Rotation Adjustment (Feature Extraction) - Panasonic MICRO-IMAGECHECKER AX40 User Manual

6.19 Rotation Adjustment (Feature Extraction)

6.19.1 Setting Procedure
The detection and setting procedures of an object are the same for Feature Extraction. (See page 93.) In
this section, the differences between Rotation Adjustment (Feature Extraction) and Feature Extraction
and the way of testing are described below.
Feature Data that cannot be detected
With the Position Adjustment (Feature Extraction) function, you cannot detect the following feature data
except center of gravity.
• Perimeter
• Project Width
• Theta
• Area (but, Max. /Min. Area Limit functions are available. It is possible to perform sorting according to
the max. /min. area limit.)
When there are multiple objects fulfilling the conditions
When there are multiple objects fulfilling the conditions, be sure to perform sorting. The first object among
the sorted objects is detected. Sorting can be performed in the descending/ascending order of area, x
coordinate and y coordinate. If you do not perform sorting when multiple objects were detected, AX40
cannot detect the first object so you cannot perform a stable inspection.
Execution of a test
Before registering a base position, you can perform a test to check if Horizontal/Vertical Areas can detect
an object. When a live image is currently displayed, a test is performed after importing a new image.
When a Memory image is displayed, a test is performed with the Memory image currently displayed
without importing any images.
1. Select "POS. ADJ. (FEATURE)".
2. Press the A key while the tab or the item is highlighted.
If no edge was detected, the following error code will appear under the judgement results in the message
area.
D0044
Check to make sure that the error code above does not appear or the object is detected by using the
image.
In the following cases, Boundary is automatically set to "Off". You cannot change the setting.
• Inspection areas are circle or polygon in shape.
• Mask areas have been set.
• Labeling has been set to "No".
