Background:
i am a software engineer, and have made a few iot pcb prototypes and integrated a lot of sensors and embedded devices.
Not familiar with stepper motors.
current project:
I wanted to buy/make motorized 3d scanner/camera that can work as a 3d room scanner. I was thinking having a camera on a tripod is better than hand holding the camera in terms of motion blur/focus ..etc. This is to create multiple image+depth information from different locations around the room to create a point cloud or 3d model, that requires some but limited manual tweaking to finally produce a decent and somewhat detailed 3d model of a room.
from the available and somewhat affordable options I saw were 3d cameras with depth information, as i saw decent results from app on iphone 12 plus depth or tof sensor, so i think i should be able to make a program that does similar or more accurate 3d scanning.
I am going to get this to test,
orbbec Astra+ or Astra plus. similar to intel realsense but it seems people are suggesting that intel is abandoning realsense and I saw multiple products EOL-ed.

I was thinking of placing that camera on a motorized pan tilt sensor,
something like,
https://www.amazon.com/YT-260-Remote-Control-Motorized-Extreme/dp/B07NKVZCQZ
which seems fine, but I wanted to control the pan tilt myself, so i can program the movement, and time when the photos are taken in an automated way, so i was thinking maybe I can get a stepper motor or two like,
- NEMA-17 https://www.adafruit.com/product/324
- some hardware and brackets?
- some motor driver or shield for Arduino or raspberry pi?
- some adapters to go from a tripod mount to pan tilt device to the camera?
but i am not familiar with motors and the components needed to make a decent pan tilt kit/device. Advise is appreciated.
Maybe something like this,
Mini Pan-Tilt Kit - Assembled with Micro Servos
https://www.adafruit.com/product/1967
but preferably in metal or aluminum and maybe the rotation to be on axis if possible instead of off axis or above axis, unless something like the link is enough if i change the motors with stepper motors. i have used these hobby servos in the past and I know that they don't really move in accurate "steps", which is not a strict requirement for me, but i think more accurate movement might lead to less corrections and processing in my application.
alternative options to have motorized 3d scanning solutions or components are welcome.
