has anyone ever laser scanned a sailboat?
I'm thinking about doing this to my sailboat. I think it might take two setups for the exterior and with any worthwhile luck, a couple more from inside.
If anyone has ever done one, could I get a rough idea of cost(I have absolutely NO idea of possible costs) for the 3d points at about 2-4 inch intervals. I've already shot all the more critical points(toe rails, keel, bow, stern and such) with a total station.
Cool.
I would crank up the number of scans to at least 4 of the outside.
The resolution will affect the time. 1/4 resolution takes about 12 minutes a scan, full resolution takes about 2 hours a scan.
Deliverables? Cloud is easy, CAD model is time consuming.
I am looking at about $250 an hour for the scanning and about $125 an hour to process. Numbers are always in flux...
What are you thinking about? A scale model, done with a 3D printer?
I have to agree with this, but, I am thinking four on the outside is still small. Complexity governs on the inside. Time depends on the scanner used as well.

Scanned a boat that was dropped on its side while being lifted for maintenance with an HDS3000, when that was the newest scanner. They had the boat out of the water on stands. I want to say we took 6 scans for pre repair and another 6 scans months later for post construction. The marina that was doing the repair had marks on the sides of the boat where they wanted sections taken for the pre and post scans. They had to certify that the boat was symmetrical after the repair.
I've done it for several years using photogrammetry for the Naval Research Labs. The bulkhead profiles are all that are needed. Anything else is a waste of time since the surface is faired in between the bulkheads. For photogrammetry I use small Reflexite targets made with an office hole punch and I image them with an electronic flash. KISS works well.

LOL
I would say it always takes more scans than you think. I have been scanning several 17m RNLI Lifeboats and you have to do almost 3 scans at each location you do around the boat - 1 low/beneath, 1 at a mid height and 1 on top - I think I have been using a Leica C10 and undertaking an average of 70 scans per boat to ensure as complete coverage as possible.

Boy, that brings new meaning to the term "Marine Surveyor"!
Interesting.
What made them think it was symmetrical before the accident?
Boats are supposed to be but considering the vagaries of building them, I'm sure many aren't exactly symmetrical.
