3D Scanner

spline scan

SplineScan is a cross platform 3D scanning solution. While the target object is rotating on a motion controlled turntable a laser is projected on it. A camera collects images of each step of the rotation. Using simple trig the individual frames’ line data can then be used to construct a 3D model. Andrew Lewis is in the process of porting the model generator to C from VB, but it can already be run in Ubuntu using WINE. If all goes well he will be doing a live demo at LUGRadio Live with detailed source to follow soon after. He expects the final scanner to only cost approx. $90.  Sounds like a lot of  fun. Thanks for sending it in Andrew.

  1. Strangely, I was just wondering this morning how you could make a DIY 3D scanner. I got stuck on how to measure the depth of an object, but apparently that problem has been solved.

  2. amazing. can anyone possibly imagine the effect 3d scanning will have on our lives; of computers sharing the same 3d space as we do? anyway, i need some reference for a paper i’m writing on the subject. thanx

  3. Re: not very much res – actually, the raw point resolution is less than 1mm – the model you are looking at was roughly 2″ high. The reason the pictures look dodgy is because my triangulation algorithm was broken, and the scan only took a couple of hundred samples. Take a look at the new python code and try the pointcloud data out in opendx – I think you might be plesantly surprised :-)
