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!
