Ranger E Parameters
7.5.2 Horizontal Max (HorMax)
The Horizontal max component measures the range by using the maximum intensity. This
can be useful when the ROI contains several reflexes, but only the strongest reflection
comes from the triangulation laser line.
This component measures range data with less accuracy than Horizontal threshold, but
delivers an intensity profile as well as a range profile in each scan. The intensity meas-
urements are the maximum intensity value in each column – that is, the intensity at the
center of the laser line – and can be used for example for determining grayscale properties
of the object along the laser line.
The height resolution is 1 or ½-pixel, depending on whether or not sub-pixeling is used.
Parameter Description
Edit while
measuring
Enable Used for activating or deactivating this component in the
configuration.
0 = Deactivated
1 = Activated
Start row The first sensor row from which to acquire data.
Values: 0–511. Default value: 0.
Number of rows The number of rows to acquire algorithm data from.
Values: 16–512. Default value: 512.
Range axis Specifies whether to measure the range from the bottom
or the top of the ROI. Default value: 0.
0 = Highest value at top of ROI
1 = Highest value at bottom of ROI
x
Exposure time The time in microseconds during which the sensor is
exposed to light.
Values: 10–50 000. Default value: 5 000.
x
Laser pulse time Length of the pulse on the laser trigger output (Out2) in
microseconds.
Values: 0–20 000. Default value: 0 (no pulsed laser)
The pulse time must be shorter than the exposure time
and the cycle time (as set in the Measurement configu-
ration).
x
Pulse polarity Polarity of the laser pulse. Default value: 1.
0 = Active low
1 = Active high
x
Gain Factor to amplify the analog sensor data before AD
conversion.
Values: 1, 3, 4. Default value: 1 (No amplification).
x
Threshold The noise level – that is, the minimum light level to
consider as a valid laser position.
Values: 0–255. Default value: 10.
Note: a low setting of the threshold might increase the
amount of noise.
x
Sub pixeling The resolution to use when computing the mid-position
of the first and last position that represents the maxi-
mum value. Default value: 1.
0 = Resolution of 1 pixel
1 = Resolution of ½-pixel
Ad bits Number of bits to use when performing AD conversion of
sensor data.
Values: 5–8. Default value: 7.
