Flight Vehicle Illumination Control for Precise Tilted Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flight vehicles equipped with cameras face challenges in obtaining highly precise images due to difficulties in standing still and vibrations caused by wind and propeller rotation, making it hard to detect structural defects in infrastructure such as bridges and roads.
Innovation Solution
A control device and method that adjusts the light amount of an illuminating device based on the inclination of the flight vehicle's body to maintain uniform illuminance, combined with attitude control of the imaging device to compensate for vibrations and ensure precise imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a flight vehicle with a camera mounted thereon is used to photograph targets, then the photographable range is extended and access to difficult-to-reach places is enabled, but the image precision is reduced due to vibrations from wind and propeller rotation
Solution Approach 1:
The patent introduces an illuminating device as an intermediary component mounted on the flight vehicle. This device provides active illumination to the photographing target, enabling precise imaging in low-light conditions without requiring the flight vehicle to hover stationary for extended periods, thereby mitigating the impact of vibrations on image quality while maintaining extended photographable range
Solution Approach 2:
The patent adjusts illumination parameters (light amount, illumination angle) based on the flight vehicle's inclination angle. By dynamically changing illumination parameters to compensate for vehicle movement, the system maintains image precision despite the flight vehicle's inability to remain completely stationary due to wind and propeller vibrations
2Illumination intensity
If the light amount of the illuminating device is increased to compensate for vibration-induced illumination changes, then the illuminance uniformity is improved, but the energy consumption increases
Solution Approach 1:
The control device dynamically adjusts the light amount of the illuminating device based on the inclination angle of the flight vehicle. When the vehicle is more inclined, the light amount is increased to maintain illuminance uniformity; when the vehicle is more stable, the light amount is reduced. This adaptive parameter adjustment maintains image quality while minimizing energy consumption
Solution Approach 2:
The system implements a feedback control mechanism where the control device receives inclination angle information, processes it to determine the appropriate light amount, and adjusts the illuminating device accordingly. This closed-loop feedback ensures illuminance uniformity is maintained while optimizing energy usage based on actual flight conditions
