Overhead Camera Fixture for Unobstructed Facility Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring inventory movement and user identification in materials handling facilities lack efficient and unobtrusive methods for capturing images from multiple angles, leading to potential obscuration of objects and reduced camera visibility.
Innovation Solution
The use of camera fixtures with strategically positioned user identification and item identification cameras, along with light sources, mounted on overhead structures to minimize obscuration and enhance image acquisition, allowing for unobtrusive and effective monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cameras are mounted at typical positions in the facility, then image acquisition is possible, but objects may be obscured and camera visibility is reduced
Solution Approach 1:
The patent transitions camera mounting from traditional wall or floor positions to overhead suspension, utilizing the vertical dimension to achieve superior imaging angles. This dimensional change eliminates obscuration by positioning cameras above the plane of activity, providing unobstructed views of inventory and users without blocking sightlines.
Solution Approach 2:
The patent introduces an overhead fixture or suspension system as an intermediary structure to mount cameras. This intermediary platform positions cameras at optimal heights and angles while remaining unobtrusive, allowing clear observation of facility activities without the cameras themselves becoming obstacles or being easily accessible for tampering.
2Productivity
If multiple cameras are deployed for comprehensive coverage, then monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple cameras into a single integrated overhead fixture or suspension assembly. This merging approach allows multiple imaging devices to be positioned at optimal angles and heights within a unified structure, achieving comprehensive coverage while simplifying installation, maintenance, and system management compared to distributed camera placements.
Solution Approach 2:
The overhead fixture or suspension system serves multiple functions: it positions multiple cameras for comprehensive coverage, provides structural support, enables easy adjustment of camera angles, and maintains an unobtrusive presence in the facility. This multi-functionality reduces overall system complexity while enhancing monitoring capabilities.
3Measurement precision
If cameras are positioned for optimal image acquisition, then image quality improves, but cameras become more vulnerable to tampering
Solution Approach 1:
By suspending cameras from the ceiling or overhead structures, the patent places imaging devices in a vertical dimension that is difficult to access from ground level. This dimensional relocation maintains optimal imaging angles while naturally protecting cameras from tampering, as users would need to reach overhead to access the devices.
Solution Approach 2:
The overhead fixture or suspension system acts as an intermediary barrier between the cameras and potential tamperers. This intermediary structure positions cameras at secure heights and can incorporate locking mechanisms or protective housings, making it difficult to access or damage the cameras while preserving their optimal positioning for image acquisition.

AI summary
An overhead fixture supports a plurality of cameras used to acquire images associated with a scene during operation of a facility. In one implementation, a first camera is mounted to the overhead fixture to acquire one or more images of a user, while a second camera is mounted to the overhead fixture to acquire one or more images of an inventory location or items at the inventory location. One or more light sources may be mounted on the overhead fixture and activated to produce light. The light may illuminate one or more of the user, the items at the inventory location, or other portions of the scene. Brilliance of the light sources may also obscure the cameras from observation by the user.
