9.4.6.7 Edge
[ 1 ] Edge Measuring Tool
Measure the edge in a specified window.
Use projection window (mode = 0 or 1).
Read 9.4.3.7 “Projection Window."
Edge measuring tool
Note: Windows that can be selected with the object window are those
where the edge can be measured (straight line, oblong {mode = 1,
0}, sector {mode = 1, 0}).
In
µ
Vision board, edge refers to a point at which an
object in the specified window changes from
darkness to brightness (black to white) or from
brightness to darkness (white to black).
The position of the edge detected by the µVision
board refers to a point at which the brightness in
the window or the area value meets the specified
level value. To specify the level value, an absolute
value or differential value is used depending on the
circumstances of the object. The absolute value
detects the position at which brightness or area
value passes a specified location. The differential
value detects the position at which variation of
brightness or area is greater than the specified
value.
