Abstract
Homography-based imaging apparatus and method are provided. The apparatus may include a processor (44) coupled to process respective sequences of sky images respectively acquired by physical image acquisition devices 181 and 182 at respective spaced apart locations (e.g., P1, P2). The processor may include an image alignment module (32) configured to spatially relate respective views of at least one object (e.g., clouds, aerial vehicles) visible in the respective sequences of the sky images based on homography (42) of at least one astronomical image acquired at each spaced apart location. The astronomical image may include a number of spatial references corresponding to respective astronomical body positions located practically at infinity relative to a respective distance between the spaced apart locations. Further views (synthetic views) may be generated at selectable new locations (e.g., P3, P4, P5, P6), without actually having any physical image acquisition devices at such selectable locations.
