SICK Ranger3

Data collection
DeviceScanType is set to Linescan3d.
The following settings are done automatically:
RegionMode[Region0] = Off
RegionMode[Region1] = On
RegionMode[Scan3dExtraction] = On
8.4.4 Maximum buffer size
The maximum size for an image buffer to be sent from Ranger3 to the host PC is
around 40 MB, and the maximum supported buffer height is 16383 profiles. The limit
is due to the limited GigE Vision retransmission buffer memory in the device.
The maximum buffer height (Height[Scan3dExtraction1]) depends on the data format, the
region width (Width[Region1]) and the number of enabled components (e.g. reflectance,
see "Reflectance", page 40). For example: With default settings, the maximum Height
is about 11000 profiles. When reflectance is enabled, the maximum Height decreases
to about 7000 profiles.
If the buffer size is maximized, the camera may block user actions that further increase
the size. Examles of such actions are:
•
Enabling another component, such as reflectance
•
Increasing the bit-depth of a pixel format
•
Increasing the region width
The user must decrease the buffer size to make the blocked actions available again.
This is done by changing the data format, decreasing the region width or decreasing the
number of enabled components.
8.5 Exposure time and measurement speed
Once the height of the sensor region is set, there are two other parameters that affect
the line rate of the camera:
AcquisitionLineRate The rate at which the lines in a frame are captured (Hz). Only
applicable when the camera is in free-running mode.
ExposureTime The time (μs) during which the sensor region is exposed.
The exposure time and the line rate are inter-dependent. The maximum exposure time
cannot be longer than the time between two profiles, minus about three microseconds
that are needed for readout and reset.
NOTE
The maximum exposure time and the maximum line rate are stored as floating point
values and rounding-off effects may make it impossible to set the exact value returned
by the GUI. The maximum deviation is 0.01 μs for the exposure time and 0.01 Hz for
the line rate.
8.6 Laser strobe output signals
The camera has two laser strobe output signals, LASER STROBE OUT1 and LASER STROBE
OUT2, see "Electrical connections", page 26. These signals are individually controlled
and can be used to control two separate lasers. You can use the signal to turn the laser
on only when it is needed, for example when two separate cameras and lasers are used
at the same time.
