Name Description
"Predefined settings" The "Predefined settings" drop-down menu contains four preset parameter blocks
which make it easier to edit parameters and contain the position recognition param-
eters for the corresponding contours.
■ Simple contour : Parameters for a simple contour.
■ Average contour : Parameters for more complex contours.
■ Complex contour : Parameters for highly complex contours.
■ Inner contour : Parameters for closed inner contours.
"Acceptance" Specifies the quality in percent at which position recognition is only just accepted in
order to obtain valid results. 100% quality: the entire model contour was found in
the camera image.
■ Typical fine position values: 65 - 90.
■ Typical approximate position values: 30 - 50.
"Accuracy" Specifies to what degree the image data are compressed during the position recog-
nition process. Higher values speed up the position recognition process, lower val-
ues slow it down.
If, for example, low sheet thicknesses with narrow edges are to be identified, a
smaller value must be selected.
■ Typical fine position values: 2 - 4.
■ Typical approximate position values: 3 - 4.
"Contrast" Displays the contrast in the last position recognition result.
"Elasticity" Specifies by how many the pixels the actual contour may vary at the most from the
required contour of the model to obtain a valid result.
Deviations which affect the quality can be caused by influences, such as machining
tolerances, burrs on edges, working distances etc.
■ Typical fine position values: 0 - 3.
■ Typical approximate position values: 3 - 4.
"Ignore Polarity" During position recognition, it is always assumed that the part in the camera image
is bright and the background is dark (shadows). If that is not the case "Ignore Polar-
ity" must be selected.
Tip
If the polarity of the edges is partially not constant, e. g. in the event of complex
contours or problematic surfaces, "Ignore Polarity" must be activated. This is not
necessary in the case of very simple contours (e.g. angles between two lines).
"Sort by position" If activated, the results are sorted according to their position, not their size, during
the fine position recognition process.
"Rough recognition" Display whether the loaded search contour has rough recognition.
"Fine recognition" Display whether the loaded search contour has a fine recognition.
"Image recording settings" Parameters for image recording can be set.
"Surface" The "Surface" drop-down menu contains four preset parameter blocks that can be
used for image recording in case of blanks with different surface properties.
Note
A change in the parameter block has an effect only if a new image recording has
been made.
■ Opaque : Parameters for an opaque surface.
■ Average : Parameters for a slightly glossy surface.
■ Reflecting : Parameters for reflecting surfaces.
■ Mirroring : Parameters for mirroring surfaces.
"Exposure time" Manual setting of the exposure time for snapshots.
■ 0: Low exposure time.
■ 30: Maximum exposure time.
