二维数字成像系统的性能取决于与光学和电子处理相关的几个因素。这些概念已经产生了标准，这些标准已经被设想用于摄影设备和二维扫描系统，并且这些标准已经旨在估计不同的参数，例如分辨率、噪声或动态范围。相反，目前不存在用于评估诸如激光扫描仪或图案投影测距相机的3D成像系统的相应性能的标准测试协议。本文的重点是调查的实验过程中评估一些关键参数的3D设备，通过扩展的概念定义的ISO标准的3D域。这项工作的实验部分涉及不同的范围传感器的特性，通过提取其分辨率，准确性和不确定性，从专门设计的测试对象的几何特性是已知的3D数据采集集。这方面的贡献的主要目标是建议一个简单的表征过程中产生一个可靠的比较不同的范围传感器的性能，并检查一个特定的设备是否符合预期的特性。
The performance of 2D digital imaging systems depends on several factors related with both optical and electronic processing. These concepts have originated standards, which have been conceived for photographic equipment and bi-dimensional scanning systems, and which have been aimed at estimating different parameters such as resolution, noise or dynamic range. Conversely, no standard test protocols currently exist for evaluating the corresponding performances of 3D imaging systems such as laser scanners or pattern projection range cameras. This paper is focused on investigating experimental processes for evaluating some critical parameters of 3D equipment, by extending the concepts defined by the ISO standards to the 3D domain. The experimental part of this work concerns the characterization of different range sensors through the extraction of their resolution, accuracy and uncertainty from sets of 3D data acquisitions of specifically designed test objects whose geometrical characteristics are known in advance. The major objective of this contribution is to suggest an easy characterization process for generating a reliable comparison between the performances of different range sensors and to check if a specific piece of equipment is compliant with the expected characteristics.
