More Information
Summary:The invention pertains to a method for geometric referencing of multi-spectral data in a sequence of images, the images containing distinct regions representing imaged radiation in respective distinct wavelengths, the method comprising: selecting a subset from the sequence of images, said subset containing a plurality of images, each image of which represents a field of view that overlaps with a field of view of at least one other image in the same subset; generating a 3D model by performing photogrammetric 3D reconstruction on the images in the subset; estimating a displacement and a yaw between pairs of successive images of said sequence of images; and using said 3D model and said estimated displacement and yaw to calculate photogrammetric parameters for images of said sequence of images that are not in said selected subset. The invention also pertains to a corresponding system and a corresponding computer program product.
