Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Pupil diameter detection v1.0 complete (includes VLC for streaming video of eye to software). Video of operation here:
Meeting Steve Roberts to okay our current-controlling object on Tuesday 1/24
Learning how to interface Matlab with Arduino for PID control software
Accomplishments from Previous Week
Finished expanding pupil measurement code to work on video stream. Estimating it can process ~10fps on sponsor's machine ( >5fps preferred). Pending real-life test
Finished learning how to set-up streaming of eye-video through LAN. Awaiting reply from sponsor's IT guy for permission to set it up.
Verified theoretical solution to eliminating LED flicker works.
Tested our LED's at low current (down to .00012 amps) and found no flicker meaning our current control with 12 volt power source should be valid for our prototype
Finished researching on possible ways for current control and options of electronic components (OpAmps, digital potentiometers) required.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
[Wanfang] will run a real-life test on sponsor's laptop to ensure acceptable fps processing capability.
[Wanfang] will help Ji In investigate matlab arduino interface
(Robert) Meeting with Steve Roberts on 1/24 at 1:30 to work out how to do current control with Arduino and basic program for this type of control.
(Robert and Lihua) Finish building prototype with Arduino and basic current control to integrate with the PID components to test with imager
(Lihua) Start purchasing required electronic components
[Ji In] Finish writing control code for closed loop system and test with sample video
