Ranger E Parameters
7.5.4 High-resolution 3D (Hi3D)
The High-resolution 3D component measures range using an algorithm similar to center-of-
gravity. This component measures range with a resolution of 1/16
th
pixel, which is the best
resolution of the available range components.
In addition to range, the Hi3D component also measures intensity. The intensity meas-
urements are the maximum intensity value in each column.
The profile rate for the Hi3D component can be increased by binning the sensor rows two
and two – that is, the analog values from the same column of the two rows are added
before AD conversion. By binning the rows two and two, the component only needs to
perform half the number of calculations when determining the range. This increases the
acquisition speed, but decreases the resolution.
Parameter Description
Edit while
measuring
Enable Used for activating or deactivating this component in the configu-
ration.
0 = Deactivated
1 = Activated
Start row The first sensor row to acquire data from.
Values: 0–511. Default value: 0.
Number of
rows
The number of rows to acquire algorithm data from.
Values: 16, 32, 48, 64, …, 512 (other values will be truncated to
closest lower multiple of 16). 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 microsec-
onds.
Values: 10–20 000. Default value: 0 (no pulsed laser)
The pulse time must be shorter than the exposure time and the
cycle time (set in the Measurement configuration).
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
Ad bits Number of bits to perform AD conversion of sensor data on. A
lower number of bits slightly decreases the 3D resolution.
Values: 5–8. Default value: 7.
x
Enable
scatter
0 = Off – Range and Intensity only
1 = On – Range, Intensity and Scatter
Scatter
offset
Offset distance in percentage from the maximum position.
Too low an offset gives scatter value = intensity value, while too
high an offset gives a dark (black) image.
Values 0 – 50. Default value: 35
