Solution Overview

Problem

Current methods for tracking mobile targets by aircraft, such as UAVs, require external radio control and are not efficient in minimizing uncertainty in target positioning, especially in dynamic environments.

Innovation Solution

A method that uses image analysis from onboard cameras to identify and track mobile targets by determining their coordinates in a Global Reference System, minimizing uncertainty through a pinhole camera model and eigenvalue calculations, allowing aircraft to autonomously adjust their position for optimal tracking without external control.

Solution Approach 2:

The patent replaces complex mechanical control systems with optical and computational systems. By using onboard cameras to capture images and algorithms to process them, the system substitutes mechanical maneuver control with optical-field-based autonomous positioning, reducing mechanical complexity while improving tracking reliability

Solution Approach 1:

The aircraft performs autonomous target identification and tracking using onboard cameras and image processing algorithms. The system independently determines its own positioning relative to mobile targets without requiring external radio control commands, achieving full automation while simplifying operation through autonomous decision-making

Inventive Principle:

3Measurement precision

If aircraft maintain fixed position to monitor mobile targets, then measurement precision of target coordinates is improved, but productivity decreases due to limited field of view

Engineering Contradiction:

Solution Approach 1:

The aircraft dynamically adjusts its position and orientation based on real-time image analysis. Instead of maintaining a fixed position, the aircraft moves autonomously to optimize its viewing angle and distance to the target, thereby maintaining measurement precision while expanding the effective field of view and monitoring efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses onboard cameras to continuously capture images of the target and surrounding environment. This visual feedback is processed to determine the aircraft's relative position to the target, and the information is fed back to adjust the aircraft's positioning in real-time, achieving both precision and efficiency

Inventive Principle:
Principle #23Feedback
