Boresight Calibration

Boresight calibration is an important part of LiDAR integration because any uncorrected misalignment between the IMU and LiDAR frame will result in a less accurate point cloud.

Applanix LiDAR QC Tools precisely estimates the boresight misalignment angles between an Applanix IMU and a synchronized LiDAR scanner. No ground reference is required.

Trajectory Adjustment

Trajectory Adjustment is the correction of the GNSS-INS derived position and orientation based upon mismatches of overlapping LiDAR points. The LiDAR sensor itself becomes an aiding sensor to the GNSS-INS solution. The adjusted trajectory is used to produce the final LiDAR point cloud and to georeference any other imaging sensors (such as cameras). It is extremely powerful in GNSS-denied areas (e.g. urban or foliage area) and when using inertial sensors of lower accuracy.


  • Support for UAV and Land Mobile Mapping applications
  • Precise calibration of boresight misalignment angles between IMU and LiDARs
  • Smart Trajectory adjustment in areas of low accuracy to minimize processing times
  • LAS file generator
  • Automatic streamlined workflow in POSPac


  • Achieves the highest accuracy in georeferencing LiDAR and Camera data in GNSS difficult conditions
  • Accomplishes precise georeferencing even with low accuracy IMUs
  • Eliminates the need for re-work and ground control points
  • Results in substantial time and cost savings for georeferencing tasks.
