摘要：

A low cost physical artifact with traceability to the national standard - meter is used for the metrological comparison of two terrestrial laser scanning systems: Riegl LMS Z390i and Trimble GX. The artifact is based on five spheres equidistantly situated and seven cubes of different dimensions. Accuracy and repeatability are evaluated using least squares fitting (LSF) and random sample consensus algorithms, for the study case of the spheres, and plane LSF and statistical analysis for the cubes. The horizontal resolution is evaluated using a modulated transfer function approach and the vertical one with the accuracy and repeatability data along Z axis. The Trimble system shows better results for all parameters, artifact parts, and algorithms under study. (C) 2011 Society of Photo-Optical Instrumentation Engineers (SPIE). [DOI: 10.1117/1.3646395]
