Accurate sensing system combining geometric information with spectral data

Hyperspectral imaging is a form of spectral imaging wherein information from across the electromagnetic spectrum is collected in many narrow spectral bands and processed. As such, information of the objects that are imaged can be derived. As objects leave unique spectral signatures in images, information regarding the presence and/or status of objects in a region that is imaged can be obtained. Detailed prior knowledge of the objects is not required.

Multi-spectral data are often obtained by collecting multiple two dimensional images of a region in different spectral ranges of interest. Accurate determination and interpretation of positional information may however be impaired if acquisition of the images is associated with a relative movement between the images. Known systems make use of a global positioning system (GPS) and/or an inertial measurement unit (IMU).
