![]() ![]() What is terrific about multispectral imagery is that this sensor technology can be used throughout the crop cycle. View damage to crops from farm machinery and make necessary repairs or replace problematic machinery.Make land improvements such as install drainage systems and waterways based on multispectral data. Measure irrigation. Control crop irrigation by identifying areas where water stress is suspected.Count plants and determine population or spacing issues.Help with land management and whether to take ground in or out of production or rotate crops etc. ![]() Provide data on soil fertility and refine fertilization by detecting nutrient deficiencies.Optimize pesticide usage and crop sprays through early detection. Multispectral sensor technology allows the farmer to see further than the naked eye.ĭata from multispectral imaging has the following benefits Viewing the health of soil and crops with the naked eye is very limited and is reactionary. Multispectral images are a very effective tool for evaluating soil productivity and analyzing plant health. Multispectral Imaging Agriculture Drones Benefits Of Multispectral Imaging There are also some terrific knowledgeable videos below. We also show you the latest multispectral sensors and which drones for farming that this multispectral sensors can be mounted on. In this article, we look at the basics of multispectral imaging technology, reflectance, wavebands and vegetation indices such as NDVI and NDRE showing you how this information gives the farmer terrific insights into the health of the soil and plants. This land telemetry, soil and crop data allow the farmer to monitor, plan and manage the farm more effectively saving time and money along with reducing the use of pesticides. The multispectral images integrate with specialized software applications which output the information into meaningful data. Multispectral camera remote sensing imaging technology use Green, Red, Red-Edge and Near Infrared wavebands to capture both visible and invisible images of crops and vegetation. There are huge benefits both to the farmer and to the wider environment by minimizing the use of sprays, fertilizers, wastage of water and at the same time increasing the yield of crops. Is it a cure-all for those pesky IR hotspots with some lenses? No, but it does help to greatly minimize them.Multispectral imaging camera sensors on agricultural drones allow the farmer to manage crops, soil, fertilizing and irrigation more effectively. Applied to the IR filter, this special coating is centered in the infrared band to helps alleviate reflections/hotspots. If you’re looking to do some false-color IR photography, 850nm is the wrong choice.Īnti-Reflective Coating. This conversion is for dedicated black and white capture. You’ll want to read up on shooting in IR and the post-processing required for the images.Ĩ50nm Produces B&W Images. For those of you who aren’t familiar with IR photography, the look is very different. Note: you may see front or back-focusing using autofocus under some lighting conditions. Try to shoot under indoor artificial lighting (not really any IR light there) and you’re going to need a tripod. Exposure times are similar to a normal camera when shooting in sunny conditions where IR light is abundant. You use an IR-modified camera just as you would a normal camera: autofocus works, live view works, and in-camera metering works. Instead of capturing three different colors of visible light, the camera now sees three different wavelengths in the near-infrared spectrum. The low-pass filter was removed and replaced with an internal 850nm infrared filter. ![]() We’ve had this Alpha a7R III modified for IR photography by the good people at Kolari Vision. ![]()
