There are a few different ways to automatically mask backgrounds when making a 3D model using photogrammetry, but I’ve struggled to find a method that worked for what I was doing. Photoshop released a new AI feature to automatically select the subject of an image. This post explores how this tool can be used to mask unwanted background features when creating 3D models using photogrammetry. This is not a photogrammetry tutorial, and I assume a basic familarity with Metashape (formerly Photoscan), the software I use for photogrammetry.

This tutorial demonstrates how to accurately size a 3D model using the open source software Blender.
I was recently able to photograph the Pilling Figurines and process the images into 3D models using Agisoft Photoscan.
