LiDAR Calibration

Calibration of LiDAR data is the most difficult process to perform when developing LiDAR data. It doesn’t matter if you have any one manufactures type of system. Each system has its own characteristics. It doesn’t matter if it is the same make and model. The results from the sensors will vary. The inconsistent variable is Roll. Roll changes continually on most systems. Some systems hold calibration better than other but it seems the calibration needs to be checked continuously. The second most inconsistent variable is the pitch and then depending on system the scan factor error and pitch slope error. Typically, I have never seen a needed adjustment to the yaw once it is set by any manufacture. There are several variables that should not be adjusted in calibration or only adjusted by the manufacture. Typically, these variables will be provided by the manufacture. Comments regarding this subject are welcome.

New system technology

Leica announced at this ILMF 2010 conference that they would be introducing new LiDAR technology sometime this year. Optech announced the new Pegasus HD400. It will be interesting to see what Leica has to offer in relationship to the new Optech Sensor. Any additional comments or information on other companies technology would be welcome

LiDAR Server

Sanborn has recently deployed LiDAR Server. This application has been developed by Sanborn’s business partner Qcoherent ( http://www.qcoherent.com/ ) and has been tested over the last 4 months using Sanborn’s IT infrastructure. LiDAR server provides the following:

  • Serve LiDAR data on the web from your location or ours
  • Generate on the fly rendered products
  • LAS file delivery to desktop from Web
  • Easy client side customization through XML
  • Ability to QC LiDAR data over the web and tag edits

For more information please contact Sanborn www.sanborn.com
