Details Mode (Default):
When an object has projections or concave
surface, using this mode enables those edge
coordinates not to use for calculating an
approximate line. First, detects an approximate
line using all the edge coordinates, and then
detects the final approximate line only using
the edge coordinates in "Edge ratio used" from
those with a smaller error for the first
approximate line.
Select "Details Mode" to set "Edge ratio used".
2.
Select "Edge ratio used(%)".
The menu for setting "Edge ratio used"
appears in the upper left of the screen. The
screen window can be checked.
The "o" mark indicates used edges and the "x"
mark indicates unused edges. Set the value
checking the screen.
Default: 80 (%)
3.
Select "Execution Mode".
Default: "Speed First"
When selecting "Accuracy First", the inspection area is tilted to be at right angles to the detected
approximate line after the detection, and the approximate line is detected again. Compared to "Speed
First", detecting edges more accurately calculates an approximate line with less error. However, the
inspection time in "Accuracy First" is longer than the one in "Speed First".
Setting Base Angle
Select a base angle from the following four types for detecting the angle of the approximate line.
1.
Select "Approximate Line Detect Condition" > "Base Angle".
2.
Select from "X Direction", "Y Direction", "Rotation Adjustment Angle" or "Area".
X Direction
(Default):
Outputs an angle
regarding the position
at three o'clock as 0
degree.
Rotation Adjustment
Angle:
Outputs an angle
using Rotation
adjustment angle as a
base.
- The bold line (blue) is the approximate line.
- The above figures show the examples when Calibration Scale is not used or when Calibration Scale
is used and "Rightward - Downward" is selected for Coordinate Axis (positive direction).
Changing the setting of Coordinate Axis may change the value of the detected angle.
194
Y Direction:
Outputs an angle
regarding the position
at six o'clock as 0
degree.
Area:
Set the position of the
end point of the
inspection area to 0
degree using the
slanted angle of the
inspection area as a
base.
