In the image above, allowing shared edges would mean that the positions in box
B are found, with scores of 100% (E) and 75% (F) respectively. If you do not allow
shared edges, position 1 will still be found, with a score of 100%, while the score
for position 2 will be further reduced. This is because an additional edge is missing
from the found position when compared to the teachin position.
Position Settings
The following settings apply at position level, i.e. they only affect the current
position. It is easy to switch between positions: just click the arrows to change
position.
Score
The Acceptance value specifies the minimum value (%) for identification of a
position. It corresponds to the Score value previously specified on the Parameter
tab. When the system is searching for a position and finds it with a score of 85%,
for instance, it will continue searching for a better match until all other possibilities
have been ruled out, or until it reaches timeout. To speed up the identification
further, use the Certainty setting. The Certainty parameter is used to end the
search process as soon as a position that meets the certainty setting is found.
Score target
The Acceptance value specifies the minimum value (%) for identification of a
position. It corresponds to the Score target value, previously specified on the
Parameter tab. When the system is searching for a position and finds it with a
score target of 85%, for instance, it will continue searching for a better match until
all other possibilities have been ruled out, or until it reaches timeout. To speed up
the identification further, use the Certainty setting. The Certainty parameter is
used to end the search process as soon as a position that meets the certainty
setting is found.
