CRISTAL: Dimensional Analysis

Videographic dimensional analysis is a process which allows
dimensional information to be extracted from digital images. 
This dimensional data establishes a foundation for creating
measured drawings or 3-D model representations of an
architectural resource. The Videographic Computer Assisted
Designer (VCAD), a two and three dimensional videographic
analysis system currently being developed by VideoCad Inc., was
selected for the research effort.  The VCAD System has the
capacity to construct the necessary geometry for extracting
dimensions from digitized (raster) images.  A three dimensional
reference stadia is included in the video recording of each of
the building views to be dimensioned.  These key reference views
are assigned labels when they are digitized from the videotape
source and stored in the digital database.
