Scan processing question

Post by shocktube » 11 May 2018, 20:26

We're looking to purchase a structured light scanner for a couple of projects that will involve scanning about 200 shoebox sized items. There needs to be texture and color in the final model. My question is since some parts of these items will reflect light and not be picked up, what is the method people use to "rebuild" those parts of the scan? Is it common to use multiple scanning techniques or multiple software programs? Also, what's the job title/skill set of the person we would have to pull in to finish the scans? The budget for the equipment doesn't allow for anything more than about $7,000. We're looking at an EinScan-Pro+ right now because the price and resolution are in the ballpark of what we need. Thanks.

Can you coat the shiny parts of the subject for scanning? (Water soluble coatings).

If you are looking for a hand held, have a look at the Peel (https://peel-3d.com/). To me it looks like a much better scanner than the EinScan.

Thanks, I'll look at the peel. Spraying any surfaces won't solve our problem completely because we'll still need someone to recreate those surfaces. We need the scanned items to have the original look. Gray surfaces won't work for us.

Photogrammetry is another approach.

Scanning reflective surfaces is going to be a problem. If it has some color you will need to at least dull it. One option that is more work but could help, is recreating or editing and applying your texture map after the scan. If you really need the texture for presentation then you are probably going to have to do the anyway. Again, outside of $30k scanners, the best way I've seen for capturing texture is the use of a DSLR in conjunction with the scanner and then editing and remapping the texture. There are a free apps that will do this but of course the best and easiest ones are big $. Remember the scanner is only part of the equation. And for what you want to do it may be a smaller part than you think.
