I'm trying to build a portable 3d scanner booth. My current plan is to have 4 Raspberry Pi 4Bs each with the 75 degree fov camera on one vertical column and have 6 of these columns arranged in a hexagon. The booth would likely only need to be powered on in periods of around half an hour multiple times a day but preferably the power source could last a total of 4 runs or 2 hours a day.
I have a network switch (Aruba S2500 48 POE) that I am trying to set up to both power the Pis with the POE hat and transfer data to a central laptop or another Pi4B. I figured this would make everything simpler having only one wire going to each pi and one power cable to the switch, as well as reliably getting the cameras to take a picture at the exact same moment in time to produce the best photogrammetry results.
However, I also am trying to figure out a second way of making the scanner without the network switch and having the Pis communicate over Bluetooth instead. This method would require me to power each pi individually or through some network of power cables. I've seen forum posts and videos about powering multiple pics but they seem to all be attached to a wall outlet. I am pretty new to any terminology involving power supplies or electrician work, what would be the best way to provide power to the pis for my use case?
I've seen people use pis for 3d scanner booths before, but no one has provided any documentation for the specifics on their setups so I'm mostly going into this project blind.
