SAE 2011 Autonomous Vehicle Symposium

Baker’s resident LiDAR Scientist, Dr. Srinivasan “Srini” Dharmapuri,  was a featured presenter at the Society of Automotive Engineers (SAE) 2011 Autonomous Vehicle Symposium, held at Carnegie Mellon University (Pittsburgh, PA) on 8/10/11. The symposium showcased smaller and more focused discussions on innovative drive assist and autonomous vehicle technologies in transportation, agriculture resource management, construction and mining.  Srini’s presentation conveyed the advantages and uses of Mobile LiDAR technology, and  highlighted several case studies performed by Baker in the Transportation arena , including roadway design, rail transit, and bridges.  The diverse group of international attendees included prominent individuals from the public and private sectors, as well as academia.

As Baker's resident LiDAR Scientist, Dr. Srini is responsible for application development, QA/QC methodologies, technical writing, improving processing efficiency and other related LiDAR (static, mobile and aerial) activities. As mentioned in an earlier posting, Srini is the Vice Chair of the ASPRS Mobile Mapping Committee.  Perhaps he can provide an update on the committee's activities in the near future.

 If you have a topic for Srini to write about, please leave it as a comment and we'll include it the Ask the Doctor series.


What is Mobile LiDAR?

Mobile LiDAR (Light Detection and Ranging) systems are comprised of vehicle-mounted lasers, cameras and GPS/INS navigation systems to capture highly-detailed and accurate three-dimensional (3D) topographic information for surveying and engineering applications. Michael Baker International became an early adopter of Mobile LiDAR technology by acquiring our first system in 2009, with further expansions in 2014 and 2015 that increased our fleet to four (4) Optech Lynx SG1 Mobile LiDAR systems. Over that period our systems have completed more than 300 projects throughout 29 different U.S. States (and multiple countries), and encompassing hundreds of thousands of miles. Our project portfolio includes applications in roadway design, 3D modeling, railroad corridors, signaled intersections, utility infrastructure, asset management, pavement condition assessment and airport infrastructure.
