I’ve been working on scanning large fiberglass fairings from an airplane. My plan is to use the scan to create moulds on my CNC machine, using the scans as a reference to begin the modeling in Fusion 360. I’m using techniques I’ve learned on the forum, scanning small sections and stitching them together in Cloud Compare. After a frustrating start, I’m finally getting some results that I’m happy with. One thing I can’t figure out though, is why the markers appear as large bumps on my point clouds??
I’ve screen grabbed a mesh of one small scan, so it’s more apparent. The scan also shows the perfectly smooth surface of the fairing much rougher than it actually is, so perhaps it isn’t a surprise that the stickers look like big puckered vaccination scars!
Because this particular fairing has a mix of large blank surfaces and some finer details, I’ve covered it in markers, and I’m scanning with a mix of marker and feature.
@Cody that is normal , the black surface around the markers create the effect , unusually you should not close the holes when meshing in Revo Scan , especially if you are doing reverse engineering , and if you really need the holes to be closed you could do that in Revo Studio using the tanged space mode for closing holes .
But since you use it for reverse engineering anyway I would ignore it . And if you use black surfaces for that type of work please use spray , adding too high gain while scanning dark objects with markers will make the bumps even worse .
Thanks for the info! This particular part is grey, but high gloss. I don’t have any spray but I’ve been scanning with the gain turned all the way down, and keeping the scanner at a 45° angle to the surface to reduce glare - it seems to be working alright.
When I get this all scanned and stitched together I’m sure I’ll have more questions about smoothing out the mesh
@Cody when you working in Revo Studio , smooth the merged point cloud before meshing it , it will give you better results , the individual bumps need to be smoother manually in a 3D software of your choice , since you already captured it in your point cloud .
