Stereo Illumination Independent Light Source Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic imaging devices face challenges in lighting, as arrangements beneficial for one camera can cause glare or shadows at the other camera due to differences in location and orientation, necessitating a lighting system that can be operated independently for each camera.
Innovation Solution
The system includes a first and second camera with independently operable light sources positioned at their peripheries, allowing for stereo or mono illumination to reduce glare and shadows by capturing images with different illumination effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting arrangement is used that is beneficial for one camera, then the illumination quality for that camera is improved, but glare or shadows are caused at the other camera
Solution Approach 1:
The lighting system is segmented into multiple independent light sources positioned at different locations around each camera. Each light source can be independently controlled to illuminate the scene from different angles, allowing the system to provide beneficial illumination to one camera while minimizing harmful glare or shadows at the other camera through selective activation and independent intensity control of each segment.
2Device complexity
If a single lighting arrangement is used for both cameras, then the system complexity is reduced, but the illumination cannot be optimized for each camera's specific location and orientation
Solution Approach 1:
Each camera is equipped with its own dedicated light sources positioned at its periphery, creating locally optimized illumination conditions tailored to that specific camera's location and orientation. This local quality approach allows each camera to have illumination customized to its specific viewing angle and position, while the overall system remains relatively simple through modular design where each camera-unit is self-contained with its own lighting.

Function Achieved in This Case
This approach enables effective stereo imaging by reducing glare and shadows, enhancing image quality through independent control of light sources, and allowing for the removal of unwanted reflections and shadows through image processing.
Implementation Method 1
a first light source set at a periphery of the first camera for illuminating a region, a second light source set at a periphery of the second camera for illuminating the region
Data Source
AI summary
An imaging device and method of imaging a region. The imaging device includes a first camera and a first light source set at a periphery of the first camera, a second camera separated from the first camera by a selected distance and a second light source set at a periphery of the second camera, and a processor configured to operate the first light source set and the second light source set independently of each other. The region is illuminated using the first light source and a first image is obtained. The region is illuminated using the second light source and a second image is obtained. At least one of the first image and the second image includes an illumination effect.
