Abstract

Apparatus (60) and methods for producing and displaying panoramic images. The apparatus includes a plurality of video sensor heads (92), each sensor head generating video signals corresponding to a partial image having a respective field of view (100), such that at least some of the fields of view include regions of substantial overlap (124) with respective neighboring fields of view, and a union of the fields of view substantially covers a scene having an angular extent beyond the field of view of any one of the sensor heads. A processor (40) receives and combines the partial images from the sensor heads to produce a panoramic image (231) of the scene. The panoramic image is displayed by defining an annular strip (230) and a point of view outside a volume bounded by the strip, and mapping the panoramic image onto the annular strip. An image of the strip, as seen from the point of view, is rendered to a video display (50).
