If the accuracy of the final output is set at the sub pixel level,
the output can be obtained at the sub pixel level regardless of
whether the 1st or 5th step is set at sub pixels. If you set the
1st step at sub pixels, the search will take an extremely long
time.
However, since it is possible to shorten the search time
without compromising final output accuracy by setting sub
pixels in the 5th step, we recommend reducing the search
time by setting and adjusting the sequencing, and confirming
the final search accuracy.
Since it is possible to set the correlation values (judgment
lower limits) independently in each search step, we
recommend setting them up separately to suit the step.
The image compression can be set from±16 pixels, but if the
size of the set template does not fulfill that condition, there
may be conditions under which the search accuracy cannot
be set.
24. Output Unit
This setting sets the data output order for the search results in the case that
more than one object was found.
