Adventures in Aerial Image Stitching Episode #6

Generating survey area coverage routes

Update: 29 November, 2017:  The work described below has been connected up to the on board autopilot and tested in simulation.  Today I am planning to go out and test with an actual survey aircraft in flight.  I can draw and save any number of areas together as a single project (and create and save any number of projects.)  Once in flight, I can call up a project, select an area, and send it up to the aircraft.  The aircraft itself will generate an optimized route based on planned survey altitude, wind direction, camera field …

Celebrating the 4000th git commit!

Few people really know much about the AuraUAS autopilot system, but this post celebrates the 4000th git commit to the main code repository!

The entire AuraUAS system is hosted on github and can be browsed here:

AuraUAS traces it’s roots back to a simple open-source autopilot developed by Jung Soon Jang to run on the XBOW MNAV/Stargate hardware back in the 2005-2006 time frame.  I worked at the University of Minnesota at that time and we modified the code to run on an original 400mhz gumtsix linux computer which talked to the MNAV sensor head via a serial/uart connection.…

Notes

Here are a couple of comments about the flight.

The conditions were very windy and turbulent, but it was a long drive to the location so we decided the risk of airframe damage was acceptable if we could get good data.…
