Measurement Parameters (Scan Edge Positions)

Measurement parameters can be changed as needed to address unstable measurement results.Normally, the factory default value will be used.

After changing a setting, check whether measurement can be done properly by performing an actual measurement.

In the Item Tab area, tap [Measurement].
The edge profile of the measurement region is displayed as a graph in the Image Display area.

Set the value of each item in the "Display area" area.

Setting item		Set value [factory default]	Description
Display area No.		[0] to 99	Specify the area for which the edge profile is displayed.It should be a sequential number decided when the area was divided.
	Enabled	[Checked] Unchecked	Specify enable/disable for the displayed divided area.When disabled (unchecked) is specified, that area is not measured.

Set the value of each item in the "Measurement" area.

For color cameras:

Setting item	Set value [factory default]	Description
Edge No.	0 to 99 [0]	Specify the edge number used to extract edges. Edge numbers are assigned to detected edges starting from 0 and going on in the direction from the start point (the arrow point) to the end point (the direction of arrow) in the selected area.
Edge level	Position (%) for width of a color 0 to 100 [50] Value of color 0 to 442 [20]	Select a color difference level with which the edge is detected. See "User's Manual", "Edge level"
Edge color level	0 to 442 [100]	This emphasis level can be specified only if the edge color to detect is specified.

For monochrome cameras:

Setting item	Set value [factory default]	Description
Measure type	[Projection] Derivation	This sets the type of edge measurement.
Density change	[Light→Dark] Dark→Light	Select whether a black-to-white change or a white-to-black change should be recognized as a density change in the specified region.
Edge No.	0 to 99 [0]	Specify the edge number used to extract edges. Edge numbers are assigned to detected edges starting from 0 and going on in the direction from the start point (the arrow point) to the end point (the direction of arrow) in the selected area.
Edge level	Position (%) for width of a density 0 to 100 [50] Value of density 0 to 255 [20]	Select the density change level to be detected as edges. See "User's Manual", "Edge level"

If necessary, set each item in the "Noise removal" area.

Setting item	Set value [factory default]	Description
Noise level	0 to 442 [5]	When detection is affected by noise, increase this value. See "User's Manual", "Noise level"
Noise width	0 to 9999 [0]	Set the width for judging noise. When detection is affected by noise, increase this value. See "User's Manual", "Noise width"

In the "Approximate line" area, specify the point to be used for the calculation of approximate lines.

Setting item		Set value [factory default]	Description
Noise cancel		ON [OFF]	When a check is placed at [ON], an approximate line is found by excluding the points with large deviation among the measured points.
