Vision metrology and three dimensional visualization in structural testingand monitoring

This paper describes initial work carried out to advance the Erse of vision metrology and three dimensional visualization techniques in structural tes ting and monitoring. A description is given of a methodology for semi-autom atically generating dynamic three dimensional computer graphics models, whi ch is employed to provide a three dimensional spatial framework for convent ional engineering instrumentation. The use of techniques developed for two structural measurement applications is explained and opportunities for curr ent and future research are reported.
