I like your project. I'm a SWE working on something completely different by day but tinkering with several other side projects, including this, https://github.com/ratsbane/panda-mcp/ (which is accelerating my computer vision learning rapidly)
I'm interested in your choice of the OAK cameras because I'm trying to select a camera model also. I started this with a simple USB webcam and added a PhotoNeo camera. I've just switched to RealSense and I've got a couple of ZED cameras on order but now I'm looking at the OAK-D and thinking that it makes a lot of sense to run a nn directly on the camera.
I started this over the summer when I was moving to a new house and wanted to document the family history behind some thing I own. It's turned out to be more useful than I thought and I've expanded the features as friends found it useful. A developer friend, who I used to work with, joined me and we're both working on it now. It does have a little revenue now but we are far from quitting our day jobs.
I'd really like any feedback from the HN community!
