When processing mobile LiDAR datasets in ROCK Desktop , it’s important to select the correct trajectory and capture mode to ensure accurate results. This quick guide walks you through the proper workflow.
Step-by-Step Workflow
-
Import Your Dataset
-
Open ROCK Desktop and select your dataset from the USB drive or local storage.
-
When prompted, choose GNSS Trajectory — not SLAM processing.
-
This ensures the software uses GNSS positioning data collected during mobile capture.
-
-
Verify GNSS Connection
-
Confirm that your GNSS antenna was connected to the LiDAR sensor during data collection.
-
The antenna provides essential trajectory data for your mobile processing workflow.
-
-
Set Capture Mode to Mobile Vehicle
-
Scroll down to the Capture Mode dropdown.
-
Select Mobile Vehicle to ensure the dataset is treated as ground-based LiDAR rather than aerial.
-
This setting adjusts motion modeling and filtering for vehicle-based collection.
-
-
Validate and Process
-
Run the initial validation step to confirm your GNSS trajectory and base data are properly recognized.
-
Proceed with processing as normal.
-
Avoid selecting SLAM unless your dataset was specifically collected in SLAM mode.
-
Tip: If you accidentally process with the wrong mode (e.g., SLAM instead of GNSS Trajectory), your resulting point cloud may appear distorted or misaligned.
