Key Points for Test Measurement and Adjustment (Scan Edge Position)

In addition to the camera input image, the measured region, a graphic display of the measured results, and the edge position (the crosshair cursor) are also displayed as results in the Image Display area.
Explanation of the display of scan edge position
The following content is displayed in the "Detail result" area as text.
Displayed items
Description
Judge
Judgement result
Peak edge position X
X coordinate of the edge that is the furthest from the start point of the measurement region
Peak edge position Y
Y coordinate of the edge that is the furthest from the start point of the measurement region
Bottom edge position X
X coordinate of the edge that is the closest to the start point of the measurement region
Bottom edge position Y
Y coordinate of the edge that is the closest to the start point of the measurement region
Edge position X Ave.
The average of X coordinates of all the edges
Edge position Y Ave.
The average of Y coordinates of all the edges
Long distance Max.
The maximum distance between the approximate line and edge position (plus direction)
Short distance Max.
The minimum distance between the approximate line and the edge position (minus direction)
Deviation
Deviations in concavity and convexity
Line angle
The straight line's inclination against the measurement region does not include 180, which is displayed as -180.
Lost point count
Number of parts for which the detection of edges has failed

Key Points for Adjustment

Select the adjustment method referring to the following points.
When the measurement results are unstable
Parameter to be adjusted
Remedy
Measurement
If the color of the edges to be detected is decided, specify the color with [Edge color].If results are not stable even with the color specified, specify a larger value for the color variance range.
If noise is detected as an edge, specify larger values for "Noise level" and "Noise width".
