SDL: Software Defined LiDAR Parameters
Understand the SDL parameters for the Carbon 30 LiDAR and how to adjust them.
The Voyant Visualizer gives access to Software Defined LiDAR (SDL) parameters that allow the Carbon 30 sensor’s point cloud data to be tailored to fit the needs of the use environment, desired output resolution, or visualization purposes.
SDL parameters are only available through the Voyant Visualizer when a live Carbon 30 LiDAR sensor is connected.
The SDL parameters can be adjusted to affect the sensor’s:
- operating state
- field of view
- frame rate
- waveform parameters
Available SDL Parameters
Read below for a description of the available SDL parameters and how changes in their values can affect the Carbon 30 point cloud.
Note: Not all SDL combinations are supported. If a selected combination is invalid, the Voyant Visualizer will display an error after attempting to apply the parameters.
Ramp BW (GHz)
Ramp bandwidth (BW) controls the tradeoff between the range precision and maximum range of the sensor.
- Higher bandwidth improves range precision.
- Higher bandwidth reduces maximum range.
Use a higher Ramp BW when short-range precision is more important than long-range detection.
Frame Rate (fps)
Frame rate sets how many times the sensor scans its field of view per second.
Increasing frame rate may reduce the number of column samples per scan, which can reduce angular resolution.
- Higher frame rate increases scan frequency.
- Higher frame rate reduces the number of column samples per scan.
- Fewer column samples lower the sensor’s azimuthal angular resolution.
HFOV (°)
The Horizontal Field Of View sets the angular span (in degrees) of the sensor.
The maximum HFOV is 120°.
- Higher HFOV provides wider scene coverage.
- Higher HFOV lowers the azimuthal angular resolution.
