Camera Tracking Digital Twin Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating digital twin content that covers a wide range of space while minimizing the number of cameras used, as existing methods require multiple cameras to track and simulate objects in real-world spaces, leading to increased costs and resource utilization.
Innovation Solution
A method using a computer system with a camera and a driving unit to automatically control the camera's rotation and zoom level, allowing for the creation of digital twin content by identifying and tracking objects, and representing their movement in a virtual space with a smaller number of cameras through iterative parameter determination and control result value processing.

Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are used to track and simulate objects in real-world spaces, then the coverage of space and tracking accuracy are improved, but the cost and resource utilization increase
Solution Approach 1:
The patent applies dynamics by making the camera rotatable and zoomable, allowing a single camera to dynamically adjust its field of view and tracking parameters. The camera can rotate to follow object movement and zoom to maintain optimal viewing distance, replacing the need for multiple fixed cameras to cover the same space.
Solution Approach 2:
The single camera system performs multiple functions that would traditionally require multiple cameras: it can pan across different areas, zoom to capture distant objects, and track moving objects. This multi-functional capability allows one camera to replace several cameras while maintaining comprehensive space coverage.
2Quantity of substance
If a single camera is used to minimize resources, then cost and resource utilization are reduced, but the ability to track objects across wide space is limited
Solution Approach 1:
The camera system is made dynamic with rotational and zoom capabilities, allowing it to adapt to different tracking scenarios. The camera can rotate to follow objects moving across the field of view and zoom to maintain appropriate scale, enabling a single camera to track objects effectively across wide spaces.
Solution Approach 2:
The system uses feedback mechanisms where the camera's rotation and zoom levels are continuously adjusted based on object position and movement. This feedback loop enables the single camera to maintain optimal tracking performance across varying distances and positions, enhancing its versatility.
3Measurement precision
If camera rotation and zoom are manually controlled, then tracking precision is improved, but the complexity of operation increases
Solution Approach 1:
The camera system performs self-service by automatically adjusting its rotation and zoom levels based on object detection and tracking algorithms. The system autonomously determines the optimal camera parameters to maintain the object within the frame at the appropriate scale, eliminating the need for manual control while maintaining high tracking precision.
Solution Approach 2:
The patent replaces manual mechanical control with automated electronic control systems. Sensors and processors automatically adjust camera parameters based on real-time object position data, substituting human operation with automated mechanisms that achieve higher precision and consistency.

AI summary
Provided is a method of creating digital twin content for a space based on object recognition in the space. A method of creating digital twin content includes identifying, by a computer system, an object in a space using a camera, determining a value of a parameter associated with the camera to define (or display) the identified object with a predetermined first size at a predetermined location on an image captured by the camera or a screen on which the image is displayed, and using a control result value based on the determined value of the parameter and the location information of the identified object to create the digital twin content for the space.
