ABSTRACT

Nowadays, the graphic information needed by the specialists in different engineering
fields or in the cultural heritage sector has to be very accurate. Thus can be explained
the widespread usage of the three - dimensional data, because, first of all, it offers a
better visualization of the studied object and also, facilitates a better understanding of
the behaviour of the 3D model under specified loads by means of layouts showing cross
sections and elevations.
The aim of this paper is to bring forward the stages that must be followed when using
terrestrial scan station in order to obtain the 3D model of a chapel, efficacious in
assessment and monitoring of churches, part of cultural heritage, thus contributing to
historic conservation.
Moreover, by means of presenting state of the art technology, such as the Leica Scan
Station C10 with unprecedented versatility and major productivity for as-built and
topographic surveys, the paper shows its high level of topicality.
This paper has as goal, beside its educational purpose, the presentation of methods and
materials specific for terrestrial laser scanning technology that are in close connection
with surveying engineering and have to be used for 3D – and terrain modeling. These
are Leica C 10 Scan Station and its equipments: standard tripod, standard tribrach, laser
plummet and instrument height meter and the Leica Cyclone 7.1.1 software. It describes
both the fieldwork and the processing of the measured data.
The value of this paper lies in stressing the importance of the terrestrial 3D laser
scanners and the practical applications they have in many domains, such as: historic
conservation, by means of assessment and monitoring of churches, part of cultural
heritage, architecture, land surveying, archaeological studies, bridge structures,
assessing the risk of slope instability along transport corridors and highway surveys.

Keywords: 3D modeling, point cloud, laser scanning, historic conservation, terrestrial
