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…Continue

"I looked at your log file,  it looks like you are losing RC signal sporadically hence its swithcing between flight modes AUTO and ALTHOLD...check your TX/RX setup, something isnt right there...."

Strange behavior during flight (Hexarotor)

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. Nevertheless if you manually review the log you will find that everything works well until minute 6-7. This has happened in 4 flight attempts after making sure everything is calibrated and well adjusted.Hopefully someone more experiment than myself can…See More

"Indeed, it is pretty bad. A matlab algorithm was used. What would you recommend?"

"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."

"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…"

"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?"
