- LiDAR
- Light Detection and Ranging — a laser sensor that measures distance by timing reflected light pulses. It produces precise 3D depth data and is what enables outdoor capture and sub-centimeter measurement accuracy.
- Photogrammetry
- Reconstructing 3D geometry from overlapping 2D photographs. Non-LiDAR scanners like the Matterport Pro 2 rely on it — it works well indoors but struggles outdoors and in large open spaces.
- Point cloud
- The set of millions of 3D coordinate points a scanner captures to represent the surfaces of a space. It is the raw geometry that floor plans, measurements, and 3D models are built from.
- ANSI/BOMA
- Published standards for measuring floor area — ANSI Z765 for residential, BOMA for commercial. iGUIDE's automated floor plans are measured to these standards, which is why agents and appraisers trust them.
- Dual-height (dual-pass) capture
- Scanning each tripod position twice at two different heights to improve LiDAR coverage and floor-plan accuracy. The Giraffe360 Pro Camera automates this with a motorized tripod.
- Digital twin
- A dimensionally accurate, navigable 3D replica of a real-world space — the end deliverable of most 3D scanning workflows.
