After spending several hours working on the report and completing the ethics assignment (before the deadline got pushed back), I spent some more time working on the Theia iOS app. I am slowly learning how to navigate xcode, but managed to create and connect several scenes and I think I am close to having the basic flow of the app put together. The biggest hurdle I see coming up is figuring out how to receive information from the Raspberry Pi…
The start of this week was spent preparing the design review report, which was due on Monday. Since the design review presentation we have redesigned the sensor orientation on our wearable. To avoid complications regarding interference with multiple ultrasonic sensors, we decided to instead spend our budget on additional LIDAR sensors. We had been using the ultrasonic sensors because of their wider field of view, but if we get three LIDAR sensors and orient them all at slightly different angles…
DESIGN DOC DUE EARLY THIS WEEK The beginning of the week was focused on creating and proofing our design doc. I focused on writing up the System Design section and Wearable Design. I also worked on the Bill of materials and our updates Block Diagram (As seen below). I also design a draft of the mount that could accommodate 3 LiDar sensors at precise angles relative to each other (depicted below). The plan is to design this in Inventor-Pro and 3D print the…
This week I did a lot of work on the object recognition part, to really explore the capabilities of OpenCV and finalize our design for this part of the project. As a group we also spent a lot of time doing the design report. I decided that the best way to do fast object recognition for this project is based on the geometrical differences between the 3 different types of objects. In experimenting with online images, I found that edge…
