Last week, I finally was able to use the laser scanner to create images of the wound models.
The Artec Space Spider 3D Scanner is a handheld device that captures the details and colors of objects with amazing accuracy. It uses blue light technology to create geometrically sound models in the computer program, Artec Studio 11.
To capture the full object, I had to rotate the scanner around the whole object. This is how it looked in the computer program.
The front view shows a model with smooth fusion and increased brightness.
As you can see, the sideview has a few discrepancies. This is because of the glare that results from scanning a reflective object.
One of the problems that I will tackle this week is finding ways to improve the lighting for the scan. Usually, engineers use powder to reduce the shine of an object. However, since I will potentially be using the scanner on real wounds (following regulatory/hospital approval), powders/chemicals are not a strong option to reduce the glare off blood.
See you on my next post!

Hey Asfia. This is really neat stuff. It is really interesting how you can recreate wounds using a laser scanner! I was wondering, are you creating the wounds as physical objects first or is it on the computer program first? And if it is on a computer program, how does it turn into a physical replica of a wound?
ReplyDeleteThe wounds are going to be physical objects first. For now, I am using models I created on a suture pad. Later, I will potentially be scanning wound on actual patients.
DeleteIf I did need a physical manifestation of what is in the computer program, one option is 3D printing. This would produce an exact replica of what the model looks like on the computer, including coloring and texture.
Hey Asfia, this seems incredibly interesting. Is the glare resultant of the light from the scanner itself or overhead lights in the room, for example would turning off the white room lights help to reduce the glare? Thanks, good luck with your project!
ReplyDeleteI was actually looking at this yesterday. There is an option to turn off the blue light that flashes from the scanner. I will do some new scans to see if that will help. Thanks for pointing it out!
