Computer Vision Gimbal Tracking for GPS Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GPS-enabled tracking systems for capturing dynamic subjects in three-dimensional spaces face limitations, such as dependency on GPS signals, obstructions, and the need for the subject to carry a tracking device, leading to inaccuracies and difficulties in capturing movements in complex environments.
Innovation Solution
A system comprising a pivoting device (gimbal) with a camera, a main computing system, and a gimbal stabilizer controller, which uses computer vision algorithms and object detection methods to track subjects in 3D spaces, allowing for real-time adjustments and stabilization of the camera's position and orientation, independent of the cameraperson's expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS-enabled tracking system is used, then location tracking is enabled, but accuracy deteriorates due to obstructions and multipath errors in three-dimensional spaces
Solution Approach 1:
The patent replaces GPS-based tracking with a computer vision-based tracking system. Instead of relying on satellite signals and GPS receivers, the system uses cameras to capture images and computer vision algorithms to detect and track the target's position and orientation in three-dimensional space, eliminating GPS-related accuracy issues in obstructed environments
Solution Approach 2:
The patent introduces computer vision algorithms as an intermediary between the camera and the tracking system. The algorithms process camera images to extract target position and orientation data, serving as a mediator that enables accurate tracking without direct GPS signal dependency
2Reliability
If subject carries tracking device, then tracking capability is enabled, but ease of operation deteriorates due to complexity of setup and operation
Solution Approach 1:
The patent inverts the traditional tracking approach by placing the camera on the tracking device (camera mount) rather than requiring the subject to carry a GPS receiver or tracking device. The camera-mounted system passively observes and tracks the subject, eliminating the need for subject involvement in the tracking process
Solution Approach 2:
The computer vision system automatically detects, identifies, and tracks the target without requiring manual intervention or subject cooperation. The system self-adjusts to maintain target acquisition, performing the tracking function autonomously once the camera is positioned
3Reliability
If conventional camera tracking is used, then capturing capability is enabled, but productivity deteriorates due to need for expert cameraperson
Solution Approach 1:
The camera mount system with computer vision algorithms performs automatic target tracking and positioning without requiring skilled operation. The system autonomously adjusts camera orientation to follow the target, eliminating the need for expert camerapersons and enabling untrained users to achieve professional-quality tracking shots
Solution Approach 2:
The patent replaces manual camera operation with automated computer vision-based control. Instead of relying on a cameraperson's expertise to manually track and frame the subject, the system uses image processing algorithms to automatically determine and execute the optimal camera positioning and orientation
