Laser Scanning Technology

The hardware, formats and field methods behind reality capture. Terrestrial laser scanners, LiDAR, registration and control, scan resolution and point density, georeferencing, occlusion, and the file formats that move data between platforms. These articles are written for people specifying or buying scanning work rather than operating the equipment — what accuracy claims actually mean, how scanner choice affects a deliverable, and which technical decisions on site determine whether the resulting data is usable downstream.

Terrestrial vs. Handheld vs. Mobile Laser Scanning
