Here’s an example of the reconstruction of a skull from 2D photographs using the open source software “Meshroom” from AliceVision. It was done by placing the skull on a simple kitchen one-level lazy susan and rotating it in front of the camera. Shots were taken from three heights. It worked surprisingly well. The only real problem I have is registering the mesh from the top with the mesh from the bottom.
Here’s the mesh in Blender.
Here’s a screenshot from Meshroom showing the positioning of the camera for the photographs:
