Reference Setting (Edge Positions)

When the measurement region is set, this position is automatically set at the same time as the reference
position. This item can be used to change the reference position to any desired position.
Note
Reference position usage method: Measuring the distance from a specific position
• Positional deviation can be inspected by calculating the difference between
the reference position and the measured position with an expression.
After changing the reference position to any desired position, changing the
measurement region will automatically change it back to the default
position.
FH/FZ5 Processing Item Function Reference Manual
Specify a region on the image that includes the target color. The average color of the specified
region is registered.
Click the reference color on the color chart to specify it. The RGB values for the specified color
are displayed at the bottom.
The color to be detected is set with the RGB values.
This sets the allowable color difference for detecting the edge, using the specified color as the
reference. The larger the difference values, the larger the color range that is used to detect the
edge.
Color IN: The position where a color other than the specified color changes to the specified
color is detected as the edge.
Color OUT: The position where the specified color changes to a color other than the specified
color is detected as the edge.
