Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in accurately determining the positional coordinates of a target object, especially when the object is moving or does not have fixed positional coordinates, which hinders effective UAV aerial photography and videography.
Innovation Solution
A method involving an unmanned aerial vehicle (UAV) communicatively connected with an electronic device, where the UAV receives a wireless signal including a direction of illumination to orient its image sensor, capture video data, and determine the target object's positional coordinates using patterns, temporal frequencies, or distance information from the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used for target identification and tracking, then the system can capture images and video of stationary targets, but it fails to accurately determine positional coordinates of moving objects without fixed coordinates
Solution Approach 1:
The patent introduces a wireless signal as an intermediary carrier that conveys directional illumination information from the electronic device to the UAV. This signal acts as a mediator that enables the UAV to determine the position of moving objects without requiring pre-known coordinates, thereby resolving the contradiction between measurement precision and adaptability to moving targets
Solution Approach 2:
The patent replaces traditional mechanical tracking systems with an optical-based solution using directional illumination patterns and wireless signal processing. Instead of relying on physical coordinate systems or mechanical positioning, the system uses light direction analysis and signal processing to determine positional coordinates, enabling accurate tracking of moving objects
2Ease of operation
If the user provides precise positional information manually, then the UAV can capture images of the target, but the process becomes complex and difficult when the target is moving or lacks fixed coordinates
Solution Approach 1:
The system enables the electronic device to automatically determine and transmit its own positional information through wireless signals containing directional illumination data. The UAV autonomously processes this information to calculate target coordinates without requiring manual user input, making the system both easy to operate and precise for tracking moving objects
Solution Approach 2:
The system establishes a feedback loop where the electronic device continuously emits wireless signals with directional information, the UAV receives and processes these signals to determine position, and the system automatically adjusts tracking based on the calculated coordinates. This closed-loop feedback mechanism eliminates manual intervention while maintaining high positional accuracy

AI summary
An unmanned aerial vehicle (UAV) may have a positional sensor and an image sensor. The UAV may receive from an electronic structure a first wireless signal. The first wireless signal may include a first direction of illumination. In accordance with the first wireless signal, the UAV may identify a target object based, at least in part, on the first direction of illumination. The UAV may also determine positional coordinates of the target object.
