Virtual Video Streams for Dynamic 3D Surveillance Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing and testing video surveillance management systems are hindered by legal restrictions on video source material, limiting the creation of complex scenarios involving people and property, and training is restricted due to inadequate video feeds, making it difficult to simulate dynamic and realistic environments for training operators.
Innovation Solution
A computer-implemented method and apparatus that generates virtual video streams from a dynamic 3D virtual environment, allowing for the creation of real-time video footage of virtual people and property, which can be integrated into a video management system, enabling the simulation of complex scenarios and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real video footage from surveillance cameras is used for development and testing, then training scenarios can be created, but legal restrictions prevent using video material showing people and personal property
Solution Approach 1:
The patent creates virtual copies of real-world environments, people, and objects in a 3D virtual space. Instead of using actual video footage containing personal property, the system generates synthetic video streams from virtual models that replicate human behavior, physical environments, and surveillance scenarios without legal restrictions
Solution Approach 2:
The patent transitions from 2D video feeds to a 3D virtual environment that can be viewed from multiple angles and perspectives. The 3D virtual space allows operators to interact with the environment spatially, providing depth and dimensional information that enhances training realism while avoiding legal issues associated with real video footage
2Ease of operation
If fixed video feeds are used for training, then operator training can be conducted, but the same repeating situations offer no interaction options
Solution Approach 1:
The patent transforms static video feeds into dynamic 3D environments where virtual objects, people, and scenarios can change in real-time. Operators can interact with the virtual environment by controlling virtual cameras, manipulating objects, and triggering different scenarios, making the training adaptive rather than fixed
Solution Approach 2:
The system provides interactive feedback mechanisms where operator actions in the virtual environment produce immediate visual and operational consequences. Virtual people respond to operator commands, scenarios evolve based on decisions made, and the system tracks performance metrics, creating an engaging interactive training experience
3Productivity
If older and inadequate video material is used due to legal limitations, then development can continue, but the video material cannot depict complex scenarios involving people, behavior and properties
Solution Approach 1:
The patent creates virtual replicas of complex real-world scenarios including diverse human behaviors, property interactions, and environmental conditions. These virtual copies can depict any scenario imaginable without legal constraints, allowing developers to test software with highly complex and varied situations that would be impossible to capture legally in the real world
Data Source
AI summary
A computer implemented method of operating a video management system, the method comprising inputting, into the video management system, a plurality of virtual video streams generated by virtual video cameras within a dynamic 3D virtual environment; receiving, in the computer, at least one command from a user indicative of an instruction to alter a functioning of the dynamic 3D virtual environment and/or a functioning of the video management system; and displaying on a display, from the video management system, at least one virtual video stream and/or at least one alert, alarm and/or message implementing at least one alteration caused by the received command.
