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 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.
POSPac Mobile Mapping Suite, now with POSPac Trimble Post-Processed CenterPoint® RTX™ (PP-RTX), is Applanix' next generation, industry-leading software for Direct Georeferencing of mobile mapping sensors using GNSS and inertial technology. It is optimized for all environments and platforms (air, land, marine) and compatible with a variety of mapping sensors. This smart software solution achieves both maximum accuracy and maximum efficiency for Direct Georeferencing.
