3D Laser Scanning
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.
What Is a Mesh Model? Point Cloud vs. Mesh
Jul 5
A mesh turns a point cloud into a continuous surface. The difference between the two, and when each is the right deliverable. ...
Understanding Scan Resolution & Point Density
Jul 5
Scan resolution and point density control how much detail a laser scan captures and how large the files get. How to choose the right setting. ...
Terrestrial vs. Handheld vs. Mobile Laser Scanning
Jul 5
Terrestrial, handheld and mobile laser scanners trade accuracy for speed and access. When each one is the right choice. ...
What Is Registration in 3D Laser Scanning?
Jul 5
Registration aligns individual laser scans into one accurate point cloud. It is the step that decides the documented accuracy of everything built from the scan. ...
Point Cloud File Formats Explained: RCP, E57, LAS, PTS and More
Jul 5
RCP, E57, LAS, PTS and PTX: what each point cloud format is, which software reads it, and how to pick the right deliverable for your workflow. ...
3D Laser Scanning vs. Photogrammetry vs. Drones: Which Is Right for Your Project?
Jul 5
Compare 3D laser scanning, photogrammetry, and drone surveys by accuracy, speed, and cost so you choose the right reality-capture method for your project. ...
What Is a Point Cloud? A Beginner’s Guide
Jul 5
What a point cloud is, how a 3D laser scanner creates one, and how architects, engineers, and owners turn it into drawings and BIM models. ...
