    MAPIR cameras seem to be rather expensive for a cheap point & shoot camera with a $10 filter?

    Buy a P&S at Best Buy, visit Edmund Optics online. The post processing software is available free from a number of resources, you could get Pix4D's if you want something slightly better than open source stuff off the internet.

    MAPIR shows graphics of their filters spectral response, is this with a lens or without the lens, or are they just taking the word of the manufacturer that made the filter?

    Another issue here is that the imaging sensors are color. The sensors should be monochrome, that way you can use all available pixels on the sensor. All of these color sensors come in a Bayer Pattern. There are two green, one red, and one blue pixel grouped together. Therefore a 12mp Bayer color sensor with a red or NIR filter is using only 3MP out of the entire sensor.

    With a monochrome sensor, you would use all 12mp. This does not work if you mix all of the color pixels on a Bayer sensor to get a monochrome image, it has to be a sensor with no Bayer pattern.

    Your best bet for the cash strapped is to buy a consumer grade off the shelf Foveon(www.foveon.com) based Point & Shoot camera. The Foveon sensor has stacked photodiodes, not a Bayer pattern. You can pull data from each color layer individually, no need for filters, unless you want specific wavelengths? No need to worry about image stitching, the camera does it for you!

    I'd like to hear on this as well. Also, I'm working on fixing some positioning of my telemetry module on one of the aircraft-I lose telemetry within a small come directly in front of it. In that situation, will I be able to add GPS data to the .EXIF from the onboard data logs, since the telemetry file won't be accurate?

    Most 5.4mm GoPro replacement lenses are 10MP. 3 sec can be useful at the right speed and altitude so I personally think it's still on the table as a gopro substitute. Emailed them I will update with reply.

    Only 12MP and 3 sec per picture. Not really great specs for a dedicated mapping camera.

    @Mike T I am very interested in knowing this as well. Looks like the dual solo mounts are sold out so that means... something. I wonder if the fixed mounts account for the forward lean of solo while it's flying? If you find out more please post a blog. Cheers!

    Has anyone used these MAPIR cameras for NDIV mapping? Any possible issues ? I noticed they are just hard mounted, does anyone find a gimbal produces better results, or just allow enough overlap to alleviate any distortion?

    What would be a good equipment for NDVI + IR + Regular photo all in one so that i do not have to fly again and again for same area

    Heck I have some Long Wave Infrared cameras coming under $600 complete with f/1.2 lens. They are going to vineyards in drought areas so they can measure the stress on their grapes from the drought.

    What camera would that be?

  • Vega Tech Group LLC August 3, 2015 at 2:26pm

    GoPro's, again consumer grade cameras, not real good quality stuff, a bit over priced if you ask me for what you get. But hey, they have a marketing machine!!

    The Long Wave Infrared cameras would be excellent for firefighters, especially locating hot spots, people, wire inspection, in the field looking for animals that could be in danger, people in danger in areas that may be in a fire wake.

    There are uses in Ag for the LWIR cameras, but most is in the Visible and Short Wave Infrared(400-1700nm).

    Sure lets talk, send me a direct email:    kdbusto@vegatecgroup.com

    I will reply to set up a time and date.

    Ok, now the problem is allmost the standard. I would say Vega is right, maybe you are reachiching the lifetime of your sensor.

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?https://youtu.be/TDTW9TsvjZw 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…
