Why Accuracy Matters in 3D LiDAR Scanning
3D LiDAR scanning is now widely used across engineering, fabrication, and building projects — but not all scan data is created equal.
While many tools can generate dense point clouds, the real question for engineers and asset owners is whether those measurements are accurate, repeatable, and defensible. This is where AS ISO 5725 – Accuracy and Precision of Measurement becomes highly relevant.
AS ISO 5725 is not a scanning standard in itself. Instead, it defines the principles used to evaluate whether a measurement system can be trusted. When applied to 3D LiDAR scanning, it highlights the importance of calibration, measurement uncertainty, and the difference between data that looks correct and data that actually is correct.
In practical terms, poor measurement control during scanning can lead to downstream issues such as:
Fabricated steel that does not fit on site
Misaligned bolt holes and interfaces
Incorrect assumptions about clearances
Delays during engineering review or certification
These issues are often discovered late in a project, when changes are most costly.
We’ve published a detailed technical article explaining how AS ISO 5725 applies to 3D LiDAR scanning, what accuracy and precision really mean, and what can go wrong when scanning tools are not properly calibrated.
