Day 2 ILMF 2014 #ILMF14

I had an opportunity to compare two lightweight LiDAR sensors today that are both candidates for the UAS platforms that everyone is talking about. The first is the Velodyne HDL-32E which weighs only 1 kg, sells for under $50k and can collect 700,000 pts./second.

The second is the Riegl VUX-1 which is being offered as the first survey-grade UAS laser scanner. This unit weighs slightly less than 4 kg and can collect up to 500,000 pts./sec. The price for this unit has not been announced.

I also had a briefing on the Leica AHAB Chiroptera, a combined topographic and bathymetric LiDAR system for near shore applications. This system also includes an RGB camera and can be used with a gyro mount. This systems sells in the range of $1.5 million Swiss francs and represents some of the most sophisticated LiDAR technology on the market.

    It would be great to see the VUX-1 in action,and take a view the results in a point cloud or something

  2. Not sure about the 4kg Riegle flying, but the 1kg Velodyne HDL-32E with 32 laser beams and 700,000 data points per second took off on a UAV by during a spontaneous event during ILMF….watch the UAV collecting live data and transmitting it wirelessly to the real-time viewing and recording program VeloView ( on the computer.

    XactMaps will process this data taken without GPS or IMU to get a geo-referenced point cloud. Stay tuned for the update.
