avatar 4. 3D scanning batgirl

My task was to 3d scan an action figure. So here is the documentation of my failure to capture a Batgirl action figure.

First I put the figure on a revolving disk so I can get consistent 360 degree views of the figure. Then I put a green wall to have a strong contrast to the figure to mask the background out. To get enough light, I put two led lights for the wall, and two led lights for the figure. I set the settings as manual - large f stop for a deep depth of field, short shutter speed, low ISO, and manual focus. 

Here is my set up.

This is my first trial, which is a failure. Photoscan, a software for rendering a model from a series of 360 views of photos, aligned the photos chunk in one place.

It only rendered the upper body part and the head.

I thought it would work better if I take the Batgirl's cape off. I took the whole new set of photos and aligned in the Photoscan again. It somehow aligned in a weird shape instead of aligning in a ring of 360 views.

I deleted a bunch of photos stuck in the left side and only rendered the half ring of 180 views. Still not a pleasing result.

I took another set of photos again and all the photos got aligned in a half ring..

I took more sets of photos and finally got this result- 360 views of the model in a ring!

This is the final model screen-captured in Photoscan software.   I think the major reason of this series of failure is that the model's texture is too shiny and that the lights are reflected too much on the figure's body. When the highlights of the object change every time I rotate it, the software wouldn't be able to recognize the figure in different pictures as one same object. Next time, I want to try to 3d scan a model with a more detailed and less shiny texture.
