“…Even though standards for investigations and tests of laser scanning systems still need to be defined, and simple and possibly low cost calibration methods must be found, several studies investigate laser scanner accuracy (Boehler et al 2003) (Ingensand et al, 2003) (Lichti et al, 2007) (Mechelke et al, 2007) (Russo et al, 2007) (Kersten et al, 2008). These usually refer to calibrated objects (often to plane objects).…”

ABSTRACT:The paper will present the extraction of information from a laser scanning survey aimed to support historical studies on the Sangallo's house in Florence. In order to verify some study's hypothesis related to the building history and constructive techniques, high resolution models were needed. The meaning of "resolution" applied to 3D scanning will be briefly discussed stressing the difference between resolution and accuracy. Starting from the analysis of technical specifications of the used instruments, the expected performance of the model is described. The results obtained from acquired data are shown and the paper will conclude proposing some answers to the historian's questions.

“…This sort of research is reasonable for evaluating the accuracy of the whole hardware-software structure, as the precision of 3D laser systems is composed of combination of errors in distance and angle measurements, and in the algorithm for fitting the targets in the point cloud (Kersten, 2009). Other approaches literally describe instrument's observation as "not of real interest" (Staiger, 2005).…”

Youth ForumKEY WORDS: laser scanning, collimation error, horizontal axis error, engineering geodesy, verticality measurement ABSTRACT:Aim of this study was to appoint values of collimation and horizontal axis errors of the laser scanner ZF 5006h owned by Department of Geodesy and Cartography, Warsaw University of Technology, and then to determine the effect of those errors on the results of measurements. An experiment has been performed, involving measurement of the test field , founded in the Main Hall of the Main Building of the Warsaw University of Technology, during which values of instrumental errors of interest were determined. Then, an universal computer program that automates the proposed algorithm and capable of applying corrections to measured target coordinates or even entire point clouds from individual stations, has been developed.

Abstract:The importance of landscape and heritage recording and documentation with optical remote sensing sensors is well recognized at international level. The continuous development of new sensors, data capture methodologies and multi-resolution 3D representations, contributes significantly to the digital 3D documentation, mapping, conservation and representation of landscapes and heritages and to the growth of research in this field. This article reviews the actual optical 3D measurement sensors and 3D modeling techniques, with their limitations and potentialities, requirements and specifications. Examples of 3D surveying and modeling of heritage sites and objects are also shown throughout the paper.
