comparison based on the cost
The cost of the rangefinder is very low compared to the other devices (laser
scanner and Total Station) used in this research (See Fig. 10 ). The time necessary
for data collection using the rangefinder and model reconstruct ion is lower than in
the case of laser scanner and Total Station. Data storage required for Faro Photon
120/20 data was 8 GB as it was set for high resolution data and required data stor-
age for LaserAce 1000 modelled by DHE data structure was 8 KB. Data storage
required for Total Station was 25 KB in CityGML data format. Data processing
(pre-processing and post-processing) of Faro Photon 120/20 required high mem-
ory space and high performance workstation which significantly increase time and
cost of a project.
6 Assessment of Trimble LaserAce 1000 in Indoor
Building Surveying
Trimble LaserAce 1000 for indoor environment surveying was investigated. Three
rooms including a corridor and two rooms were measured (See Fig. 11 ). Rooms
were fully furnished and to measure all corners of a room there was a necessity
to change position of the rangefinder. As can be seen in Fig. 11 , two rooms inter-
sected each other which have been caused due to disorientation of the rangefinder
in indoor environment.
