LS Detect

Search for figures that match the specified tone, width, height, and distance to neighboring figures, and create measurement point for each figure found.

How to Execute

Using LS Detect Dialog

Click the toolbar icon to open LS Detect dialog, and then click New Condition button to add a new search condition. Modify the conditions, then specify the search area in Area. Then, click Execute to execute LS Detect.

LS Detect Dialog

Item Action
Name Specify a condition name.
Tone Specify the tone of the search location.
XY Specify the direction in which to create a measurement point.
Type Specify the order in which to create a measurement point.
W Specify the width of the figure in the measurement direction.
L Specify the width of the figure in the vertical direction for measurement direction.
D Specify the distance to an adjacent figure in the measurement direction.
Grouping Specify the method of grouping after creating measurement points.
Target Count Specify the maximum number of points to create when LS Detect is executed.
Area Specify the area where LS Detect is executed.

W means the width of the figure in the measurement direction, L means the width of the figure in the vertical direction for measurement direction, and D means the distance to the adjacent figure in the measurement direction.

LS Detect Condition

You can also add more criteria in Advance tab.

LS Detect Dialog Advance

Item Action
Angle Tolerance Specify the angle error tolerance when a slant is specified for XY.
Manhattanize Tolerance Specify the coordinate error tolerance when a slant is specified for XY.
Jog Length to Ignore Specify whether jogs should be tolerated when searching for figures for measurement point creation. Refer to With Jog in Adding Measurement Points page.
Joint Width Mode Specify type of Jog measurement.
Ignore Assist Feature Ignore small figures or spaces when searching for figures for measurement point creation. Refer to Assist Size in Adding Measurement Points page.
Spacing in Single Feature Interval size for multiple detections on a figure.
Duplicate to Target Count Force to satisfy detect count with overlap.

Extract and Execute Conditions from Measurement Points

LS detect condition can be extracted from existing measurement point. Right-click on a site in datalist of Measurements tab in Measurement Panel, then select Create LS Detect Condition to add its condition to the LS Detect dialog. The following conditions are extracted:

Condition Syntax
W Length of measurement point - margin ≤ W ≤ Length of measurement point + margin
L ROI height of measurement point ≤ L
D Distance to the adjacent figure, or length of measurement point, whichever is shorter / 2 ≤ D

Margins can be specified in Preference. See LS Detect/Margin in Preference Action/Recipe Creation/Add Measurement page.

It is also possible to directly perform LS Detect on the surrounding area with conditions extracted from a measurement point. Right-click a measurement point in Measurements tab of Measurement Panel and select LS Detect with Item/Search Around from context menu to open Search Size dialog. Enter the area and press OK to perform LS Detect within the specified area around the point, using the conditions of the point.

Execute Using Measure Points File

Click the icon on Measurement Panel and select Load Measure Points File to open the Load Measure Points dialog.

File Dialog

Specify a file name and press OK to execute LS Detect using the conditions and associated regions specified in the file. It is also possible to create a measurement point, extract conditions on that point, and execute LS Detect using the extracted conditions around specified area, all at the same time.

Refer to Measure Points File page.

Display the Result of LS Detect Execution

The measurement points created by LS Detect is added the datalist of Measurements tab in Measurement Panel. The result is shown in Result tab in the LS Detect dialog.
