Basic surround-view Parking systems

Parking Surround-view systems generally use four to six wide-angle-view cameras mounted on the front, rear and sides of a vehicle. The fish-eye lenses used on these cameras produce a distorted bowl-shaped view that geometric alignment algorithms correct. These corrected images then need balancing and color correction for consistency and final stitching into a single 360-degree view around the car.

An animated model of the car is rendered at the center of the stitched image to give the driver a bird’s eye view of her environment. It is also possible to add other overlays to the image that show the car’s position relative to objects that the cameras see.

A system-on-chip (SoC) for this application requires capacity for multiple camera inputs, an image signal processor and hardware acceleration for image adjustment and tuning, a graphics processing unit for creating the car model, and image overlays and processing cores for algorithmic analysis of the images.
