This week I’m focusing on computer vision part, trying to make design decisions to maximize the accuracy of computer vision.
Claire and I put the board and the LEDs together and here’s what it looks like. LEDs line up with the grid intersections.
The led light is diffused by frosted acrylic and one design that needs to be changed or actually added is that since the led light makes a bright dot on the piece, it will affect the cv accuracy as it “covers” the characters on the pieces, or i will need to take a whole lot pictures for yolox learning. To tackle this, we will probably add a step of turning off the leds before cv part runs each time. This will make cv easier and more accurate.
I also drew CAD for the layer under the board, the one for attaching the leds. Since there a 9-10 led stripes, taping them to the back of the board has very low robustness and will require us to fix the position all the time. So i will laser cut a plywood stripes layer for the leds to be stuck on.
I will also need to design the whole board box, as we need to fix the place for all the hardware for transportation, and I will need the design to be some what modularized to make fixing things easy.
Next week I will be taking all the photos for yolox board state recognition, and designing the box. I am on schedule and the small designs added such as the turn led off thing shouldn’t add too much workload to affect schedule.
