    Abstract - (Show below) - (Hide below)

    CONTAINED IN VOL. 10.04, 2015 Specifies a quantitative test method for evaluating the range measurement performance of laser-based, scanning, time-of-flight, 3D imaging systems in the medium range.

    Scope - (Show below) - (Hide below)

    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.

    1.1.1As defined in Terminology E2544, a range is the distance measured from the origin of a 3D imaging system to a point in space. This range is often referred to as an absolute range. However, since the origin of many 3D imaging systems is either unknown or not readily measurable, a test method for absolute range performance is not feasible for these systems. Therefore, in this test method, the range is taken to be the distance between two points in space on a line that passes through the origin of the 3D imaging system. Although the error in the calculated distance between these two points is a relative-range error, in this test method when the term range error is used it refers to the relative-range error. This test method cannot be used to quantify the constant offset error component of the range error.

    1.1.2This test method recommends that the first point be at the manufacturer-specified target 1 range and requires that the second target be on the same side of the instrument under test (IUT) as the first target. Specification of target 1 range by the manufacturer minimizes the contribution to the relative range measurement error from the target 1 range measurement.

    1.1.3This test method may be used once to evaluate the IUT for a given set of conditions or it may be used multiple times to better assess the performance of the IUT for various conditions (for example, additional ranges, various reflectances, environmental conditions).

    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 and health practices and determine the applicability of regulatory limitations prior to use.

    Some aspects of the safe use of 3D Imaging Systems are discussed in Practice ASTM E2641.
