Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Continuing to fine tune ellipse fit of fly wings, through adjusting the learning rate and thresholds. The learning rate adjusts the amount of time the code takes to learn patterns and helps improve performance. The thresholds adjust the level of background subtraction and criterion for ellipse fit.
Currently working on projection method. Starting last week we have begun testing with projection onto a 4 inch sphere. To do this we painted the outside of the test sphere with white paint so we can see the projected image. Thus far we have tested a manual manipulation and camera calibration to fit image to sphere.
We have received parts for the costume back light. Unfortunately, the processs of sodering the LEDs to the protoboard appears to be daunting task. This is due to the size of the LEDs and protoboard. We are now going to look into printed circuit board for the back light.
We are still waiting for the spherical display structure and the fillers for the IR laser. We will be able to begin testing with the laser as a back light once the filters arrive.
Accomplishments from Previous Week
Recorded videos of tethered fly at multiple frame rates
Prepare proof of concept presentation.
Completed integration of image subtraction and ellipse fit to tethered fly wing. (fine tuning is still needed)
Laser cut mounts for mirrors used in projection.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Complete projection onto sphere.
Test IR laser as back light. (when filters arive)
Work to complete angel detection.
Start feedback portion of code.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
At the last meeting the sponsor thought that we were on track with the project and was happy with our progress. He also suggested looking into a pcb for a new back light. In response we have been looking into the matter and hope to have a one ordered by the beginning of next week.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
At the last meeting the instructor suggested making a wing angel against vs. time to determine if hypothesis made in presentation about a fly's wing beats is true. At our last meeting the team discussed this and will be working to produce such a graph shortly.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Regarding the presentation. we had some comments about not having enough pictures in our slides and that some of the videos were to long. The majority of the comments though focused on how they liked the order and presentation.
Risks and Areas of Concern

Budget (list amount spent and amount remaining)
Point Gray USB 3, Flea 3 1280X1024 high speed camera. ($600.00)
Macro zoom lens ($1000.00)
Other parts have been ordered. Will update the budget once we have obtained the invoice from our sponsor.
Amount remaining ($3,400.00)
Progress on Report and Webpage
No further work as been completed on the website.
At last meeting we assigned individual tasks to be completed for the second draft of the report.
