Finally getting some decent results with my surveying drone:
It wasn't flying as nicely as desired, but I finally got the camera trigger working decently, so this is a huge step forward. The autopilot records when the camera is triggered and stores the GPS position, which is then later added to the EXIF data, which then greatly increases the speed and accuracy of the photogrammetry process.
It's taken about 6 months to get to this stage, so this is a huge milestone for me and it may enable me to just get the last month or so before harvest to do 'real' tests with.
Next up is converting the camera to IR,so I can do NDVI processing.
To celebrate this, I am now also building a freestyle/racing quad, so I can doing stuff like this :
