The imaging measurement system must be calibrated before application. In calibration procedure
sub-pixel center extraction is the crucial step for the final accuracy. In this paper
a new sub-pixel extraction method is proposed. Edge detection at pixel level is obtained using LOG operator
then sub-pixel edge detection is realized using the Facet model. Finally
the least squares ellipse fitting is operated on the sub-pixel edge to determine the sub-pixel center. Experiment on a series of simulated images indicates that this algorithm is able to realize the center location accuracy of 0.01-0.02 pixel
and meets the requirement of sub-pixel level. (2012) Trans Tech Publications

Because the underwater velocity of supercavitating projectile is very high
its structure undergo high longitudinal force. It is necessary to perform structure buckling reliability analysis because the randomicity of structural own parameters and flow parameters should be considered. Critical buckling load of supercavitating projectile is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each random variable are deduced
and structural buckling reliability index is calculated by limit step length iteration method. Numerical results show that the critical buckling load and structural buckling reliability index increase with the increase of the ratio of base diameter to cavitator diameter. And structural buckling reliability index increase with the decrease of velocity coefficient. 2011 IEEE.
