Parameters:
Min Position Expected
This allows you to specify the minimum value of the detectable position.
Max. Position Expected
This allows you to specify the maximum value of the detectable position.
Sensitivity
This represents the sensitivity level, that is the level of edge detection precision. Set sensitivity
affects processing results; the lower the sensitivity, the greater the accuracy.
Variation type
This establishes how the edge is to be detected during image acquisition. Possible values are:
From white to black: an edge feature is detected when it changes from white to black;
From black to white: an edge feature is detected when it changes from black to white;
Both: a feature is indicated as an edge feature when it changes from white to black and
black to white;
Automatic: the system automatically detects the edge feature.
Noise reject
This is used to reduce noise during the edge detection process. It establishes the minimum
variation in brightness of a feature in order for it to be considered an edge.
Direction
This determines the direction and edge detection path inside the ROI. This can be one of four
values:
From left to right (default value);
From right to left;
From top to bottom;
From bottom to top.
Result
If the detected edge value is between the minimum and maximum values set by the user, the
control gives a positive result. If no edges are found, or their values are not within the thresholds,
the result will be negative.
Example
Let's add a "position" control to the current inspection tool, so we can check that a cap is inserted
correctly on a detergent bottle.
Let's select "Position" from the Controls menu and then press the
SET
button.
