Abstract
A sensing device for obtaining geometric referenced multi-spectral image data of a RoI in relative movement with respect to the device, the sensing device having: a first and second 2D sensor element, the device obtaining subsequent multi-spectral images during the relative motion of the Rol thus providing distinct spectral information for parts of a Rol using the first element; and providing, using the second element, an image of the Rol for generating geometric referencing information to be coupled to the distinct spectral information; each element capturing a sequence of frames at a respective frame rate. The first frame rate is higher than the second frame rate. The device generates intermediate geometric referencing information to be coupled to frames of the first sequence of frames for which no synchronous frame from the second sequence of frames is available, derived from temporally similar frames from the second sequence of frames.
