Training Manual for Trainers: Photogrammetry for 3D Modeling | CULTUURCONNECT

Objective
Provide trainers with a practical, step-by-step guide to teach participants how to use photogrammetry techniques to capture real world objects for 3D models. 

 

  1. Preparation (approx. 15 minutes)
  • Objective: Set up a functional, safe environment for scanning and post-processing 
  • Steps: 
  1. Set up workspace with good, diffused lighting (avoid harsh shadows). 
  1. Prepare hardware and equipment: iPhone or DSLR cameras, tripods, etc. 
  1. Check software installations (e.g., Reality Capture). 
  1. Prepare example objects with varied textures (avoid shiny or transparent surfaces). 

Checklist: 

  • Camera batteries charged and memory cleared 
  • Photogrammetry software installed and tested 
  • Sample object(s) ready for scanning 
  • SD cards, card readers, and cables available 

 

  1. Introduction to Photogrammetry (approx. 15 minutes)
  • Objective: Build an understanding of photogrammetry and its applications. 
  • Steps: 
  1. Define photogrammetry: capturing 3D models from 2D images. 
  1. Show inspiring examples from performance, stage design, or installation art. 
  1. Explain basic principles: camera overlap, consistency, and coverage. 

Trainer Tip: Use visuals (before/after models) to make the concept instantly clear. 

 

  1. Hands-On Scanning Practice (approx. 30 minutes)
  • Objective: Give participants direct experience in capturing an object for a photogrammetry. 
  • Steps: 
  1. Demonstrate camera angles: move in a circle, keep focus and distance consistent. 
  1. Emphasize 60–80% overlap between images. 
  1. Have participants practice photographing an object or small scene. 
  1. Review image sets for coverage and quality. 

Trainer Tip: Encourage experimentation but emphasize coverage, image consistency and data quality. 

 

  1. Post-Processing & Model Generation (approx. 20 minutes)
  • Objective: Teach participants how to create a 3D model from their photo set using Reality Capture. 
  • Steps: 
  1. Open RealityCapture and import the image set. 
  1. Align Images the images to generate a point cloud. 
  1. Create a 3D mesh of the object. 
  1. Apply image-based surface detail. 
  1. Export the model in a usable format (.obj, .fbx). 

Trainer Tip: Use a pre-prepared photo set if alignment or reconstruction fails during the session. 

 

  1. Wrap-Up and Feedback (approx. 10 minutes)
  • Objective: Recap learning, clarify doubts, and prepare for independent use. 
  • Steps: 
  1. Summarize the photogrammetry workflow. 
  1. Share additional learning materials and video tutorials. 
  1. Gather feedback and suggest ways to apply photogrammetry in personal projects. 

 

Post-Training Follow Up 

  • Access to sample datasets and cheat sheets for home practice 
  • Troubleshooting tips (e.g., blurry images, bad alignment) 
  • Community groups for photogrammetry sharing 

Trainer Tip: Encourage experimentation with different object types and environments to build skill.
