Filling Lacunas in Terrestrial Laser Scanning Data:

چکیده
Laser scanning methodology allows to reconstruct the metric characteristics of objects at different LOD (Level Of Detail) providing spatially dense points clouds. In particular, the terrestrial application carried out in the last years have demonstrated the potentialities of the methodology useful in many different sectors. This tecnique has been used also for the “Cavallo ligneo” of the “Palazzo della Ragione” (Padua, Italy) survey providing useful data for the restoration of the wooden horse. Due to the morphologic complexity of the object, some lacunas were created during the points clouds acquisitions: different procedures to filling lacunas were considered and applied providing a complete 3D model of the wooden statue.

Occlusion Area as Suitable Guidance for Terrestrial Laser Scanner Localization
Terrestrial Laser Scanner (TLS) technology, have altered quickly data acquisition for map production in surveying. In many cases, it is impossible to complete surveying of the desired area without TLS displacement in one station to another. Occlusion is innate in data acquisition, with this type of device. To solve this problem, TLS devices should be placed in different locations and scanning o...

متن کاملSemi-Automatic Registration of Airborne and Terrestrial Laser Scanning Data Using Building Corner Matching with Boundaries as Reliability Check
Data registration is a prerequisite for the integration of multi-platform laser scanning in various applications. A new approach is proposed for the semi-automatic registration of airborne and terrestrial laser scanning data with buildings without eaves. Firstly, an automatic calculation procedure for thresholds in density of projected points (DoPP) method is introduced to extract boundary segm...

متن کاملTree Height Growth Measurement with Single-Scan Airborne, Static Terrestrial and Mobile Laser Scanning
This study explores the feasibility of applying single-scan airborne, static terrestrial and mobile laser scanning for improving the accuracy of tree height growth measurement. Specifically, compared to the traditional works on forest growth inventory with airborne laser scanning, two issues are regarded: "Can the new technique characterize the height growth for each individual tree?" and "Can ...
