METHOD AND SYSTEM FOR GEOMETRIC REFERENCING OF MULTI-SPECTRAL DATA

摘要

The invention provides 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 comprising: a first and second 2D sensor element, the device obtaining subsequent multi-spectral images during said relative motion of the Rol with respect to the device 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 said first sequence of frames for which no synchronous frame from said second sequence of frames is available, derived from temporally similar frames from the second sequence of frames.
