The 3D laser scanning is a convenient and accessible technology to document the existing infrastructure including buildings. The output is set of data points in space, so called point clouds. While point clouds can be directly rendered and inspected, they need to be converted into BIM representation for efficient digital processing.

The PointCloud2BIM library provides a set of algorithms to facilitate the processing of Building Point Clouds and identification of fundamental entities, such as floors, rooms, walls and openings.

The PointCloud2BIM library is written in C++. It can be integrated into any BIM software to assist the conversion of point clouds into digital BIM representation.

This reference manual documents the API of the library.

Note, that the library can also be used as a standalone tool without any dependency on BIM software by offering a set of command line tools that can perform the typical steps in the trasformation from the point clouds to BIM representation.

The library can be obtained from Department of Mechanics, Faculty of Civil Engineering, Czech Technical University. Please contact Borek Patzak (borek.nosp@m..pat.nosp@m.zak@f.nosp@m.sv.c.nosp@m.vut.c.nosp@m.z) for details.
