along the original flight plan to capture image data, then complete inspection coverage is achieved, but flight distance increases and power consumption rises
Solution Approach 1:
The system performs preliminary analysis of the flight log to identify the interruption position before generating the changed flight plan. By determining the exact coordinates where image capture was interrupted, the system can pre-calculate optimized way points that avoid redundant flight paths, thereby reducing power consumption while ensuring complete inspection coverage.
2Reliability
If the flight plan is interrupted and a changed flight plan is generated including way points before and after the interruption position, then the flight can be completed, but image data of the same portion is repeatedly captured
Solution Approach 1:
The system extracts and identifies the specific interruption position coordinates from the flight log. By isolating the exact location where image capture was interrupted, the system can generate a changed flight plan that starts from this specific point rather than repeating from previous way points, thereby avoiding redundant image capture and reducing data analysis time.
Solution Approach 2:
The system performs preliminary identification of the interruption position and pre-calculates the optimized flight path before executing the changed flight plan. This preliminary action ensures that the aircraft directly proceeds to the interruption point and subsequent way points without revisiting already inspected areas, eliminating redundant data capture.
3Reliability
If the changed flight plan includes unflown way points after the interruption position, then complete inspection is achieved, but the amount of captured image data increases
Solution Approach 1:
The system extracts the interruption position coordinates from the flight log and uses this information to selectively include only the necessary unflown way points in the changed flight plan. By precisely identifying where the flight was interrupted, the system generates a streamlined flight plan that captures only the remaining uninspected portions, thereby minimizing the total amount of image data while ensuring inspection completeness.

AI summary
A flight plan changing method performed by an apparatus includes reading a flight log of an unmanned aircraft that flies flight routes connecting multiple way points included in a flight plan and captures image data of an object located between the way points; identifying, based on the flight log, coordinates of a position of the unmanned aircraft at which the capturing of the image data of the object is interrupted; and generating a changed flight plan including way points that are newly determined based on the identified coordinates of the position.
