Object Detection and Rendering for Wide Field of View (WFOV) Image Acquisition Systems

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 lens having a compressed rectilinear center portion 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 the lens also comprises cylindrical outer portions on either side of the compressed rectilinear portion 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;
• a 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.

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

• multiple cameras configured to capture an original wide field of view (WFoV) image with a field of view of more than 90°, the original wide field of view image comprising a combination of multiple images captured each with one of the multiple cameras, wherein the multiple cameras comprise a first camera having a first image sensor and a compressed rectilinear lens to capture a center region of a scene onto the first sensor such as to directly provide a rectilinear mapping of the center region, and a second camera having a second image sensor and a first cylindrical lens on a first side of the compressed rectilinear lens to capture a first outer region of the scene onto the second image sensor such as to directly provide a cylindrical mapping of the first outer region, and a third camera having a third image sensor and a second cylindrical lens on a second side of the compressed rectilinear lens to capture a second outer region of the scene onto the third image sensor such as to directly provide a cylindrical mapping of the second outer region;
• a control module;
• an object detection engine comprising one or more cascades of regular object classifiers;
• wherein one or more objects located within the original wide field of view image appearing on the multiple cameras of the original WFoV image are detectable by the object detection engine upon application of the one or more cascades of regular object classifiers.
