Hyperspectral imaging sees more than the eye
Hyperspectral imaging provides significant speed and accuracy in monitoring crop plants and vegetation, for example stress and disease detection in the field or in a greenhouse. Differences in the material composition and biological well-being of living plants can be accurately identified. For example, if a plant disease is found in one location in the field, the device will find the same disease in other locations where it might not be visible to the eye. The ability to detect and characterise plant diseases rapidly and in a cost-efficient way differentiates this technology from other technologies.
On a wider scale, hyperspectral imaging provides an effective method to monitor entire vegetation ecosystems. So-called Vegetation Indices calculated from the visible and near-infrared spectrum are commonly used to evaluate structural and functional traits in vegetation both qualitatively and quantitatively, which aids in estimating photosynthesis efficiency. These capabilities help improve the quality and safety monitoring in food production – in precision agriculture, for example, the findings can be applied to site-specific fertilisation or precise plant protection with pesticides.
“VTT brought vital algorithm and UI/UX knowhow into the project when we set the target to create an intuitive and easy-to-use user interface for the mobile hyperspectral camera platform.” says Harri Salo, Program Manager, Specim.
