Abstract

A new approach of high accuracy displacement field measurement in long-distance by digital image correlation is proposed. The long-distance measurement accuracy attained 1 micron with digital image correlation technique of 0.001 pixel bilinear interpolation. Integrated software package is exploited with language of c++ and Matlab under Windows system . It combined with optics hardware to constitute a multi-function instrument for displacement field measurement. This system have features of high accuracy, real-time and non-contact measurement with computer control and is especially effective in flexivity measurement of bridge and cloverleaf junction. It also fit for dynamic displacement field measurement when a high speed image card was used. This technology extend digital image correlation method's application field.
