Celine:
This week I finished setting up OpenCV on my laptop and was able to run OpenCV with both python and C++ programs. In addition to the setup, I further researched some methods we have to use to perform image processing on document images: document alignment using edge detection, which can be done with imutils in OpenCV, and image binarization by reading the image as grayscale then applying a threshold. There is the problem of segmenting apart the two pages in the image, so I am thinking to possibly just sum the image into a histogram to do this. For the gear replication, we were not able to work on it this week, but we have decided that we will laser cut the gear instead of 3D printing it, as it will be faster and produce a smoother gear. Finally, I wrote up a draft spreadsheet detailing what needs to be done in each component of the project.
This coming week, I will be working on the design presentation with Indu and Effie. I will also implement the above mentioned image processing methods on some experimental data. I will also get the gear designed and cut with Indu.
Effie:
This week I (hopefully) finalized our parts list and ordered the motors, servo, pi + sd card, pi hat to connect to motors and extensions, and wheels and mapped out how we will connect all the pins. While we await the parts arrival next week we will work on the design proposal, and do research on how to operate the motors with respective drivers and code up some pwm logic – so we’ll be ready to hit the ground running when they come in.
Indu:
This week we got our initial parts, which were mainly the Arducam, gear, and conveyor chain. After heavily analyzing all the parts we received on Monday with Celine, we worked on further flushing out what each part of our block diagram will consist of and involve.
This week I worked with Effie on further planning out how all the other parts will be working together, such as the Raspberry Pi and motors for our wheel and conveyor chain. We also decided to buy a servo motor as a backup method of turning the page if the conveyor chain method proves to not work the way we thought. This involved working with Effie to make sure each part we ordered can be integrated with all the others. It also involved me working on a rough sketch of what the whole design should look like to test the page turning part of the project. I want to make sure that the dimensions of the stand and conveyor chain will be practical for a binder, as that is what we want to test with first.
This coming week I will be working with my team on the design presentation. I will also be working with Celine on designing and cutting the other gear for the conveyor chain part of the design. If we receive our parts this coming week, then hopefully I will be able to build a prototype of the page-turning device.
