摘要：We present experimental results with uncertainty analysis method for a proposed distance measurement protocol for mid- range terrestrial laser scanners (TLS). Three-dimensional (3D) imaging systems evaluation is performed in the environmentally controlled laboratory at NRC-IIT with the use of specially designed reference test object (RTO), test procedures and mathematical methods. The procedure is based on the evaluation of point-to-point distance measurements. The distance measurements characterizing a system under test (SUT) are taken between comparative points of reference (CPOR) located on the RTO plane surfaces. Selected CPORs are the intersections of particular lines of measurements with estimated RTO plane surfaces. The virtual lines of measurement are determined by using a spherical RTO. Uncertainty analysis for fitted planes, virtual lines of measurements and CPORs is performed with our software utilities especially created for this purpose. Data on commercial products are provided for the sake of illustrating the proposed protocol
