Angle detection
You can detect the angle of an object by selecting 1P-SCH (1-point search) in the POSI-DEVIATION
item (measurement 0 to 4) .
(1) Angle detection by object shape
There are some objects whose angle cannot be detected, due to the shape of the object and the
compression level used for the gray scale search, as shown in the table below.
Object shape
- The information given above is true when the measurement conditions are as follows: the size of
the reference image to be registered is approximately 64 X 64, and the search size is approximately
100 X 100.
(2) Setting method
On the [TYPE MEAS COND] menu, select the "1P-SCH" or "1P-SCH+1P-EDGE" mode and then
select the "3DTECT ANGL" item. - See page 4-2.

1. Select the "1P-SCH" or "1P-SCH+1P-EDGE" mode.
2. Select the angle search range (±15˚, ±30˚, ±45˚, ±360˚) on the "3DTECT ANGL" item.
The larger the angle search range, the slower the processing will be.
3. Select a rotation step size in degrees in "4ANGLE UNIT," using the up and down keys.
The relationship between the detection range (unit) of the rotation angle and the reference
images to be created is shown below:

Angle detection
The angle cannot be detected.
The angle can be detected using a
compression level of 2 for the gray
scale search.
