2-15-(23)
The direction of the line and the permissible range are set and only the lines
within that range are removed.
Correct measurement cannot be performed if the measurement object has
rotated. Therefore, if position displacement occurs, set position displacement
compensation earlier than the unit for which EC defect inspection is set.
Oriented Line Extracting Algorithm Using Edge Codes
1. An edge code image is created.
Points with edge codes within the permissible range are detected as edges
on the line.
Set the direction and permissible range.

Section 2-15
Lines with edge codes
within the permissible
range will be removed.
The defect is not within
the range and will,
therefore, remain.
