Camera Range
Set the camera Range.
The narrower you set the camera range, the shorter the imaging time and
the sampling period become.
The default value is the entire camera range. (Sampling period: 5 ms)
Purpose of narrowing the
camera range
Narrowing the camera range has advantages such as those shown below.
(a) Shortening of the
measurement time
When you narrow the camera range, the sampling period will be shortened
by a corresponding amount.
This makes it possible to perform measurements on production lines that
move at faster speeds.
(b) Noise prevention
Depending on the workpiece profile and the environment, measurements
may be unstable due to the presence of noise and diffuse-reflected light.
Setting the camera area just to the measurement range can prevent the
influence of these elements on the measured results.
Diffuse-reflected light
