Abstract: Systems and methods for generating an omnidirectional mosaic image are presented in which a number of images are acquired about an axis of rotational. The images have a large field of view along the axis of rotation and a small field of view or image width in a second direction. The images can be image strips, formed from non-parallel rays directed onto an image sensor (1008), which are formed from a narrow width of parallel rays directed onto imaging sensor (1008). The images are combined to form a spherical mosaic. In the case of overlapping image strips, image combination can be performed by identifying common features in the overlapping regions and aligning consecutive image strips accordingly. A blending algorithm can then be used to improve image fidelity in the overlapping regions.
