Recently, a laser scanner has been receiving more attention as a useful tool for real-time 3D data acquisition, and various applications such as city modelling, DTM generation and 3D modelling of cultural heritage were proposed. However, robust filtering for distinguish onand off-terrain points from point cloud 3D data collected by airborne laser scanner is still issues. In particular, filterin...

An entire roadway system represents a crucial element in the sustainable urban transportation planning process. Pavement surfaces are at continual risk of accumulating serious deteriorations and defects throughout their service life due to traffic loading environmental impact. Since networks growing rapidly, relying on visual pavement inspection is not always feasible. Therefore, this paper pro...

Terrestrial Laser Scanner is a key methodology in cultural heritage survey, as it allows the representation of objects with high accuracy from the geometric point of view but also allows the generation of graphic representations of high visual impact for public (non technical) audience. For the survey of monumental structures, for which it is difficult to have contact with the object because of...

GPS/INS integration can provide high accuracy (centimeter level) navigation under good satellite geometry and atmospheric conditions. However, due to GPS signal blockage and accumulative error attributes of INS, a GPS/INS system cannot continuously maintain such high accuracy navigation during GPS outages, which may frequently happen in terrestrial applications, such as when navigating in fores...

Abstract Currently, the need for a 3D model that represents existing condition of building is needed, especially management. While performed mapping utilities such as pipelines in buildings, Terrestrial Laser Scanner (TLS) technology couldn’t cover object ceiling, so Handheld (HS) was used to complete scanned objects. The purpose this article conducting process between HS and TLS pipelines. int...

Terrestrial laser scanning broadens its application areas in civil engineering, and claims even more attention in engineering survey. The paper shows the results of a laboratory test of a laser scanner. The laboratory test involved complex 3D accuracy analysis, reflectivity investigation of different colors and materials used at construction sites and observation of reflection angles. Instead o...
