6.14 Position Adjustment (Feature Extraction)
6.14.1 Setting Procedure
The procedure for detecting and setting the object is the same as that for "Smart Matching". (See page
93). In this section, the differences and notices are described below.
The items that cannot be set with this feature
The Position Adjustment (feature extraction) function does not detect the following feature data except
the 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 matching 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. Refer to page 103 for sorting
function.
Testing
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.
E0044
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".
