Hello,Im looking for images that contain plant in early stages to test out a plant counting algorithm. I know there are plenty PC algorithms out there, I just wanted to see for myself if it works.Thanks!

Hello to everyone,lastly I have bumped into a strange behavior after a few minutes of flight. I thought that the ESC were failing and changed them but the problem persist.Auto Analyzer says there are problems with the compass and other variables.…

"Indeed, it is pretty bad. A matlab algorithm was used.

What would you recommend?"

"It is English. A "net" is a piece of meshed fabric. Take a look at this video.

"Yes, I do use a retract lens camera. I think you are heading in the right direction. You can simply 3D print a protective cup.
Also, you could use a net to land/catch your UAV! I will start to build mine next week."

"That's a MTVI2 analysis for chlorophyll production.
It is quite easy when you have messed around a little while. Locate the GC of your flying wing. Get a brass tube with the same diameter of your camera's lens, heat the tube and make a perforation.…"

"Well, if you have the resources and don't mind what the learning curve implies then suit yourself.
About the payload, it depends on the quality of the information you want. Are you a farmer or a service provider?"

"You can "easily" modify a CANON camera to get IR and thus NDVI. You will not be able to get hydric stress or moisture index with an IR camera.
If you are not a professional or have any experience, I strongly suggest not to buy an expensive system.…"

"Glad it helped.
I do not have any exprience with the system you mention. In my opinion, what you should be the most careful when it comes to Ag UAVs are the cameras you are using.
What do you want to determine or know about the potatos with your uav?"

"Hi Roberto,
Potato crop is quite tricky! I have used a Fx-61 platform with an IR camera to do a couple of surveys with sweet results:

That's a 76 Ha potato crop with a central pivot irrigation system. I suggest you use a fixed wing if you are going…"
