ASTM E 2938 : 2015 : R2023

1.1This standard describes a quantitative test method for evaluating the range measurement performance of laser-based, scanning, time-of-flight, 3D imaging systems in the medium range. The term “medium range” refers to systems that are capable of operating within at least a portion of ranges from 2 to 150 m. The term “time-of-flight systems” includes phase-based, pulsed, and chirped systems. The word “standard” in this document refers to a documentary standard as per Terminology E284. This test method only applies to 3D imaging systems that are capable of producing a point cloud representation of a measured target.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. SI units are used for all calculations and results in this standard.

1.3The method described in this standard is not intended to replace more in-depth methods used for instrument calibration or compensation, and specific measurement applications may require other tests and analyses.

1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
