Setting value Description
Hi-speed The search is performed at high speed.
Normal (default value) The search is performed in the normal mode.
Precision The position is calculated at high precision in sub-pixel units
(units smaller than pixels).
0 to 180° Sets in which angle range the model (rotated in degree units) is
(default value: 0) to be created. The smaller the skipping angle that is set, the
higher the precision becomes, however, the longer the pro-
1, 2, 3, 5, 10, 15, 20, 30°
cessing time becomes.
(default value: 10°)
When the rotation range and skipping angle have been
changed, register the model again.
OFF (default value) Calculates the angle in skipping angle units.
ON The angle is calculated as a numerical value down to three digits
past the decimal point based on the value obtained in skipping
angle units. Note, however, that the processing time increases.
This function is enabled only when the search mode is the nor-
mal mode or the precision mode.
0 to 100 Sets the level at which the model is searched for during a rough
search.
(default value: 60)
Images having a value of the degree of match at the candidate
level or more are taken to the candidate points in the Verifica-
tion. Set a lower level when the model cannot be searched for
stably.
0 to 255 Sets the level at which profile information is searched during
measurement.
(default value: 8)
Profile information is obtained from the change in light intensity.
Locations having a light intensity at the noise level or higher are
picked up as the profile. Locations having a lower light intensity
are judged as noise components.
Adjusting this level has the following effect.
OFF (default value) Measurement results are output using the camera's coordinate values.
ON Measurement results are output using the coordinate value
converted by the calibration function.
Normal (default value) The position information of the input image coordinate system
itself is output.
Pos. correction When position shift correction is set, the position information is
output using the coordinate system corrected to the original
state when the coordinate system was registered.
