This week I worked on setting up the environment and the end to end software architecture for the system. We have a github repository where I have created mock modules for each function and step of our system. I also worked on designing what our database would look like and what data our system would need to communicate between all the modules. After working on this, I am slightly concerned about the camera inputs to the system since we need several cameras, and I am not sure how many data streams the system can support, especially since our current system needs 2 cameras per checkout line. In the next week, I hope to work on the computer vision component of identifying how many people/items exist in a line in a given camera feed.
