Edge Color Specification - For Color Cameras Only (Edge Position)
This item selects the color of the edges to be detected.
If the target color changes, this setting is not necessary.
If the color is not specified, positions in the
measurement region where the color changes drastically are detected as an edge.
1 In the Item Tab area, click [Edge color].
2 Place a check at "Edge color
specification" in the "Color setting" area.
3 This item selects the color to be
detected as edges.
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.
Setting method Description
Image Display area
Specify a region on the image that includes the target
co
lor. The average color of the specified
region is registered.
Color chart
Click the reference color on the color chart to specify it. The RGB values for the specified color
a
r
e displayed at the bottom.
R, G, B The color to be detected is set with the RGB values.
Difference R, G, B
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.
Detection mode
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 chang
es to
a color other than the specified
color is detected as the edge.
Reference position usage method: Measuring the distance from a specific position
• Positional deviation can be inspected by calculating the difference between
the referen
ce position and the measured position with an expression.
After changing the reference position to a
n
y desired position, changing the
measurement region will automatically change it back to the default
position.
