本文件规定了确定和评估地面激光扫描仪及其辅助设备用于建筑、土木工程和测量时的精度（重复性）的现场程序。这些测试主要用于现场验证特定仪器是否适合当前任务，并满足其他标准的要求。它们并不是作为验收测试或性能评估而提出的，本质上更全面。 本文件可被视为评估测量不确定度（更具体地说是被测量物）过程中的第一步。

This document specifies field procedures for determining and evaluating the precision (repeatability) of terrestrial laser scanners and their ancillary equipment when used in building, civil engineering and surveying measurements. Primarily, these tests are intended to be field verifications of the suitability of a particular instrument for the immediate task at hand, and to satisfy the requirements of other standards. They are not proposed as tests for acceptance or performance evaluations that are more comprehensive in nature. This document can be thought of as one of the first steps in the process of evaluating the uncertainty of measurements (more specifically of measurands).
