What software are people using to stitch photos together?

I am new at this, and so far have not been able to determine what software is being used or recommended.  Most of the software I find is either to do panorama's or heavy duty 3D.  I assume Agisoft…Continue

To Milan, we are actively doing research on toxic algae blooms at Kansas State University, including the determination of algae density using small unmanned systems. This video demonstrates such a flight:

The video was shot at a site where we have a COA.
The coverage is limited by the duration of the aircraft and the typical regulatory restrictions of flying line of sight.

Milan, the algae was NVDI using a Sony cybershot with custom filter and lense. Really big and heavy cam, old tech, but cheap. That was done about 7 years ago. The study was of the rain runoff and its impact on the bloom. I don't understand your question on the 40 acres. The camera captures that much acreage per photo and they are patched together back at the office. The critical issue was that the photos be straight down and not angled at all. This required piezo gyro stabilization back in the day. Now the ardupilot can take care of that. In actual field deployment, simple equated to flexible and reliable. I know this is bad news for the robotics, autonomous types but we found a GPS downlink to a laptop, stabilization gyros, and a manually triggered camera worked most reliably. More autonomy than that and we were fighting the glitches, wind, radio links, etc. i am not yet convinced autopilots and automated camera track and triggering are needed or reliable. We continue to test and modify but often uncover weaknesses in field use. Keep it simple and build on that.

Hi Micheal, I would like to become more involved in this field it interests me. Regarding algae blooms do you use NVDI? Also is the monitoring of these purely for the benchmarking of treatments? Also 40 acres is 0.2km^2 and this entails whats kind of flight path? Is it perimeter or sectional?

To Milan below, we have flown algae blooms, 3D model generation of micro topography using images, marijuana detection, stress in mint crops, drought damage, underground tile location, effects on bio mass with and without fungicide application for Monsanto, effects of weed shading on new plant growth, and several generic health evaluations of corn and soybean crops. We do 40 acres at a time, IR and color. Purdue University is a leader in image processing, regardless of the source of the image.

Yes, the image processing has been commercialized for decades. Satellites and light aircraft have created a well worn path for us to follow in agriculture. The primary advantage of a UAS platform is quick deployment, operation below cloud decks, resolution, and immediate access to photos. AGS Brazil bills UAS at the same rate as manned aircraftvso cost savings are something yet to be realized.

Is there anything happening to commercialize this technology?  e.g. offering  real time image analysis services for farmers ?  I would be interested in the  current status, thanks.

Hi Scott, what airframe / platform are you using for all that? Plane or 'copter? I'm curious about your setup. Thanks for any info. - Jim

Comment by Scott M Brown on December 13, 2013 at 1:25pm

Both, we fly a sony nex5 for EO and a TetraCam ADC Micro for NIR NDVI images on the same flight. To give both perspectives to the farmer.

HI

What are the fundamental needs of an agriculture UAV? (ie. Would it be purely a aerial perspective, or the post image processing)

Comment by Michael Leasure on October 6, 2013 at 12:42pm
Is anyone using the IR lense system on the gopro for ag applications? Have a research partner interested in downsizing our entire platform for ease of launch and recovery. Topviewuas.com
