1. A camera-based driver-assistance system comprising:

  • a plurality of cameras each comprising an electro-optical component to capture images, wherein the cameras are located in different areas on a vehicle hosting the camera-based driver-assistance system;

    a feature point analyzer to determine, for the plurality of cameras, a first constraint set based on an estimated location of a plurality of feature points and an estimated orientation of the plurality of feature points in a ground plane proximate to the vehicle;

    a border analyzer to determine, for the plurality of cameras, a second constraint set based on one or more borders of the vehicle;

    a calibrator to conduct an automatic calibration of one or more of the plurality of cameras based on the first constraint set and the second constraint set; and

    a display to visually output a result of the automatic calibration.
