USING DRONES FOR SAFER SURVEY AND MAPPING WORK ON TRANSPORTATION CORRIDORS

We recently tested our Structure from Motion (SfM) and Virtual Surveying approach in a road survey scenario. The only significant manual work in the field was to survey ground control and check points. Image acquisition (with a Pixhawk equipped quad copter and a 24Mp camera) as well as SfM processsing was a highly…

High speed scanning laser weighs just 75g and measures over 100m

We've been working on a laser scanner that is light enough to be carried by a small drone. Click on the image above to see a short video of the scanning action. This prototype is based on the SF30/C and an extremely lightweight motor drive. Four slip rings are carrying power, alarm and an analog image that is updating at 2000 readings per second. The unit gives saturated laser coverage to detect even narrow…
