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.…

Image Stitching Tutorial Part #2: Direct Georeferencing

What is Direct Georeferencing?


The process of mapping a pixel in an image to a real world latitude, longitude, and altitude is called georeferencing.  When UAS flight data is tightly integrated with the camera and imagery data, the aerial imagery can be directly placed and oriented on a map.   Any image feature can be directly located.  All of this can be done without needing to feature detect, feature match, and image stitch.  The promise of “direct georeferencing” is the ability to provide useful maps and actionable data immediately after the conclusion of a flight.

Typically a collection of overlapping images …
