CHEN Hua, YE Dong, CHEN Gang, et al. Digital image correlation search method based on genetic algorithm[J]. Optics and precision engineering, 2007, 15(10): 1633-1637.DOI:
A new search method based on genetic algorithm is proposed
and the experiment is done. The experiment results indicate that the stand deviation of
u
is 0.022 pixel
and the stand deviation of
v
is 0.032 pixel. The method can meet the requirements of nonlinear and multi-peak global optimization in the digital image correlation with high precision and rapid speed
and can avoid the initial value selection
which is better than the conventional search methods.
