Multispectral & Hyperspectral Imaging

Multispectral & Hyperspectral Imaging

1 Hyperspectral images collect information across the light spectrum including the parts of it that are not visible; the information is collected in information “cubes” formed by many layers, each an image of same scene in different wavelengths. Hyperspectral imaging can be used as a chemical sensor and allows object differentiation and classification by differences in their chemical composition. Hyperspectral images are formed by thousands of spectral layers of the same scene or object and its spatial coordinates.

2 We have customized this technology to be used in agriculture and particularly to identify crop pests and diseases such as plant viruses, bacterial or fungal diseases, insects, etc. Main objective of hyperspectral imaging in pest and disease management is to identify the target pest or disease before it causes crop damage.

3 Using this technology, EKOFASTBA can identify mineral sources not visible from land surface, by detecting the spectral footprints which define certain types of compounds.

4 Hyperspectral images are also useful to generate digital terrain models (DTM), which can be used for multiple applications, such as determining flood areas on a river, based on the waste silt or organic matter from previous flooding.

The following demo shows a direct application of multispectral imaging for agriculture.
