Teach sequence (doubled teaching): 8
1. Define correlation values for Teach picture 1 with both templates. (e.g. +0.9 with Template
"place" and +0.4 with Template "no placement.")
2. define correlation values for Teach picture 2 with both Templates. (e.g. +0.3 with Template
"place" and +0.95 with Template "no placement")
3. Calculate differences of the correlation values for each Teach picture: (here picture 1: 0.9
- 0.4 = 0.5; picture 2: 0.3 - 0.95 = -0.65).
4. Calculate thresholds from the difference values. (here: lower threshold -0.27; upper
threshold 0.12).
Recognition sequence:
1. Define correlation to Template "no placement" (e.g. 0.83)
2. Define correlation to Template "placement" (e.g. 0.31)
3. Calculate the difference: 0.31 - 0.83 = -0.524.The comparison with the thresholds result
in: "no placement" (-0.52 < -0.27)
Overlay for classification result: The blue length bar show the determined difference of the
correlation values and it show that the classification result is in the range for: "no placement".
Characteristic:
· => Relative calculation time intensive
· => Evaluate in difference to 'Singular Feature' the complete area of the pattern; not only
the outline of the structure. (The definition for the fiducial outline is not necessary to be high
precise.)
· => Need a defined shape at least for the class, the correlation have to be defined.
· => Transport tolerances could be eliminated also if the option "position recognition before
bad mark recognition" is inactivated.
