  • Mario, A lot of chromatic aberration in that image. A good lens for UAV's will not need to be refocused. You can set it and get clear images no matter the height over the object.
  • Thanks Mario! Looks good, it is a bit blurry.

    Still trying to get the focus right, but here is a single image from the MAPIR over a stubble field. 

    Blurry, but getting better. It's a lot of trial and error to get it set for 118m. 

  • I just posted a long-winded discussion "The right tool for the job" to throw my thoughts of this recent discussion into the ring. I welcome feedback and comments.

  • Is it just me or anyone else finding it difficult to follow all these conversation on the comment wall on this group? Why don't we create appropriate threads in the forum which makes it easier to follow..?

  • Index in NDVI is a set of numbers assigned to various aspects of what is radiometrically imaged from water to green plants. Originally used to determine green plant viability.

    A single sensor can be used but a monochrome would give the best results allowing utilization of the entire sensor. However well designed multi sensor cameras will provide faster and more accurate results.

    I have used machine vision cameras to also inspect and sort food for a number of years.

    There are a number of indexes to determine food health & viability.

    Currently some vineyards are using LWIR to determine the water content of their grapes.
  • Well, lets have a conversation about what the differences between these systems might be.

    I'll volunteer to put my neck on the chopping block and start that conversation............

    My understanding is this maybe something like.

    1. What 'index' means in NDVI or rather wraping some numbers around our data to obtain a value of variance?
    2. Can a single sensor system, with or without a Bayer filter, ever give anything that could be called an index?
    3. Would an agronomist base a decision on $M1/2 worth of cotton using data from a $300 sensor or is this type of thing more of a (potentially useful) general crop heath scouting tool?

    I think the potential conflict here is some people are talking about point 2. above and some are talking about point 3.

    Any one care to reply? (Neck still on the block and I'm sweating now!!)

  • I am not selling anything. I am offering information that will eventually trickle down to this market, 10-15 years from now. MAPIRS imaging is what I worked on about 15 years ago.

    My newest Visible/NIR/SWIR lens covering 400-1700nm is $1800. No one here can afford one, however it is in a design in to replace the PVS-14. It will trickle down this market in 10-15 years.
  • You have to understand that many are starting out so budgets are tight. No one is saying the stuff you are selling isn't of higher quality. If a person is well established I am sure that they would be happy to invest in such equipment and maybe even better. It's like trying to sell an Arri to a student filmmaker. It is a waste of time for both involved. 

  • Open your mind! (and your wallet)

Hexa with Hobbywing X8 motors

Hii am building a hexacopter with1.) hobbywing x8 motors2.) flight controller pixhawk PX53.) battery 12s 22Ah4.) wheel base of around 1800mm5.) estimated weight around 17kg without payloadi am looking if anyone has already tuned this type so i can get a head start. looking forwardthank youMike

What are the impacts of agricultural drones on the agricultural development of various countries?

Agricultural drones have gone from being questioned by the market to being actively promoted by the government, from tens of thousands to thousands of dollars. Behind this is the rise of technology in the entire industry. However, the degree of promotion of agricultural drones varies greatly in different regions. What do you think of the application of agricultural drones in your country? EFT agricultrul drone solution

Open Source Drone Payload Project Supporting In-Flight AI

I'm leading a project to develop a completely open source system for deploying artificial intelligence and computer vision on a drone. We are trying to make the system as general purpose as possible, but one application would be supporting precision agricultural. The real-time, in-flight processing aspects of the payload are probably less interesting for precision AG, but the data collection and curation capabilities might be. We are getting started with a few specific missions, we are…
