OxTS boresight alignment of LiDAR

Application Notes November 28, 2017

Automatic boresight feature for improved georeferencing

Works with OxTS GeoCloud georeferencing software

Produce stunning point clouds (PCD / LAS format) from a Velodyne LiDAR scanner using an xNAV and the OxTS GeoCloud georeferencing suite.

Aligning LiDAR and INS for maximum point cloud accuracy

GeoCloud includes a boresight alignment tool to achieve more accurate point clouds. This tool automatically aligns the LiDAR and INS reference frames using a proprietary algorithm analysing returns from two planar targets to find the precise alignment.

Save time, improve accuracy and reduce work-load

As well as saving time and reducing user work-load, the target-based system has been designed from the outset to be portable and simple to use in real-world applications. Two retro-reflective targets are arbitrarily placed on the ground (with no surveying required) and the vehicle is driven around these, during which time all the data required for boresight alignment is captured.

This figure shows planes of best fit partition by LIDAR azimuth, showing clearly the improvement when systematic boresight misalignments are removed.
