It seems like the error stems from the fact that SIFT tune its octave
automatically, while ORB use a fixed umber of octaves.
A workaround might be either to tune the nlevels
params of the ORB
class according to the maximal detected octave
prior to descriptor extraction.
Alternatively, you may reject key points with octave
larger than ORB
's nlevels
.
