Wearable Vision System 360 Surround View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to enhance real-time situational awareness for individuals in hazardous environments, such as ground forces and first responders, to quickly react to dynamic and unpredictable threats, as existing augmented reality systems do not provide comprehensive 360° visual coverage without obstructing the user's natural field of view.
Innovation Solution
A wearable vision system incorporating multiple cameras and processing units that augment the user's natural vision with a 360° composite field of view, allowing selective display of peripheral views and object detection, using template matching and inertial sensors to adjust camera settings and display based on user cues, including head movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple camera modules are arranged about the outer surface of a wearable unit to provide 360° visual coverage, then situational awareness is enhanced, but the device complexity increases
Solution Approach 1:
The system divides the visual monitoring task into multiple segments by placing camera modules at different locations on the wearable unit. Each camera captures a specific portion of the surrounding environment, and the processing unit integrates these segmented views into a comprehensive composite field of view, achieving 360° coverage without requiring a single complex camera system.
Solution Approach 2:
The system merges multiple video feeds from different camera modules into a single composite field of view displayed to the user. The processing unit combines the visual information from multiple sources, integrating separate camera inputs into a unified augmented reality display that provides complete surround vision.
2Loss of information
If camera vision views are overlaid on the user's field of view to augment situational awareness, then real-time monitoring is improved, but the user's natural eyesight field of view may be obscured
Solution Approach 1:
The system presents camera vision views in a separate dimensional space rather than directly overlaying them on the user's natural field of view. The augmented reality display shows composite fields of view from cameras positioned at different locations, allowing the user to access peripheral and rear views without the displays physically blocking the direct line of sight to the forward environment.
Data Source
AI summary
A portable system providing augmented vision of surroundings. In one embodiment the system includes a helmet, a plurality of camera units and circuitry to generate a composite field of view from channels of video data. The helmet permits a user to receive a first field of view in the surroundings based on optical information received directly from the surroundings with the user's natural vision. The camera units are mounted about the helmet to generate the multiple channels of video data. Each camera channel captures a different field of view of a scene in a region surrounding the helmet.
