ASTM E3125 PDF

1.1 This test method covers the performance evaluation of laser-based, scanning, time-of-flight, single-detector 3D imaging systems in the medium-range and provides a basis for comparisons among such systems. This standard best applies to spherical coordinate 3D imaging systems that are capable of producing a point cloud representation of an object of interest. In particular, this standard establishes requirements and test procedures for evaluating the derived-point to derived-point distance measurement performance throughout the work volume of these systems. Although the tests described in this standard may be used for non-spherical coordinate 3D imaging systems, the test method may not necessarily be sensitive to the error sources within those instruments.
