Hi Sean 

 Yes i see that this is a common problem after updating to 3.1 i would think that 3dr would take care of the issue guess not. 

Thanks for the information i am going to try and go back to previous 2.9

I had the same problem, likely a blown regulator. seems a pretty common problem. In the "load Firmware" section of mission planner there is an  option at the lower right side that says "load previous firmware" or "load previous version" . You can find version 2.9 there.

hey guys 

Is it possible to go backwards in version say from 3.1 back to 2.9 my apm worked in 2.9 but came up with a problem in 3.1.

Thanks

Thank you all; I have making some progress towards my project while reading your inputs

@essam

You may have a look at this French site : http://airinov.fr/concept#/concept/télédétection

They are using 4 different lenses of which 2 different IR, specifically to do exacftly what you are looking for.

You may use Google automatic translation if you cannot read French.

@Essam: ArduCopter has no trouble at all climbing to 2200 AGL; in fact, it can get there very quickly.... the limiting factors here is regulatory and one of resolution and of vibration. As you are in the US, you'll need to stay under 400ft AGL. Being closer helps in that each pixel of your camera will cover a smaller bit of your target, meaning that it is generally more useful. It also means that whatever blur effect you have from high frequency vibration is a bit less destructive to the data, as long as it is within acceptable limits.

What is the reason you need to capture the entire area in a single shot (vs taking multiple shots in rapid succession using a patterned flight and stitching them together?) There are a growing number of software packages that stitch the photos together for you....

Comment by Sean Headrick on January 3, 2014 at 10:25am

@Essam As you are new to this technology, you may be overlooking the possibility of photo-stitching. In general terms this would allow you to take lower altitude, higher resolution images that could then be stitched together into a single flat image or into an actual 3D orthomosaic based on common points among the images or GPS tagging. It is still a pretty large area, but a fixed wing outfitted properly should be able to satisfy your requirements

I wouldn't say altitude is your problem until it comes to the camera resolution and filtering capabilities any craft given the amount of flight time required will perform the needed altitude and allow you the decent time to land too

 

to achieve the filtering required are there limits to distance to be effective ?

my concern is the farther away the less likely to get results usefull
