Multirotor Flight Interface for Stable Aerial Imaging Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remotely controlled multirotor aircrafts face issues with image quality due to pilot skill-dependent vibrations and oscillations, which cause microblur and rolling shutter effects, especially when trying to acquire images from difficult-to-reach positions, as conventional solutions like servo-assisted cardan supports are too heavy for small aircraft and violate weight regulations.
Innovation Solution
A remotely controlled multirotor aircraft system that uses a direction and orientation signal generated by an interface device, such as an earphone/microphone or wand, to control the aircraft's movement and orientation independently of pilot skills, reducing vibrations and oscillations by translating voice commands or movement instructions into control signals for the flight control unit, thereby maintaining image quality regardless of piloting expertise.

Engineering Contradiction Analysis
1Manufacturing precision
If a servo-assisted cardan support is used to correct aircraft orientation during oscillations, then image quality is improved, but the device becomes excessively heavy for small aircraft and violates weight regulations
Solution Approach 1:
The patent replaces the mechanical servo-assisted cardan support system with an electronic/image-processing solution. The flight control unit receives image data from the video acquisition means and determines whether the aircraft is oscillating by analyzing changes in the image data over time. When oscillation is detected, the system controls the video acquisition means to acquire images only during stable periods, eliminating the need for heavy mechanical stabilization components.
2Ease of operation
If conventional remote control actuation is used, then the aircraft is easy to operate, but pilot skill deficiencies cause oscillations and vibrations that degrade image quality
Solution Approach 1:
The system implements a feedback mechanism where the flight control unit continuously monitors image data to detect aircraft oscillations. The system analyzes changes in image data between different time points to determine the oscillation state. Based on this feedback, the system intelligently controls when to acquire images, selecting only those captured during stable flight periods, thereby compensating for pilot control imperfections without adding operational complexity.
