SDK for 3-D reconstruction of objects

Hi,

I'm using an Intel RealSense 415d with Intel's librealsense SDK Python Wrapper.

I was wondering if you had any modules for automatic 3-D reconstruction of objects. I am looking to align depth frames that have been obtained from multiple viewpoints to generate one ply file for a complete 360-degree view of the object (something on the lines of photogrammetry). If you don't, I would appreciate it if you could point me to some other existing modules that can help me achieve my final objective.

Intel did something similar with four hardware-synced D435s at their tech shack at the Sundance Festival in January 2018. The technique is called Volumetric Capture. With 4 cameras they could capture 180 degrees. In their article about the demo, they suggested using 8 or more cameras for a 360 degree capture, adding more cameras until all the holes in the data were filled.

A company called Jaunt also recently introduced a six-camera 360 degree volumetric capture method that seems to use D415s.

You can read Intel's white paper on multi-camera setups and hardware syncing at the link below:
