I'm setting up a viture luma to do something like this as well as have a HUD like interface for task tracking, like you'd have in video games. That said I'm taping the camera looking thing and I'm just going to use my phone when I need to take pictures or video. I'm setting it up where I could just transfer needed data directly whenever possible to avoid needing to use my phone camera. Most likely if i do use photos, it will be more of a photo journal than recording everything I see. This is mostly to try to keep others comfort and privacy in mind even though it would be stored locally on a raspberry pi.
