I am a hobby user and have a Mavic 2 zoom. I am using Maven for the photogrammetry. What suggestions do you have for free software to process 3d results.?This is not for any commercial use. In fact I am waiting for the rain to stop and the wind...

Reality Capture, Capturing Reality
Between the two should keep you pretty busy.
For image acquisition someone else will chime in. I only use Enterprise drones where this is built-in. With the Mavic you will have to find something.
