Photogrammetry

Photogrammetry is the process of stitching multiple 2D shots into a 3D model. Using this method, a model in the real life can turn into a 3D-printable model! 

I first discovered photogrammetry through Josef Prusa’s excellent video on the subject. He carefully runs through the whole process of taking photos of a model, to stitching them together, to editing the mode, and finally to 3D print them. For detail instructions on photogrammetry, I highly recommend Prusa’s videos.

This ceramic sheep, Derpy was chosen as the subject for a few reasons. Firstly, in order to create a well-defined 3D model using Meshroom, the pictures taken need to be free of reflection and glare. The matte ceramic finish on this sheep makes taking good shots easier. Secondly, the sheep is very textured and distinct, making the final 3D-printed model distinct. Thirdly, Derpy looks cute.

For photogrammetry, software such as Meshroom, can stitch 2D photos together to create a 3D model. I took more than 100 photos of Derpy just to be on the safe side, but around 50 photos should work just fine.

For editing the 3D model, Blender can be used to smoothen the few jagged edges from the resulting 3D model created by Meshroom. I recommend you watch this Youtube video on how to edit and clean up your Meshroom model using Blender by Crompwell. For Derpy though, I mostly left the textured details alone.

The 3D model is converted to an STL file and sliced using CURA to create the g-code for 3D printing. The final result manages to capture a surprising amount of detail from the original ceramic sheep.
