Feasibility Analysis
Our question:
What is the best option for a camera?
Considerations:
Cost
Built-in display for GUI
Availability of IR in camera
Quality of image
Need for/compatible illumination solutions
Lens attachments
Ability to mount camera solution (fatigue, wear, machining necessary)
Ease of acquisition

6. Feasibility Analysis - Benchmarking
Camera Solution
Cost
Built-in Display?
IR Availability
Illumination Needed?
Lens Attachment Method
Mounting Configuration
Easy to Get?

Detractors
Intel RealSense F200
$99 No
Yes
For RGB cam
Mount/Custom (Embedded)
Over-Device/ Free-Standing
Yes - but small wait
Contains IR and RGB cam, IR projector. Inexpensive
Learning curve, small wait to buy (it's a new product). Would have to implement with a device to interface
Intel RealSense R200
Over-Device/Mount
Contains IR and RGB cam, IR projector. Inexpensive. 3D Manipulation. Face recognition and gestures.
Learning curve, small wait to buy (it's a new product). Has many features not applicable.
Surface 4
$600-$1700
Exists
Mount
Custom Fabrication
No - not yet available
IR camera (RealSense), UI bundled. Immense control over interface (Windows)
Not yet released. Most expensive UI/camera.
P15590 Setup
Analysis needed
Integrated
Working prototype, would only need to improve instead of invent
New design can be implemented for less ost than to improve on old design, does not meet all customer requirement and would require a lot of rework.
iPad
$599
No (requires mod)
Can create app to control colors, exposure and focus, UI bundled.
Not versatile, potential app/licensing issues
Custom Design
Analysis Needed
Integration Dependent
Custom design and implementation
Complete design, implementation not leveraging common use tech.

7. Current Hardware Status
1 Raspberry Pi B+ v1.2
1 Screen with Touch sensor
Touch Sensor has not been integrated
1 Stepper Motor (small)
with driver
1 Camera module (P 15590)

8. Current Software Status
Raspberry Pi has Raspbian Operating System installed
Alpha team created application called ClaRITy
Allows for image capture and storage
Also a testing tool called camTest
Programming in Python
Alpha team created UI in Qt
Software not fully operational - does not perform enough functionality to meet customer requirements
Last known testing yielded image of demo eye with glare from illumination on glass lens
Do we need Python?
