Using photogrammetry to capture data in the round


video

With DigitalFossil 2012 in a few week's time it seemed appropriate to post some of the work I've been doing recently. Part of this has focussed on creating a workflow for capturing data a full 360-degrees with minimal loss of data, which leads to holes in the mesh and distortions. By way of an illustration here is an animation of an early 360 capture of the cast of a Conchoraptor sp. skull, showing the wireframe, mesh and textured model. It loops seamlessly for your viewing pleasure.

  1. Very cool. I am biased about the subject and its connection to photogrammetry, of course, but that's me.

  2. I received photos of the Euparkeria holotype skull a short time ago from R. Sookias. He'd wanted to document it from all sides, with no intent of photogrammetry. I gave them to Photoscan and got a perfect 360° model with no hassle :)

  3. I'd like to see that Heinrich. Did the background separate out OK?
