I haven’t done any modelling myself, but if I ever start, I’ll probably try openscad. Lego are fairly uniform, so I would wonder if more traditional machine vision techniques would work.
For machine vision, I was thinking of using multiple cameras and then just stitching the images together and using that as the input. That way it gets images of the bricks from multiple angles, which when combined with bright lighting from LED strips should make it easier to identify.
I have basically no experience with any machine vision, I’ve done some edge/color detection once, but my intuition says that sounds like a plan. Because you have a pretty unique feature for each brick, its number of studs and size of cavity on the bottom, you might not need as full a picture of each brick as you might think. That’s pure speculation though. Have fun with the project.
