Calibrate size of 3D Scanned Photogrammetry Mesh in Blender

In this video, you'll learn how to scale photogrammetry 3D meshes accurately in Blender. Photogrammetry converts 2D images into detailed 3D models, but lacks real-world scale information. The tutorial walks through essential techniques for adjusting scale using measurement devices like rulers and cubes. You'll discover how to align 3D objects, calibrate dimensions, and ensure precision when modeling objects such as an apple. By the end, you'll understand how to scale your photogrammetry models for use in various 3D projects, making sure they fit real-world dimensions perfectly. 00:00 - Introduction to photogrammetry and 3D mesh creation 00:16 - Issue with scale in photogrammetry models 00:32 - Using tape measures for scale calibration 00:51 - Aligning axes in Blender (x, y, z) 01:17 - Creating a cube and adjusting dimensions 01:31 - Setting cube size for accurate scaling 02:17 - Positioning and scaling the 3D mesh in Blender 03:03 - Final scale adjustments for real-world accuracy 03:50 - Calibrating with rulers and cubes 04:35 - Double-checking accuracy and common issues 05:08 - Importance of multiple measurement points 05:32 - Wrapping up: using scaled photogrammetry models in 3D projects This tutorial ensures your photogrammetry meshes are ready for real-world application in 3D modeling, improving your workflow and accuracy.
