Smart Camera System for Immersive Telepresence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Immersive Telepresence systems face limitations in seating arrangements due to non-overlapping fields of view from cameras, leading to incomplete or distorted images of participants, which are addressed by using overlapping fields of view from ultra-high definition cameras with electronic pan-tilt-zoom capabilities to generate life-size and proportional views.
Innovation Solution
The system employs a cluster of ultra-high definition cameras with overlapping fields of view, utilizing electronic pan-tilt-zoom features and smart camera metrics to generate a combined target view that captures participants at desired proportions, eliminating the need for physical constraints like knee lockers and ensuring all participants are fully captured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cameras with non-overlapping fields of view are used, then the system complexity is reduced and manufacturing is simplified, but the seating arrangement flexibility is limited and image completeness deteriorates
Solution Approach 1:
The patent divides the room into multiple zones, each captured by a dedicated camera with a specific field of view. By segmenting the monitoring space and using overlapping FOVs between adjacent cameras, the system achieves both simplified individual camera setup and flexible seating arrangements, as participants in overlapping zones can be captured by multiple cameras.
Solution Approach 2:
The patent transitions from a two-dimensional non-overlapping camera layout to a three-dimensional overlapping field of view configuration. This dimensional change allows cameras to capture participants from multiple angles and positions simultaneously, providing seating arrangement flexibility while maintaining complete participant capture through the overlapping volumetric coverage.
2Device complexity
If cameras with non-overlapping fields of view are used, then the device complexity is reduced, but the image quality and participant capture completeness deteriorate
Solution Approach 1:
The patent merges the fields of view of multiple cameras by creating overlapping coverage zones. This merging approach combines the strengths of multiple camera perspectives to ensure complete participant capture and maintain high image quality, while the individual camera configurations remain relatively simple and manageable.
3Adaptability or versatility
If overlapping fields of view from ultra-high definition cameras are used, then seating arrangement flexibility and image quality improve, but the device complexity and processing requirements increase
Solution Approach 1:
The patent implements dynamic participant detection and tracking algorithms that automatically identify participants within overlapping fields of view and determine which camera provides the optimal view. This dynamic processing adapts to real-time seating arrangements and participant positions, providing flexibility without requiring complex manual configuration of the camera system.
Data Source
AI summary
Video content is received at a computing device including camera views provided by video cameras that are aligned to capture images of participants within a defined space. The video cameras are aligned such that a field of view (FOV) for each camera overlaps a portion of the FOV of at least one other adjacent camera. Positions of participants depicted within the video content are detected, where target views are generated to combine as a continuous view of the video content that includes the plurality of detected participants. The target views are displayed at display devices.
