Building Information Modelling (BIM) or Building Information Management, is a highly collaborative process that allows architects, engineers, real estate developers, contractors, manufacturers, and other construction professionals to plan, design, and construct a structure or building within one 3D model.
During the building phase it is highly desired to compare the actual (real) construction details with the 3D BIM design. For this purpose a LIDAR scan records 3D point clouds of the real situation, where engineers are interested in deviations from LIDAR and BIM. Comparison tools can show deviations between point cloud and 3D model. Such a tool enables visualization of deviations between scanned points and the model, with user-desired tolerances.
The goals of the project are to design and evaluate deep-learning algorithms for LIDAR versus IFC compatibility. In more detail:
