Topic: Getting good scans
Now that I started playing with this gadget, I need to figure out how to get some usable scans out of it. There are so many questions that I can't find the answers to.
I followed the instructions on calibration and I can now get the scanner to generate something that looks remotely like the object I'm scanning, but it really need a lot of work. So below are some of the first problems and questions I'd like to resolve.
1. Camera focus. Is there a way to focus the camera, manually or electronically? The object on the turntable is not in sharp focus, and when I look at the camera live feed I can't tell the difference between low res (640x480 and the higher resolution 1.9 or 5Mpixels)
2. There is an option to scan with either the left, the right or both lasers. What is the difference between the options. By default it wants to scan with the right laser.
I know I'm getting ahead of myself here, but we'll probably need some kind of "post scan" clean up instructions. The resulting scan has many open holes, and areas that just weren't "seen" by the laser. Additionally, the surface is extremely noisy, and has many errors. Even the little sample that was included with the software (a little Buddha statuette scan) suffers from this. How do we fix this?
I know that in the earlier thread in the "projects" forum, MeshLab was mentioned as the tool used to clean up the model. Instructions on how to do this would be very helpful here.
So without further ado, here are the the results of the first scan attempts, with all their warts:
This is a composite of what the camera sees at default resolution (1600x1200). Next to it is the test shot, with the Laser Threshold set to 5.
The next image is resulting scan PLY point cloud file, loaded in MeshLab. Notice all the missing parts. The only reason you can see recognizable features is because of the color texture map.
Last is the generates STL file loaded into NetFabb. No texture here, so the model is almost unrecognizable. The right side shows a closeup of the surface. Super jaggy and noisy.
Obviously were a long, long way from what we saw on the previews from Uriah. So we definitely need some guidance here.
