Hi all,
A found about CHDK several month ago, and now I just finished writing my first scripts. I don't know who to thank, but still: thank you :-)
Now, here is my application: I have a UAV (radio controlled plane with a
gluonpilot.com autopilot on-board). I can send remote triggers to my Ixus120 from this autopilot. So I want to make photos (about 2seconds between every photo to make sure they overlap) in a way that I can later assign correct GPS coordinates to it. Currently, this is how I plan to do it:
- Send a trigger from the autopilot to CHDK
- Save the GPS-coordinates at each trigger in a logfile on the autopilot
- After the flight, post-processing can be done
Now the questions:
1) How can I make sure my camera can trigger every 2 seconds (or less)? Right now I manage to send a trigger about every 4 seconds. Focus is always infinity, ISO value and shutter time will be more or less constant over the flight. Right now the script is as follows (obvious parts skipped):
shoot:
press full_shutter
sleep(200)
release full_shutter
press half_shutter
How can I increase the trigger speed here? I tried setting focus at infinity, but the speed remains more or less the same. When I manually do the triggering (never completely releasing the shutter), I can trigger about every 2 seconds or even faster.
2) If you guys (with all your experience) have a better idea about how to do this, please let me know :-)
Thanks!
