Red Filter!!!

NIR images in itself does not contain all the parameters required for further processing. We need to install an additional filter to alienate unnecessary parameters and allow the entry of only necessary spectrum. The camera sensor is designed in a way that it distributes all the spectrum received into three bands of Red, Green and… Read More Red Filter!!!

Multi-Spectral cameras required to take NIR images for crop analysis

There are many cameras in the market ranging from digi cams to high profile DSLRs. But we require cameras that can capture NIR images of the plants which contains the required data for crop analysis. There are many cameras in the market which provides the capability to capture NIR images. I am going to show… Read More Multi-Spectral cameras required to take NIR images for crop analysis

Role of SWIR(shortwave infrared) to reveal details used in crop analysis

What is Shortwave Infrared(SWIR) Imagery? SWIR refers to a non-visible range of light falling between about 1400 and 3000 nanometers in wavelength, outside of the visible range. Due to the unique properties of minerals, man-made material, and other features, SWIR imagery can “see” objects in a way that is invisible to the naked eye and… Read More Role of SWIR(shortwave infrared) to reveal details used in crop analysis
