What is a hyperspectral image?
hyperspectral image is a picture that includes the entire light spectrum. These images are usually used to find information that is invisible to the human eye. Some things, from oil to plant disease, do not appear otherwise using invisible light when shooting. This feature allows people to find trace amounts of substances simply through a photo rather than extensive testing. The process of creating a hyperspectral image is expensive, but is often cheaper than blind testing methods.
Light is just a small amount of light that shines on the ground. These other light belts, such as infrared or ultraviolet, are always present, but out of the reach of the human eye. Some substances look different under these lights if one could see them. These items can shine in strange colors or seem to excel, almost like a 3D picture.
By using a hyperspectral image, people try to make money on these qualities. Original use for thisThe technology was to find oil and minerals. Trace amounts of material in the soil would cause changes in invisible light spectrums. After using images to find probable places for natural resources, people could go inside and perform tests in specific areas. This eliminated the need for random or blind testing methods and both accelerated the process and reduced its costs.
technology has since moved to other areas and especially agriculture. By using hyperspectral image, things such as saturation and soil composition, as well as plant health, can be monitored. Plants absorb different waves of invisible light on the basis of their overall health; By monitoring this feature, the grower may notice the problem long before it is visible on the plant.
hyperspectral image consists of many layers of individual images; Each of them represents a specific frequences ofLight. These layers accumulate on top of each other and create cubes similar to the image showing the entire light spectrum. The strength of light emissions is obvious when browsing pictures, because stronger sources promote more frequencies.
This technology is very accurate and easy to use. The only real disadvantage of the hyperspectral image is the cost of storing devices and information. As these areas fall, hyperspectral imaging is more and more areas. This technology is already in certain areas of supervision and top construction, but the cost of decline creates use in medicine, domestic security and astronomy.
