1. An image acquisition device having a wide field of view, comprising:

  • at least one lens and image sensor configured to capture an original wide field of view (WFoV) image with a field of view of more than 90°

    ;

    a control module;

    an object detection engine comprising one or more cascades of regular object classifiers;

    a WFoV correction engine configured to correct distortion within the original image;

    wherein the WFoV correction engine processes raw image data of the original WFoV image including applying a rectilinear projection of center pixels of the original WFoV image and a cylindrical projection of outer pixels of the original WFoV image, and combining modified center and outer pixels to generate a distortion-corrected WFoV image; and

    wherein one or more objects located within the center or outer pixels, or both, of the distortion-corrected WFoV image are detectable by the object detection engine upon application of the one or more cascades of regular object classifiers.
