标准范围

本文件描述了检查激光轮廓仪性能的方法，以及此类设备测量路面纹理的能力。本文件的目的是提供一个国际公认的程序，通过该程序，可以评估用于路面纹理测量的各种激光设备的性能。该文件包括旨在帮助激光轮廓仪用户验证其设备的指南和建议。本文件不作为鉴定或批准激光轮廓仪的依据。该程序旨在提供工具，以验证此类系统在所有方面的性能是否令人满意，这些方面对纹理的正确测量非常重要，并检测性能何时以及以何种方式不令人满意。本文件还提供了一些关于激光轮廓仪系统的限制和权衡的一般信息。用于路面测量的现代轮廓仪几乎完全是为二维或三维测量设计的非接触式（如激光点或线三角测量），本文件旨在评估此类轮廓仪的性能。然而，其他一些非接触式轮廓仪可以使用ISO？13473的适用部分。编制本文件的目的是为了纠正各种设备测量结果中不可接受的差异，即使这些设备的操作员声称它们符合ISO？13473的适用部分。它不适用于路面纹理测量以外的其他应用。为了能够排除因编程错误或对ISO 13473-1的错误解释而产生的错误，可通过附录a获得参考程序代码、数字配置文件和计算的参考MPD值。本文件是对ISO 13473其他部分的补充，其中给出了一些规范，但不包括检查这些规范的方法。

This document describes methods for checking laser profilometer performance with respect to the capability of such equipment in measuring pavement texture.The objective of this document is to make available an internationally accepted procedure by which performance of various laser-based equipment for pavement texture measurements can be evaluated. The document includes guidelines and recommendations intended to assist users of laser profilometers in verification of their equipment. This document is not intended as the basis for qualifying or approving laser profilometers. The procedure aims at providing tools for verifying that such systems perform satisfactory in all respects important for the correct measurements of texture, as well as to detect when and in what way the performance is unsatisfactory. This document also provides some general information about the limitations and trade-offs of laser profilometer systems.Modern profilometers in use for measurements on pavements are almost entirely of the contactless type (such as laser point or line triangulation) designed for two- or three-dimensional measurements, and this document is intended for evaluating the performance of this type of profilometers. However, some other contactless types of profilometer can use applicable parts of ISO 13473.This document has been prepared as a result of a need identified to correct for unacceptable differences in results measured by various equipment, even if the operators of these claim that they meet the applicable part of ISO 13473. It is not intended for other applications than pavement texture measurement. To be able to exclude errors influenced by programming mistakes or wrong interpretation of ISO 13473？1 a reference program code, digital profiles and calculated reference MPD-values can be reached via Annex A. This document is a complement to other parts of ISO 13473 in which some specifications are given but methods to check them are not included.
