UAV Sound Source Guidance for Safe Low-Noise Audio Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicles (UAVs) face challenges in improving sound quality while ensuring the safety of sound sources, as they do not consider the positional relationship between the UAV and the sound source, leading to increased background noise and potential safety risks.
Innovation Solution
An unmanned aerial vehicle equipped with a microphone and processor that determines the quality of the target sound, acquires the positional relationship with the sound source, and presents movement information to guide the sound source to a destination that optimizes sound quality while maintaining safety, using sensors like microphones, image sensors, and distance measuring sensors to adjust the microphone's direction and protrusion or prompting the sound source to change voice volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UAV approaches the sound source to improve sound quality, then the sound quality is improved, but the safety of the sound source deteriorates
Solution Approach 1:
The patent introduces an information presentation device as an intermediary that guides the sound source to move to a safe position. Instead of the UAV directly approaching the sound source, the system uses visual or auditory guidance (arrows, lights, sounds) to mediate the interaction, allowing the sound source to self-position safely while maintaining good sound quality.
Solution Approach 2:
The sound source is empowered to self-position by following the presented guidance information. Rather than the UAV controlling or physically moving the sound source, the system enables the sound source to autonomously move to the optimal safe position based on the guidance received, improving both safety and sound quality.
2Reliability
If the UAV remains at a fixed position, then the safety of the sound source is ensured, but the sound quality deteriorates due to background noise
Solution Approach 1:
The system dynamically adjusts the guidance information based on the real-time positional relationship between the UAV and sound source. As the sound source moves, the presentation position of guidance arrows or lights changes dynamically to maintain optimal sound quality while ensuring safety throughout the movement process.
Solution Approach 2:
The system continuously monitors the positional relationship and sound quality, then provides feedback through the information presentation device. This closed-loop feedback mechanism allows the sound source to adjust its position based on real-time guidance, optimizing sound quality while maintaining safety constraints.
3Measurement precision
If the UAV adjusts the microphone direction and protrusion to improve sound quality, then the sound quality is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical microphone adjustment mechanisms with an information presentation system. Instead of mechanically moving the microphone to optimize sound quality, the system uses visual or auditory guidance to direct the sound source, eliminating the need for complex mechanical adjustment components.
Data Source
AI summary
An unmanned aerial vehicle includes: a sensor including at least a microphone that generates sound data; and a processor. The processor determines a quality of a target sound by using the sound data generated by the microphone, acquires a positional relationship between the unmanned aerial vehicle and a sound source of the target sound by using data generated by the sensor, determines a destination to which the sound source is to move based on the quality of the target sound and the positional relationship, and presents target movement information that prompts the sound source to move toward the destination.
