What is hyperspectral remote sensing?
Hyperspectral remote sensing is the science of acquiring digital imagery of earth materials in many narrow contiguous spectral bands. Hyperspectral remote sensing combines imaging and spectroscopy in a single system, which often includes large data sets and require new processing methods.
How many bands are there in hyperspectral?
Hyperspectral data sets are generally composed of about 100 to 200 spectral bands of relatively narrow bandwidths (5-10 nm), whereas, multispectral data sets are usually composed of about 5 to 10 bands of relatively large bandwidths (70-400 nm).
What is NIR hyperspectral imaging?
Overview. Hyperspectral imaging is a chemical imaging technique based on reflectance spectroscopy (the light reflected by materials). Near Infrared hyperspectral imaging is a non-invasive, in situ technique that allows to collect data cube in few minutes without any preparation of the artwork.
What are the uses for hyperspectral imaging?
Precision Agriculture. Resonon’s hyperspectral imaging systems are used in agriculture research all over the world, enabling identification of weeds, monitoring of plant health, and evaluation of ripeness. Early detection of crop stress is a common application.
What is hyperspectral imaging (HSI)?
Hyperspectral imaging (HSI) measures these reflectance properties to observe distinct features or to measure changes. It can help researchers locate objects, identify materials or detect processes. It can tell scientists the composition of a reef and how the organisms are dispersed.
Why choose resonon’s airborne hyperspectral sensors?
Resonon’s airborne hyperspectral sensors are completely integrated turnkey solutions, with all the hardware and software necessary to acquire georegistered hyperspectral data. Systems can be fitted with any of Resonon’s hyperspectral imaging cameras, covering the 350 – 1700 nm spectral range.
What are the modes of hyperspectral imaging?
Figure 1. Different modes of imaging illustrating the benefits of hyperspectral imaging. Hyperspectral imaging (HSI), or chemical imaging (CI), is the combination of spectroscopy and digital imaging. A spectral image contains many spectra, one for each individual point on the sample’s surface.
What is a hyperspectral camera?
A hyperspectral camera is the integration of an imaging spectrograph with a monochrome matrix array sensor (camera). The basic building blocks of push-broom hyperspectral cameras are shown in Figure 2. Figure 2. Hyperspectral camera schematic showing basic building blocks of push-broom hyperspectral cameras.
