- Introduction
Standard Overview and Technology Evolution
ASTM E2544-24 is the core terminology standard for 3D imaging systems. First published in 2007, the 2024 revision integrates 12 relevant standards from six international organizations, including ISO and ASME. This standard resolves conceptual confusion in cross-disciplinary communication by unifying terminology for devices such as lidar and structured light systems.
Analysis of Core Terms
Terminology Definition Technical Relevance 3D Imaging System A measurement system that generates a three-dimensional representation of an object in a non-contact manner Including terrestrial laser scanners, structured light systems, etc. Measurement Accuracy The degree of closeness between the measurement result and the true value Consistent with ISO/VIM 3.5 definition Beam Diameter (dσ) The extended range of laser beam irradiance distribution Second-moment calculation method based on ISO 11146-1
Comparison of key technical indicators
Chapter 3.1 of the standard integrates 21 basic metrological terms from different organizations, including:
- Five terms provide both ASTM and ISO definitions
- Specially note the qualitative/quantitative distinction between "accuracy" and "precision"
- Three new system definitions, including Flash LiDAR
Implementation recommendations
- Give priority to the 23 specific terms developed specifically for 3D imaging in Chapter 3.2 of the standard
- Key parameters such as "beam spread ratio (M²)" should be clearly marked in the system specification
- Avoid using non-recommended terms such as "spot size"
