Brakar,

Looks great! Is that EasyUAV again?

Comment by brakar on January 10, 2010 at 3:27pm

Thanks for the comment Chris,

Yes it was EasyUAV, as last time:
- Plane: EasyUAV/ FlexiPilot
- Camera: Canon Ixus 980 IS, (with CHDK installed, running script for remote trigging)
- Trigger: 5V current from Flexipilot to camera
- Picktures, In total 155, one shot each 40m, 14.7Mpix, (in tocal about 787MB)
- Radio: Futaba 7C
- GS, wireless link etc: not present

And finally, link to a short video clip:

Strange thing; the whole video was about 30minutes and 660MB. When I exported a short 1min clip in reduced quality it ended up at 275MB !

Nice competition and a good try brakar!
Hope it gets a little milder here soon so I can get back in the air again...
I will have a new UAV for the 2010 season...

Reduced quality is always costly ;-)

I could not help myself for making one more attempt. About the same track as last time, but take-off was on the far side. This time I had no problems with the zoom and got 153 beautiful picktures - wich stitched quite well in PTGui, (no need for adding extra control points). Just a few distortions and missing areas in the finished stitch. I did also try the MS ICE freeware (thanks for hint Gary) for stitching. Stitched very easily, but output-file was 550MB TIFF, which I don't have software to reduce.

KML: trace.txt.trace001.kml

Here is a reduced PTGui panorama. The original file is close to 28MB, so I will wait with uploading until see if I can make a geo-referenced to GoogleEarth.

By second thought, here is the whole stitch, don't know if I will have time to finish it due to work/travel activities. There was not anything in the rules saying it should be linked to GE I think

WARNING: 28MB

Original picture (proof of concept), it is in the stitch as well

And kmz-file for geo-ref. in GoogleEarth, (big thanks to Krzysztof): AskerMap.kmz

This is my preliminary entry using EasyUAV:
the battery died too fast and the plane automatically returned home (miscalculated battery state, making too many flight pattern tests earlier, without the camera).
Used Microsoft ICE without effort as the photos were almost perfectly aligned.
CropScan.kmz
This post is scanning only half of the surface and there is no Santa Claus around, so formally insufficient but IMO worth sharing. Made Dec 27th last year, just after the snow has melted.

My old AXN Floater airframe was getting pretty beat up and I was having some radio problems so I decided to build up a fresh floater and install a 2.4 GHz radio system. here is a test run that was supposed to also include images, but when I got out to the field I realized I had the wrong firmware loaded (no trigger function). So this was a test run of a new airframe, new radio and new cross track code. Overall things went pretty well. We have some weather moving in, but I hope t get out in the next day or two and repeat the run with the camera on board.
