Reflect In Total Judgement; Changing Edge Detection Conditions (Sensors With Monochrome Cameras Only); Unstable Edge Position Results - Omron FQ2-S Series User Manual

Note
• You can change the output form for each measurement value to one of the following settings.
− [Result type] on the right of the display.
Press [ ]
Absolute value (default): The measured coordinates are output as absolute values.
Relative value: The difference from the reference value is output.

Reflect in Total Judgement

You can specify whether to reflect the judgement results of an inspection item in the overall judgement. (The
default is to reflect them.)

Parameter Description
Projection A projection is formed based on the gray level, and any position of intersection
between the gray level value and the threshold (edge level) is detected as an
edge.
This detection method is used when you must process an image with exces-
sive noise or when the edges are blurry.
Differentiation A differentiated waveform is created that represents the amount of change in
gray level between neighboring pixels. The maximum value of the differenti-
ated waveform that exceeds the threshold (edge level) is detected as an edge.
This detection method is used for low-contrast images.
Light to Dark Detects as an edge any position within the specified region that changes from
white to black.
Dark to Light Detects as an edge any position within the specified region that changes from
black to white.

Setting Description
Color diff. / density diff. Set the color change level to detect as an edge.
(%) The edge point is found based on a threshold that is set for a color change.
