Method & Evidence

AimTo develop and validate a semi-automatic procedure for efficiently transforming 3D point cloud data from laser scans of complex buildings into accurate 3D finite element models suitable for structural analysis.
MethodProcedural modelling and comparative analysis
ProcedureThe procedure treats a 3D point cloud as a series of stacked cross-sections. Algorithms are employed to process these sections, generating a discretized geometry (voxel elements) that represents the entire 3D structure. This generated model is then compared to a CAD-based model of the same historical building for validation.
