Abstract:
Work at the National Institute of Standards and
Technology on laser radar imaging of a construction site
is described. The objective of the research is to make
measurements required in a construction project quicker
and cheaper than current practice and to do so without
impacting existing operations. This can be done by
developing techniques for real-time assessment and
documentation in terms of 3-D as-built models of the
construction process. Once developed, this technology
may be used for other applications such as condition
assessment of a hazardous environment where human
intervention would be impossible.
