GEOMETRIC REFERENCING OF MULTI-SPECTRAL DATA

摘要

A sensing device is described for obtaining geometric referenced multi-spectral image data of a region of interest in relative movement with respect to the sensing device. The sensing device comprises a first two dimensional sensor element (112) and a spectral filter (114). The sensing device (100) is adapted for obtaining subsequent multi-spectral images during said relative motion of the region of interest with respect to the sensing device thus providing spectrally distinct information for different parts of a region of interest using different parts of the first sensor. The sensing device (100) also comprises a second two dimensional sensor element (122) and is adapted for providing, using the second sensor element (122), an image of the region of interest for generating geometric referencing information to be coupled to the distinct spectral information. The first sensor element (112) and second sensor element (122) of the sensing device are integrated on the same substrate.
