What are LiDAR QC Tools?

LiDAR QC Tools are a set of POSPac software tools developed by Applanix to achieve the highest level of georeferencing accuracy with LiDAR sensors. LiDAR QC Tools support boresight calibration between IMU and LiDAR sensor, trajectory adjustment and LAS file point cloud generation. Depending on the license purchased it either supports boresight calibration and LAS file generation or it supports all three components.

The LiDAR QC Tools creates Voxels (3D pixels) from the LiDAR data and matches these in overlap regions. It then runs an iterative least squares adjustment using the matched points to solve for the constant IMU boresight angles, and optionally makes corrections to the trajectory (position and orientation) used to generate the points. The boresight misalignment angles are ready to be applied in third party software with either the original or corrected trajectory file, or a new trajectory file can be exported with the boresights applied.

The software is hardware-agnostic and can work on any LiDAR system.

Boresight Calibration

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

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

The software is hardware-agnostic and can work with any LiDAR system.

Features

  • Precise estimation of boresight misalignment angles between IMU and LiDAR
  • LAS file generator
  • Export of boresight corrected trajectory
  • Trajectory adjustment based on overlapping LiDAR point cloud

Benefits

  • Precise geo-referencing of LiDAR data
  • Trajectory optimization by aiding LiDAR data
  • Trajectory improvement in difficult GNSS environments
  • Avoid point cloud mismatch
  • Embedded in POSPac workflow - no 3rd party software required and hence direct handshake

Purchase and Demo Options

Our completely integrated post-processing workflow in POSPac MMS or POSPac UAV makes it easy to run the tools automatically, with the push of a button. Our purchasing options mean you can use only what you need by choosing from our boresight-only or boresight and trajectory adjustment licences.
