3D Scan with Camera

Hi,

Everyone knows the possibility. i tested arround a bit with agisoft photoscan.

These are the results which i think are great. Sure because its natural forms but these are most difficult to build.

Thanks for posting this - I didn't know the results could be so good - and with 360 degree coverage. Can you explain a little about your procedure?

Ah, definitely great results. Just makes you imagine the possibilities 10 years into the future :P

Agisoft is great. I've been using it for a year now (standard version is plenty already and very affordable), it's very easy to use and gives excellent results on matte textured objects.

You need a rather beefy machine with lots of ram if you want to cover a large area with lots of photos (the pro version is firstly made for aerial photogrammetry) but otherwise it's a great tool. The autocalibration is awsome by itself and the new pro version allows in-motion 3D capture... Can't test it, but some have :

yes. first you have to pick an object which is matte and good for that process. then you take 10-40 photos of it from different angles that the photos show the object from all directions you need or want. then you let agisoft calculate a pointcloud. then the geometry and finally the texture. i calculated these objects with 40GHz Dual Xeon with 48GB RAM. all objects took about 15 hours. then you can export them in FBX OBJ and other formats to your 3d app and render it. its really simple. settings are simple too. these objects are calculated with "ultra high" settings.

Hi,

"40GHz Dual Xeon with 48GB RAM. all objects took about 15 hours"

Wow that's much.
U can try Autodesk 123d-catch: http://www.123dapp.com/catch
This will do the same, but your model is calculated in the cloud, so even with a small laptop you can play around, about 15 minutes(not hours) to calculate a model.

Ciao
Andreas

thx i know 123D! its nice.

here i tested a couch and a carpet. generic forms are better because they donīt need to be 100% accurate.

Myself and some friends have done a bunch of tests with agisoft and 123dcatch, and agisoft tends to give nicer results. Plus for professional work not having to send your photos off to someone else is a must

yes youre right. 123d is more fun app. what kind of objects have you successfully "scanned" with agisoft?
 
  12 December 2012
One super quick "hack" way to get better results out of agisoft photoscan is to apply a random high contrast blotchy pattern of paint onto the object. This gives the software more features to lock onto, so the mesh will end up much more accurate and detailed..
