[Model (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, ensure the position of the measurement object to be correct when 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 Parameter]
Specify a region to be registered as a model by using one of the Drawing tools.
User's Manual, "Setting Figures"
Table: Drawing Tools Available for Model (Search)

Rectangle

Circle

Circumference

Polygon
Note
- If the model is an ellipse, its circumscribed rectangle is displayed as the search result of the model.
To save the registered model image, check the [Save registered model] option.
Tap [OK].
The model is registered.

Note

If you want to change only the detection coordinate after registering the model, set up [Detection point].
[Detection point (Search)]
'Registered model image' refers to the image saved when a model is registered. Saving a registered model image allows you to modify model parameters using that registered model image even when the actual measurement object is not present. Note that the scene data size increases when a registered model image is saved.

For the following operations, see

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.

Note

In the "Model parameter" area, select the search detection method and specify a value for each item.

Table: Model - Model Parameter
Setting Item	Set Value [Factory Default]	Description
Search mode	[CR]	This search mode detects areas with a high degree of correlation between the registered model image and the input image.
Search mode	PT	This search mode detects areas with a high degree of shape similarity between the registered model image and the input image. It is available only when 3 Mega pixel color camera is connected. User's Manual, "Configuring Search"

When "CR" is selected:

Table: Model - Model Parameter - CR
Setting Item			Set Value [Factory Default]	Description
Rotation			Checked [Unchecked]	Specify whether to rotate the image during a search.
	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.
	Smart mode		[Checked] Unchecked	Specify whether or not to enable Smart mode. Checking the [Smart mode] option enables a high-speed rotation search. The stability may be lowered when the model shape aspect ratio is large or when the NOT mask is used.
Stab. (Stability)			1 to 15 [9] (for cameras with more than 640 by 480 pixels) [12] (for cameras with 640 by 480 pixels or less)	Specify the stability of detection. A larger value increases stability. A smaller value speeds up processing. If lowering stability leads to slower processing, it is likely that many candidates have been detected. In this case, specify a larger value for [Candidate LV] or [Stab.].
Prec. (Precision)			1 to 3 [2]	Specify the position precision of the measurement coordinates. A larger value increases precision, and a smaller value speeds up processing.

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 [>].
The values for "Stab." and "Prec." can be specified by dragging the slider.
The value can also be adjusted by tapping the buttons at both ends of the slider.

When "PT" is selected:

Table: Model - Model Parameter - PT
Setting Item			Set Value [Factory Default]	Description
Rotation			[Checked]	When "PT" is selected for "Search mode", search cannot be performed without rotation.
	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
Stab. (Stability)			1 to 5 [3]	Specify the stability of detection. A larger value increases stability, and a smaller value speeds up processing. If lowering stability leads to slower processing, it is likely that many candidates have been detected. In this case, specify a larger value for "Candidate LV" or "Stab.".

If necessary, specify a value for each item.
Tap [...] for "Angle range" and specify the range of the rotation angle.
How to input a value: User's Manual, "Inputting a Value"
The value for "Stab." can be specified by dragging the slider.
The value can also be adjusted by tapping the buttons at both ends of the slider.

To improve measurement results, make adjustments as described below.

For adjustments, see also

If the model image consists of detailed figures, specify a larger value for "Stab.".
If images that should be judged OK based on the model image vary in some degree, specify a smaller value for "Candidate LV".
If the measurement results are unstable only when "Rotation" is selected, specify a smaller value for "Skipping angle".
When "Rotation" is selected, if the model region shape is complex, uncheck the "Smart mode" option.

If the model image is a simple figure or a large figure, specify a smaller value for "Stab.".
If images that should be judged OK based on the model image, have less variation, specify a larger value for "Candidate LV".
When "Rotation" is selected, if the model image is a simple figure, specify a larger value for "Skipping angle".
When "Rotation" is selected, if the model region shape is simple, check the "Smart mode" option.

Display a registered model in the "Image display" area.

In the "Registered model image" area, tap [Disp model].
The registered model image is displayed in the "Image display" area.
In the "Registered model image" area, tap [Input image].
The previous input image is re-displayed in the "Image display" area.

When model parameters are modified, re-register the model.

In the "Registered model image" area, tap [Disp model].
The registered model image is displayed in the "Image display" area.
In the "Registered model image" area, tap [Re-register].
The model is re-registered using the modified model parameters.

To delete the registered model image:

In the "Registered model image" area, tap [Delete].
A confirmation message appears.
Tap [Yes].
The registered model image is deleted.
