Radius-Based Vehicle Tracking for Abrupt Subject Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controlled vehicles struggle to maintain a consistent tracking of moving subjects due to reliance on user control, which is cumbersome and prone to losing track when the subject moves unexpectedly.
Innovation Solution
A vehicle system that includes a camera, a radius generator, and a vehicle controller interface, which dynamically generates a virtual sphere around the vehicle based on velocity and camera configuration data to autonomously adjust the vehicle's position and camera orientation, ensuring smooth tracking of moving subjects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user control is used to follow the moving subject, then the vehicle can be controlled to capture images, but the operation becomes cumbersome and the subject may be lost when moving unexpectedly
Solution Approach 1:
The system enables autonomous tracking where the vehicle automatically follows the moving subject without requiring continuous user input. The radius tracking controller independently calculates target positions and controls the vehicle to maintain the subject within the virtual sphere, making the system self-sufficient and eliminating the need for cumbersome manual control while ensuring reliable tracking even when the subject moves unexpectedly
Solution Approach 2:
The system continuously monitors the subject's position relative to the virtual sphere and dynamically adjusts the vehicle's movement to maintain proper tracking. The radius tracking controller uses real-time position data to calculate updated target positions, creating a closed-loop feedback system that automatically responds to subject movement and maintains reliable tracking without user intervention
2Stability of the object's composition
If the vehicle autonomously adjusts position and camera orientation dynamically, then smooth tracking of moving subjects is achieved, but the device complexity increases
Solution Approach 1:
The system dynamically generates a virtual sphere with a radius that adapts to the subject's movement characteristics and adjusts the vehicle's target position in real-time. This dynamic approach allows the tracking parameters to automatically respond to changing conditions, maintaining stable tracking of moving subjects while the control logic handles the complexity of continuous adjustment
Solution Approach 2:
The virtual sphere acts as an intermediary concept that simplifies the control problem. Instead of directly controlling complex camera and vehicle movements, the system uses the virtual sphere as a reference framework to determine target positions. This intermediary abstraction manages the complexity by providing a clear geometric relationship between the vehicle, subject, and camera, enabling smooth tracking through systematic position calculation
