Crop Duster Hex Copter

Started by Steve Burton. Last reply by Steve Burton Aug 4. 3 Replies

I have been working on a crop/golf course dusting Hex AgCopter. I am using a DJI S800 with DIY APM as the controller. We did some preliminary test using a simple spray rig to test the feasibility. It…Continue

How many Precision Ag UAS/UAV firms are there now?

Started by Eric Kubicka. Last reply by Michael Leasure Aug 3. 3 Replies

I am curious as to how fast this sector is growing (given the known FAA constraints). Any data points? Even if anecdotal it would be good to hear. I have come across about 10 to 12 North American…Continue

We had the opportunity to head out to Illinois last week to get one of our drones into the hands a company that some test plots and to set up a booth at the inaugural Precision Aerial Ag Show (PAAS).…Continue

Canon S110 Infrared performence

Started by Neil Yu. Last reply by Jeffrey Warren Jul 16. 6 Replies

Hi, I plan to modify the Canon S110 to capture IR image only by replacing the internal filter with a 720 nm long pass filter. I am wondering if anybody has experience with that and how is the image…Continue

Hi .. Name Leo Currently Sanae Base Antarctica. Transforming Electric Glider to Drone. Saw same requirements in NAM few months ago. Like to get involved.

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.
