Low-power embedded system for real-time correction of fish-eye automotive cameras

The design and the implementation of a flexible and cost-effective embedded system for real-time correction of fish-eye automotive cameras is presented. Nowadays many car manufacturers already introduced on-board video systems, equipped with fish-eye lens, to provide the driver a better view of the so-called blind zones. A fish-eye lens achieves a larger field of view (FOV) but, on the other hand, causes distortion, both radial and tangential, of the images projected on the image sensor. Since radial distortion is noticeable and dangerous, a real-time system for its correction is presented, whose low-power, low-cost and flexibility features are suitable for automotive applications.
