Since couple of time I'm doing some trials using a SX230 camera installed on a X5 wing.
The results seems to be ok, but I need to gain more trust :) that why I need your support regarding good sample pictures done by you.
To be more precise,please post some of your pictures, that you consider that are ok in terms of quality. If possible please point also the camera settings.
Here are some examples from me - 100m altitude (any advice is welcomed):
I'm a APM beginner and want to use a X5 with a digital camera.but I have no idea with how to start it
could you mind share your configuration file with us beginner,and talk about how to control a DC through autopilot
thank you very much.
Here you can find all my settings :
However I am not using APM but Gluonpilot v2.
Please let me know if you need more details regarding the setup.
Today I had an interesting experience, I have done a flight at around 12:00h , very sunny outside, and I have observed that on the majority of the pictures there is somehow a reflection of the sun. The flight was done over a wheat field.
What are the hours that you think that are the best for survey missions?
Try using a UV filter, you won't have this reflection. In my experience, the best times for survey missions are half an hour after sunrise and an hour and a half to two hours before sunset. At noon times, brightness of the sun is too high.
This is pretty typical backscatter or a hotspot for images of soil or vegetation. In remote sensing they call this anisotropic reflectance, or you can get into all the details by looking up bidirectional reflectance.
To avoid it fly earlier in the day when the winds are lighter anyway

Richard, thanks a lot for the sample picture , very good quality!
My big disadvantage is that my wing is flying at 60-70 km/h while taking pictures.
I will put on my Santa Claus wish list :) a hexacopter.
Practice stalls.... :-)
And be good for Santa.
Hi Alex, what setup you use on Canon ? What configuration you use for take this pictures with your X5 UAV ? Thanks !
I'm using as CHDK script this : http://chdk.setepontos.com/index.php?topic=10822.0
All the values are at default except shutter speed that is at 1/1600.
If you need more info let me know.
