Laser scanning for BIM

Obtaining useful data from reality capture devices, such as Terrestrial Laser Scanners (TLS), for the extraction of semantic information and its subsequent use to support Building Information Modelling (BIM) cases (e.g. Scan-to-BIM or Scan-vs-BIM -based cases) is a complex task that requires planning execution expertise. Point clouds quality need be produced following conscientious scanning. And once point are acquired, methodical pre-processing operations vital ensure finally high quality. This paper summarises some guidelines surveyors successful acquisition campaign, especially when these will employed automatic processes involving BIM, Scan-vs-BIM. The also recipients involved in those processes, BIM modellers Quality Control (QC) managers.
