OxTS Georeferencer provides mapping professionals with an effective yet straightforward method of georeferencing LiDAR data.
The software includes an optional boresight calibration tool that aligns the coordinate frames between a GNSS/INS and LiDAR to remove blurring and double-vision – improving the clarity of results.
Released today, OxTS Georeferencer 2.8 sees the introduction of a new target-less boresight calibration method giving users more flexibility when deciding how to calibrate the angle offsets between their LiDAR and GNSS/INS.

New boresight calibration options!
With OxTS Georeferencer 2.8 users now have the ability to choose how they boresight their GNSS/INS and LiDAR payload.
The traditional target-based method, requires a user to survey two dedicated, physical boresight ‘targets’ at varying speeds and angles. The collected data is then used to calculate the angle offsets between your GNSS/INS and LiDAR.
The new target-less method, available in OxTS Georeferencer 2.8, removes the need for physical hardware targets, and so to the space required to survey them.
Both methods remove blurring and double-vision from point clouds and improves overall accuracy.
How does target-less boresight calibration work?
The new target-less method works simply by using the surrounding infrastructure to act as boresight targets. The process is very straightforward:
- Choose a flat planar surface. This can be a wall, road sign or even the ground.
- Drive or fly your LiDAR payload over, or near to, the surface at varying speeds and if possible, angles.
- Open OxTS Georeferencer.
- Upload NCOM and PCAP files created by your GNSS/INS and LiDAR sensor.
- Click ‘run boresight calibration’.
OxTS Georeferencer will then accurately calculate the angle offsets using the data you’ve collected.
What else is included in OxTS Georeferencer 2.8?
+ New custom LiDAR decoders – If you want to use OxTS Georeferencer but your LiDAR isn’t listed as a supported sensor, don’t despair! A new custom LiDAR decoder format, now included in OxTS Georeferencer 2.8, allows you to integrate your sensor without having to wait for a new release!
This added flexibility means the GNSS/INS and LiDAR combinations you can use with OxTS Georeferencer really are almost endless!
+ Ouster custom packet format – OxTS Georeferencer 2.8 will now also include a new Ouster LiDAR custom packet format making it easier than ever before to integrate newer Ouster devices into OxTS Georeferencer.
+ Usability improvements – As well as making it easier to integrate new LiDAR sensors into OxTS Georeferencer, version 2.8 includes some important usability improvements, these include:
- Output information regarding waypoints has been filtered out.
- Reduced NCOM load time.
- Improved memory allocation for Boresighting – higher channel LiDARs are now easier to boresight.
Remember, you don’t have to use an OxTS GNSS/INS to take advantage of the boresight calibration and georeferencing tools in OxTS Georeferencer. Using the anyNAV feature you can use your existing navigation device alongside your LiDAR sensor.
