I would like to take some images of the family farm throughout the season and compare the growth between certain areas.
I'm building my first aerial plataform, an Zagi 150mm.
- Turnyg 9x V2 + FrSky
- Tx / Rx 1.2Ghz 500mW
- Lipo nanotech 2200 3S 25C
- Turnigy 2210 250W / Proper 9x6e
- ESC 50A
- Sony CCD 1/3" HAD2 550 tlv
I think about a Nikon S3100 to do first test, first flights.
Good luck both!
I have a canon A480 with SDM
The easiest way to go is with a Canon Powershot so you can use CHDK. A2200 is a good very cheap camera that works well enough. The SX230 HS has GPS built in so you can get georeferenced results if you're interested in that. Check out some pictures I took with both at the address below:
Outstanding! What kind of setup was that? Height of 200m?
Thanks for sharing!
That platform is the E382, Skywalker airframe. Altitude was 100-120.
CHDK can read in pulses via USB (not PWM, only very long pulses in the tens of milliseconds long) so they can be triggered by the autopilot. I've done it before but it required modifying Arduplane code. There may be an easier way to link them up though with some PWM reading device that triggers the camera directly. I'm sure someone has made something like that.
Is there any post how to use CHDK with USB?
The main thing to make sure of is that the camera has a CCD sensor, not a CMOS one. Most consumer cameras do these days, but some don't, double check before you buy. CMOS sensors are subject to wavy images due to vibrations, this is much more noticeable in video, but still occurs in still images.
The Canon A2200 has been suggested. It is cheap and has a CCD sensor.
