Reality Capture & Scan-to-BIM
Measuring the real world into data you can build on — why capture reality (the world measured as point clouds and models, the foundation of good work on existing buildings and sites), measurement and survey fundamentals (accuracy, precision, error, coordinate systems, control and registration), photogrammetry, laser scanning and LiDAR (terrestrial, mobile/SLAM, drone and phone), the neural turn (NeRF and Gaussian splatting), point clouds and meshes, scan-to-BIM (modelling from the cloud, levels of accuracy and detail, automation), workflows and tools, applications across the lifecycle (survey/renovation/heritage, coordination, construction QA, digital twins), quality/accuracy/professional practice, and practice and the future. Rigorous and honest (captured data is measurement with real limits, not ground truth), for architects, interior designers and students — deferring survey-grade accuracy, georeferencing, legal/boundary surveys, structural monitoring and any binding deliverable to licensed surveyors, verified equipment specs and the governing rules (incl. Survey of India and the Drone Rules), and treating accuracy, range and cost figures as illustrative.

Module 0 · Why Capture Reality0.1 · The World, Measured
Reality capture turns the physical world — a site, a building, a room — into accurate, measurable 3D data: point clouds, meshes and models. This lesson frames why captured existing conditions are the foundation of good work, surveys the methods, and sets up the course honestly.

OpenWhat this course covers
The through-line- 1Measurement & Survey Fundamentals. The bedrock: from the tape measure to the point cloud, accuracy versus precision and the nature of error, coordinate systems and georeferencing, and control, registration and ground truth.
- 2Photogrammetry. Measuring from photographs: how photogrammetry works, capturing good photos, from images to 3D (structure-from-motion and multi-view stereo), and drone and aerial photogrammetry.
- 3Laser Scanning & LiDAR. Measuring with light: how laser scanning works, terrestrial laser scanners, mobile/handheld/SLAM scanning, and LiDAR on drones and phones.
- 4Neural Capture: NeRF & Gaussian Splatting. The new frontier: the neural turn in capture, neural radiance fields (NeRF), 3D Gaussian splatting, and where neural capture fits (and where it does not) for measurement.
