UAV Flight Aiding Control for FPV Direction Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of unmanned aerial vehicles (UAVs) face challenges in maintaining control, especially at distances where the UAV is difficult to visually track, leading to potential loss of direction and reduced user experience due to the need to focus on a display screen in First Person View (FPV) mode.
Innovation Solution
A flight aiding system and method that allows UAVs to receive instructions to execute a flight aiding function, record a point of interest and current location, and define a forward flight direction, enabling operators to control the UAV's path without taking their eyes off the display, using wireless communication and GPS for navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator operates the unmanned aerial vehicle in First Person View (FPV) mode and focuses on the display screen, then the operator can observe the flight view, but the operator may lose track of the UAV's position and direction, causing the UAV to get lost
Solution Approach 1:
The patent implements a feedback mechanism by providing real-time visual information about the UAV's position, heading angle, and flight path on the display screen. The system continuously feeds back the UAV's actual flight status to the operator, allowing the operator to monitor the flight path without diverting attention from the FPV display. This resolves the contradiction by enabling both FPV observation and position awareness simultaneously through integrated visual feedback.
Solution Approach 2:
The patent introduces an intermediary system (the flight path display and heading angle indicator) that mediates between the FPV display and the operator's need to track UAV position. Instead of requiring the operator to directly observe the physical UAV, the intermediary visual indicators on the screen provide indirect but sufficient information about the UAV's orientation and position relative to the flight path, eliminating the need to switch attention between the FPV and the physical UAV.
2Speed
If the operator operates the unmanned aerial vehicle at a distance of four or five hundred meters, then the UAV can cover larger areas, but it becomes difficult to see the UAV clearly with naked eyes, leading to blind flying
Solution Approach 1:
The patent introduces visual intermediary indicators (heading angle display and flight path markers) on the operator's display screen that serve as mediators between the operator and the distant UAV. These intermediaries provide real-time visual information about the UAV's orientation and position without requiring direct visual observation of the physical UAV, enabling effective operation at distances of four or five hundred meters while eliminating blind flying.
Solution Approach 2:
The patent replaces the mechanical visual observation system (operator's naked eyes directly tracking the physical UAV) with an electronic information system that displays heading angles and flight path data on the screen. This substitution allows the operator to detect and measure the UAV's position and orientation electronically rather than mechanically through direct visual observation, solving the detection difficulty at long distances.
3Reliability
If the operator needs to observe the position of the unmanned aerial vehicle while watching the FPV, then the operator can maintain awareness of the UAV, but the user experience is reduced due to divided attention
Solution Approach 1:
The patent merges the FPV display with the flight path information display into a single integrated visual interface. The heading angle indicator and flight path markers are overlaid or integrated with the FPV video feed, allowing the operator to simultaneously observe both the flight view and the UAV's position information without dividing attention between separate displays. This merging resolves the contradiction by providing both reliability and ease of operation through a unified visual interface.

AI summary
A flight aiding method for an unmanned aerial vehicle includes receiving a receiving, from a mobile terminal that controls the unmanned aerial vehicle, a flight aiding instruction to execute a flight aiding function. The flight aiding method further includes in response to receiving the flight aiding instruction, controlling, regardless of a head direction that a head of the unmanned aerial vehicle is pointing, the unmanned aerial vehicle to fly by controlling both a velocity of the unmanned aerial vehicle along a reference direction and a velocity of the unmanned aerial vehicle perpendicular to the reference direction. The reference direction is defined for the unmanned aerial vehicle based on a position of a point of interest and a current location of the unmanned aerial vehicle.
