Instead of scattering a bunch of scanning dots all over large surfaces, would placing a taped grid on the surface?
I spent part of my misspent youth pounding tin in autobody repair shops and am very good at following contours with masking tape and laying out reasonably square grids on things. Back before 3D modeling for airflow studies, we used to lay out grids on a vehicle and tape short pieces of yarn on the grid intersections. Then drive the vehicle while filming it from an adjacent chase vehicle. Where the yarn was bouncing around the air flow was turbulent, and where it was stuck to the car you had smooth laminar flow. Add some modeling clay and do it again to see if that smoothed it out.
Pulling a dozen or so runs of tape off a surface when I’m done with the scan would take only a few minutes, and would probably be quicker than removing a bunch of scanner dots.
