This week, I spent most of my time meeting with our team and TA’s to refine our project’s scope.\u00a0 We transitioned from two disjoint projects involving a custom RFID poker chip tracker and card imager to a single deliverable: a playing card holder that images and classifies playing cards as they are retrieved by the dealer.\u00a0 We framed the project such that there are clear individual contributions from each member.\u00a0 I will focus primarily on building the imaging system.<\/p>\n
Before our design review, I need to quantify the optical and electrical requirements for a camera.\u00a0 We require a camera whose optics provide reasonable resolution photos of the suit and rank within close proximity.\u00a0 We want to avoid fisheye projections that add non-linear transformations to the images; that would make the classifiers more difficult to train.\u00a0 Secondly, I need to determine a lower bound on the framerate based on how fast cards are dealt.\u00a0 Finally, we will tend towards cameras with stable linux drivers.<\/p>\n
Before our design review, I will also plan the lighting more concretely.\u00a0 Perhaps we could image a playing card under different color illumination to provide higher-contrast images for different playing cards.\u00a0 As we narrow the scope of the project, we will solve these design questions so Ethan has time to add these hardware changes.<\/p>\n
Our group decided to add a hardware switch that triggers when the dealer moves a card over the camera.\u00a0 This will avoid the unnecessary complexity of having the camera determine when a card is being dealt.<\/p>\n
We are on schedule to complete our proposal in time, and I will solidify the details above in the coming week.<\/p>\n","protected":false},"excerpt":{"rendered":"
