ABSTRACT
All constructions are permanent subjected to risk factors and monitoring damaged buildings so, in this case requires the use of techniques which provide rapid and safe measurements even in emergency conditions. Improvement of geodetic instruments, technologies for measurements and automated data processing has created new possibilities for their use in civil engineering. Terrestrial laser scanning (TLS) method is accurate, fast and can satisfy these requirements, since they produce dense point clouds in little time and also allow an accurate geometric modelling of observed buildings. The data can be combined with photographic images obtained by a high resolution camera, using computer software, in order to produce building models. This paper presents the application of terrestrial laser scanning for the assessment of building damages located in Bucharest. The results can be used to take decisions quickly and effectively regarding damaged buildings even in emergency conditions.
