The low and sub-models are always found using the taught (low) threshold.

Any score above it or equal to it is considered to be a success, so in these

cases there is no use for this algorithm.

The algorithm is performed as follows:

1 Find the main model as in the usual algorithm (no change for low

models).

2 Check the find score:

• If it is above the parametric high threshold, the find succeeded (no

change).

• If it is below the taught low threshold, the find failed (no change).

• If it is between the high and the low thresholds:

3 Move the camera to the sub-model.

4 Find the sub-model.

5 Determine if the distance (X, Y) between the main model and the sub-

model is within tolerance.

6 Move back to the main model and find it again.

In case the threshold score at which the sub-model was found, and the

distance between the main model and the sub-model are within tolerance,

the main model is regarded as successfully found. Otherwise, the model

finding procedure is considered failed.

Note, that during spiral/directional searches the system searches for

models with the taught (low) threshold. If the model with this low

threshold is found, a regular find operation will be performed at the finding

location, this time using the algorithm, described above. The new

parameters - Low Model High Score, Main Model High Score and Sub

Model High Score are given in the parameter tables in

Appendix 3.

6.1.4 Choice of Cutting Angle by Panel

There are two viable options for aligning and cutting Multi-Panels, each

appropriate for certain situations.

Standard: cut all angles on all panels either by:

• Cutting each angle on all panels in turn or

• Cutting all angles on each panel in turn.

Note: If no sub-models are taught, this algorithm is not performed even if the

parameter Use Sub-model is set to "Yes".
