This week was again spent on the requirements document. Grady and I met on Tuesday to work on it and we all met on Thursday for a few hours to wrap it up. We updated the screenshots, finished the document including making changes based on Dr. Wolff's edit suggestions, made the Gantt chart, and made a Google Sketchup diagram of the scene we will be setting up.
It is nice to have this document done. As far as the team, we probably should have been a little better at communicating for Tuesday as Tyler's phone ended up being dead and thus not knowing about meeting. We should have set it up more in advance.
However, Thursday was good and we got a good amount done.
Grady was able to do some more research into the hardware as well.
All in all a pretty successful week. Now to get back to the actual design... :)

Week of 10/15
This week was spent entirely on the presentation and requirements document. We met on Monday to review for the presentation which was on Tuesday. It went fairly well..kind of long because of a lot of questions. As Dr. Wolff suggested, we should have had more pictures to help explain what was going on (which we then discussed after class, trying to nail down for ourselves how the line gives depth).
We met on Thursday to work on the requirements document. We sent a rough draft to Dr. Wolff. We have the following items to work on before the due date next Thursday:
Our team is still doing pretty good and we are ready to continue working in the second half of the semester.
Enjoy the break!

- Finish up the Introduction (need to incorporate the background research we have done)
- Task breakdown
- Preliminary Timetable (Gantt chart)
- Annotated Bibliography

Enjoy the break!

Week of 10/8 Progress
Not much to report for this week. We met on Monday and worked some on our requirements document. We still have quite a bit to do. We will be presenting our requirements on Tuesday 10/16. We are going to meet this Saturday to work on the req. doc and presentation, hopefully getting a large chunk done.
Other than that, we may also try and extend last week's progress with the red line and plot a row of pixels' red intensity.
The team is good; we all contributed input for the document and will continue to work together this weekend.
Hope to have a rough draft done by 10/18. After the requirements are done, hopefully we can continue making progress on the design (e.g. the stage, Grady with the motor).

Week of 10/1
Since my last post, I did some research on the webcam we will be using and found that the Logitech software doesn't persist settings upon reboot. We haven't yet tested this ourself though.
On Tuesday, I went through Chapter 11 of the OpenCV book on Camera calibration, etc. before our faculty meeting. During our faculty meeting, we hacked through some more of the math of obtaining a plane in world coordinates. We also were able to get the motor and laser line.
On Thursday, our group met and began testing out the laser line with the camera. We tried to isolate the red component of the laser, but it was not very successful. We were able to tweak some of the webcam settings and were able to get a pretty good result of isolation of the laser in a dark room (by converting the BGR image to a HSV (Hue Saturation Value) and obtaining the pixels within a certain HSV range). The final settings will likely not be persisted upon reboot, so we will likely need to find a way to do this from OpenCV. The webcam settings used do wash out a regular image, but the colors in the image are still clear enough to hopefully be able to be used as a color component for our 3D polygonal mesh.
We also began working on our requirements document, and Grady began researching how to inyegrate the stepper motor with software.
Our team progress this week was not ideal, but was ok. Next week, we will continue working on the requirements document. Grady may also continue researching the motor implementation; and we may try and figure out the settings for the webcam in OpenCV.
Personal assessment for this week is I feel I contributed a good amount. Probably should have done more research from the Brown sites though. Team assessment: pretty good ending to an otherwise slow week. We were able to meet for about 5 hours and work through the first look of the laser-camera interaction.
Intrinsics/distortion parameters still loom in the future...
Anyways, Go Huskies!
