49 2D/3D Profile Sensors
Offset Z The integrated camera in the device has 1024 columns (MLSL) or 2048 rows (MLWL) in
the Z direction, which are read out continuously. As a default setting, offset Z has a value
of 0. If this value is increased, not all of the rows are read out, but rather only those as of
the new starting point.
Attention: In this case, height Z must be manually adjusted because it’s not self-adjust-
ing.
Height Z Specifies the total number of rows which will be read out in the Z direction. As a default
setting, all 1024 or 2048 rows are read out.
NOTE!
This setting reduces or increases measuring range Z.
Subsampling X Sets the number of measured values in X, which will be read out. This setting reduces
resolution in X but has no influence on the maximum profile rate – only network load is
reduced.
Profile Settings
Exposure Time Exposure time determines how much time the profile sensor takes for exposure at the
internal camera. This parameter also controls laser on-time. The value is specified in
microseconds.
Note regarding profile optimization:
At a signal strength of less than 10%, exposure time should be increased for an ideal
profile.
At a signal strength of greater than 90%, exposure time should be reduced for an ideal
profile.
Laser This function makes it possible to switch the laser on and off manually.
Measuring rate The measuring rate can be set when the “internal” sync mode is selected. The highest
possible measuring rate, depending on the selected ROI, can be found in the “ROI
Settings” section.
The formula for calculating the measuring rate for the MLSL is:
1 × 1,000,000 / ((0.003458273 × width X + 0.073443424) × height Z + 56)
The formula for calculating the measuring rate for the MLWL is:
149,359.496817005 × height
-0.8678007147
NOTE!
The measuring rate of the connected sensor is read out in the VisionApp Demo
3D software (DNNF013; can be downloaded for free at www.wenglor.com in
the product area) depending on the selected ROI
