Skywalker Drone Mapping Camera Setup with CHDK
"The trigger comes to about $17, not much difference from what you ordered. If I remember correctly, I chose the eflight because it also regulates the V to I think 4.5v...
Anyway, what you ordered looks fine and not too much more in cost. Let me know…"
Brenden replied to Peter's discussion Cameras for multi band imagery"Thank you for the thorough reply. I'll try the method you mentioned and report back. Based on what you said, maybe it won't be such a valuable improvement after all. Thanks again"

"The instructions for CHDK say to use a card reader. My sx230hs has a USB port. Is there an issue accessing the card directly in the camera?"

Have you tried the maxmax ImageJ macro for ENDVI? I really want to try it out. Would you share it?

What color setting is used? If…"

Drone set up / Goals / Current Status

Goal: Autonomous / semi-autonomous aerial mapping for creating georectified orthogonal imagery and eventually digital surface/elevation/terrain models (DEM, DTM). I'm in preliminary stages... though I believe that my POC is proven and so currently in testing and then on to my intended pilot…

Hey man,
I'm interested in purchasing an Arduplane w/ a U-Blox gps, and a 915 Mhz telemetry kit. I want to fly over an area and take a series of pictures.
Best case scenario:
I would like my set up to be able to...
- Have ground control software to autonomously fly over predetermined path throughout a 160 acre corn field. (graphing)
- Using a Canon PowerShot A4000 IS, take a series of pictures over this field every 2-5 seconds and be georeferenced.
- Use the series of photos and have software autonomously stitch the images together to give me one semi-seamless photo.
- Finally produce color, IR, and NDVI images from my stitched photo.
Any input on what plane, camera (if A4000 wont be applicable), stitching software, etc I would need to pull this off. Email me anytime if you like or on this site is fine. drewschlumpf@gmail.com
Thanks!
Best,
Drew
