Hybrid Modelling:For point cloud data from LiDAR,global modelling cannot make
good use of such high-density 3D data points.Therefore,we designed a novel hybrid
model,which includes \meta-deformation" for a small area (e.g.,cells in our case),\sub
deformation" for a partial area where the deformation is more or less uniform or con
sistent,and \deformation-map" for describing the complete region.With such a hybrid
deformation model,we are able to provide a more informative description of heterogeneous
deformation for a large monitored region.Furthermore,the deformation can be computed
incrementally according to this hybrid modelling.
Cell-based Deformation Computation.To effectively utilise the hybrid deformation mod
lling for a large region and to efficiently compute the deformation map,we design a novel
and self-contained cell-based deformation computing framework.With this framework,we are
able to automatically and incrementally compute the deformation information,from the meta
deformation for cells,to the sub-deformation for partial areas,and finally to the deformation
map for the complete region.This framework has three main steps (technical components),
namely,\split",\detect",and \merge".
