Single-Camera Virtual Field of View for Patient Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video surveillance systems for patient monitoring in healthcare environments struggle to balance high-resolution focus on regions of interest with maintaining an overall environmental context, especially with limited equipment.
Innovation Solution
A system generates a virtual field of view that combines an environment view with detailed views of specific regions of interest using a single camera, employing various imaging modalities and algorithms to capture and process video data, allowing for efficient monitoring of patient parameters and equipment status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single camera is used for patient monitoring, then device complexity is reduced, but the ability to capture both wide-area context and detailed region information deteriorates
Solution Approach 1:
The patent segments the visual information by dividing the environment view into multiple regions of interest (ROIs). The processing device identifies and extracts specific ROIs from the wide-area environment view captured by the single camera, allowing detailed analysis of particular areas while maintaining the overall contextual view. This segmentation enables the system to focus computational resources on relevant regions without requiring multiple physical cameras.
2Measurement precision
If high-resolution video is captured for detailed monitoring, then measurement precision is improved, but the overall environmental context is lost
Solution Approach 1:
The patent resolves the resolution-field of view tradeoff by adding a temporal dimension to the solution. The system captures environment views at lower resolution continuously, while capturing detailed ROI views at high resolution periodically or on-demand. This multi-resolution, multi-temporal approach allows the system to provide both wide-area context and detailed information without being constrained by the traditional spatial tradeoff of a single camera view.
Data Source
AI summary
A system for remotely monitoring a patient in a patient environment. The system receives an environment view and determines one or more objects for monitoring in the environment view. The system receives video data of the one or more objects. The video data is captured by a camera positioned inside the patient environment. The system generates a virtual field of view using the video data of the one or more objects. The virtual field of view provides the environment view and detailed views of the one or more objects within the environment view.
