Abstract:
1. An image acquisition device having a wide field of view, comprising: a lens assembly and image sensor configured to capture an original wide field of view (WFoV) image with a field of view of more than 90°, wherein the lens assembly comprises a compressed rectilinear lens to capture a center region of a scene onto a middle portion of the image sensor such as to directly provide a rectilinear mapping of the center region and a cylindrical lens on one or both sides of the compressed rectilinear lens to capture outer regions of the scene onto outer portions of the image sensor such as to directly provide a cylindrical mapping of the outer regions; a control module; an object detection engine comprising one or more cascades of regular object classifiers; wherein one or more objects located within the center or outer pixels, or both, of the original WFoV image are detectable by the object detection engine upon application of the one or more cascades of regular object classifiers.
