Abstract
Purpose - The purpose of this research is to
outline in detail the procedure of remote data
capture using laser scanning and the subsequent
processing required in order to identify a new
methodology for creating full engineering drawings
(orthographic and 3D models) from laser scan and
image survey data for historic structures.Design
methodology approach - Historic building information
modelling (HBIM) is proposed as a new system of
modelling historic structures; the HBIM process
begins with remote collection of survey data using a
terrestrial laser scanner combined with digital
cameras. A range of software programs is then used
to combine the image and scan data.Findings -
Meshing of the point cloud followed by texturing
from the image data creates a framework for the
creation of a 3D model. Mapping of BIM objects onto
the 3D surface model is the final stage in the
reverse engineering process, creating full 2D and 3D
models including detail behind the object's surface
concerning its methods of construction and material
makeup, this new process is described as
HBIM.Originality value - The future research within
this area will concentrate on three main stands. The
initial strand is to attempt improve the application
of geometric descriptive language to build complex
parametric objects. The second stand is the
development of a library of parametric based on
historic data (from Vitruvius to 18th century
architectural pattern books). Finally, while it is
possible to plot parametric objects onto the laser
scan data, there is need to identify intermediate
software platforms to accelerate this stage within
the HBIM framework.
