[Model (ECM Search)]

Important

When a model is registered, the central coordinates of the model are registered as the detection coordinates (if multiple figures are combined, the central coordinates of the circumscribed rectangle are registered). For this reason, place the measurement object in the correct position when registering a model.
Upon re-registering a model, error models are deleted. Register error models when re-registering a model.

In the "Item tab" area, tap [Model].
When setting a new model, you do not have to tap [Model].
If necessary, set up the "Model parameter" area.
Changing Model Parameters
Specify a region to be registered as a model by using one of the Drawing tools.

The registered model image is displayed in the "Image display" area.

Note

If you want to change only the detection coordinate after registering the model, set up [Detection point].

Changing Model Parameters

This item can be changed if necessary. Usually, the factory default value can be used.
When any settings have been changed, verify whether measurements can be performed correctly through actual measurement.

In the "Model parameter" area, specify a value for each item.

Table: Model (ECM Search) - Model Parameter
Setting Item			Set Value [Factory Default]	Description
Rotation			Checked [Unchecked]	Specify whether to rotate the model.
	Angle range	Upper	-180 to [180]	Specify the upper and lower limit values for "Angle range" (rotation angle) during a search. The normal direction is clockwise. Settings must satisfy: lower limit upper limit.
	Angle range	Lower	[-180] to 180
	Skipping angle		1 to 30 [5]	Specify the stepping angle (in degrees) by which the model is rotated to create rotated models. A smaller angle increases stability, but slows down the processing.
Reverse			Checked [Unchecked]	Specify whether to allow reverse of lights and darks for the model.
Size change			Checked [Unchecked]	Specify whether to allow size change for the model. When checked, tap [Detail] and specify a value for each item.

If necessary, check "Rotation" and specify a value for each rotation item.
For "Angle range" and "Skipping angle", tap [...] and specify a range of the rotation angle.
How to input a value:User's Manual, "Inputting a Value"
The [Skipping angle] value can be adjusted by tapping [<] or [>].
If necessary, check the "Reverse" or "Size change" option.

When the "Size change" option is checked, tap [Detail].

The "Model parameter: Size change" area is displayed.

Model - Model Parameter: Size Change Area

Table: Model (ECM Search) - Model Parameter: Size Change
Setting Item		Set Value [Factory Default]	Description
Move axis		[XY] X Y	Specify the direction in which to change the model size.
Move range (%)	Upper	50 to 150 [110]	Specify the range in which to change the model size.
Move range (%)	Lower	50 to 150 [90]	Specify the range in which to change the model size.
Skipping width (%)		10 to 99 [10]	Specify the stepping percentage by which the model size is changed within [Move range] to create resized models. A smaller width increases precision, but slows down the processing.

Tap [...] or [] and specify a value for each item.
How to input a value:User's Manual, "Inputting a Value"
The [Skipping angle] value can be adjusted by tapping [<] or [>].

Tap [Return].
The "Model parameter" area is displayed.

Registering a Mask

By registering a mask, the part you do not want included in the model is excluded.

Tap [Mask].
The "Figure setting" area is displayed.
Specify a figure to be registered as a mask by using one of the drawing tools.

Extracting Edges

This item can be changed if necessary. Use this item when specifying the edge extraction parameters.

Important

When two different sets of [Edge extraction] settings are needed for the model registration and for measurement:

Change the [Edge extraction] settings after registering a model.
Note that, if the model is re-registered after the change, the changed settings are reflected in the registered model.

In the "Item tab" area, tap [Edge extraction].

In the "Edge extraction setting" area, tap [...] or [

] and specify a value for each item.

The "Edge level" value can be specified by dragging the slider or tapping one of the buttons at both ends of the slider.

How to input a value:

User's Manual, "Inputting a Value"

Table: Model (ECM Search) - Edge Extraction Setting
Setting Item	Set Value [Factory Default]	Description
Mask size	3x3 [5x5] 7x7 9x9	Specify the range of pixels which are used to extract the edge. With a larger mask size, search is less affected by variation in pixels.
Edge level	0 to 255 [100]	Specify the background suppressing level for an image of which the edge is extracted. Adjust the edge level when the edge is hard to see, due to low contrast with the background, or when unnecessary background noise should be removed.
