Auto Fine-tuning

Auto Fine-tuning calibrates the target LiDAR to match more accurately with the reference LiDAR(s) without any additional information. This feature increases further the accuracy of a first manual calibration. It calibrates the target LiDAR most appropriately using the distances between the point clouds of the target LiDAR and the ones of the reference LiDAR(s).

Prerequisites

• Data coming from at least two LiDARs.
• At least one LiDAR is calibrated using Ground Alignment or Manual Calibration to be used as reference LiDAR(s).
• Rough manual calibration was performed to the target LiDAR.
• The actual overlapping region of 2 point clouds is large enough to find the optimal solution.

Steps

1. Click Tool > QuickTune > Auto Fine-tuning.

2. Select the target LiDAR that you want to calibrate.

3. Select the reference LiDAR(s) that you have already calibrated.

   - At least one LiDAR should be added as reference LiDAR.
   - *Note: the quality of the Auto fine-tuning varies depending on the overlap area between LiDARs*

   

4. Click "Launch" button when you are done with selecting reference LiDARs.

5. Calibration results will be shown. Make sure LiDARs are well-calibrated by clicking "Hold to show original points" button and comparing the changes.

6. Click "Apply" button to save the calibration result.
