SETTING THE MEASUREMENT CONDITIONS

Detailed settings (if necessary)
When measurement is not stable, adjust the detailed conditions.

Setup Item Setting value Description
Search mode Hi-speed Matching is performed at high speed.
Use this mode to shorten the processing time.
Normal The search is performed in the normal mode for both speed
and precision.
Use this mode to measure large text or roughly drawn pictures.
Precision (default value) Positioning is performed at high precision followed by match-
ing.
Use this mode to measure fine text or detailed patterns.
Sensitivity Low
The model is subdivided into nine models of up to three divisions in
each of the horizontal and vertical directions and then measured.
Middle (default value)
The model is subdivided into 25 models of up to five divisions in
each of the horizontal and vertical directions and then measured.
High
The model is subdivided into 100 models of up to ten divisions in
each of the horizontal and vertical directions and then measured.
Rotation range 0 to 180°
(default value: 0)
Sets in which angle range the model (rotated in degree units) is
to be created. The smaller the skipping angle that is set, the
higher the precision becomes, however, the longer the process-
ing time becomes.
Skipping angle 1, 2, 3, 5, 10, 15, 20, 30°
(default value: 10°)
Interpolation 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 normal
mode or the precision mode.
Verification OFF (default value) The search is performed in detail near a candidate point having
the highest correlation value.
ON The search is performed in detail near all candidate points.
Select [ON] when the model cannot be searched for stably.
Candidate level 0 to 100
(default value: 60)
Sets the level at which the model is searched for during a rough
search.
Images having a correlation value at the candidate level or
more are taken to the candidate points in the Verification. Set a
lower level when the model cannot be searched for stably.
Solid color check OFF (default value) Select [ON] when inspecting sections of solid color on subdi-
vided models.
ON
Output position Most dissimilar part
(default value)
The center coordinates of the subdivided model having the low-
est correlation are output.
Center position The center coordinates of the model that was found are output.
Calibration 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.
Coordinates mode 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.
