Good to know how something like this might work in the real world. I will be working on a similar project in the coming months. Do you know how reality capture would work indoors, i.e., where a truck can’t go?

There are different devices for scanning indoors. There are handhelds, backpacks, total stations with laser scanners, and survey grade scanners on tripods. Some have on-board GPS. All of these have some way to register to control points. If you start outside then you can have real world coordinates inside so you can relate inside facilities to outside infrastructure. Alternatively if you are only interested in inside, then you can simply use a relative (0,0) coordinate system. For example, the Leica BLK360 allows you to specify the origin of a local (0,0) coordinate system after a scan. Leica's Cyclone and Register360 can be used to register to control points. I would be interested in knowing more about what you plan to scan indoors.
