STEP 2: Setting the Direction
Set the line direction and the permissible range for oriented lines to be
detected and removed.
There are two methods to register the settings.
HELP
Line Directions and Angles
Locations where the brightness changes are detected as edges and the direc-
tion of the change in brightness is found. This is called the edge code and it
indicates the direction of the line. The arrangement of black and white deter-
mines the edge code direction, and angles are calculated as shown below.
Method Contents
Input figure The measurement object is displayed and arrows are placed on it
to set the direction and latitude of angle.
Input parameter The direction and latitude of angle are input numerically. In the
background, an image with lines removed corresponding to the
angle settings is displayed.
Set line direction and
permissible range.
Example
Only this edge direction is outside the
permissible range and is, therefore,
detected as a defect.
