First Claim
Patent Images
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 a 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.

Abstract
Methods, apparatuses, and systems may provide for using the motion of a vehicle to estimate the orientation of a camera system of a vehicle relative to the vehicle. Image data may be received from a plurality of cameras positioned on the vehicle, and a first constraint set may be determined for the plurality of cameras based on a plurality of feature points in a ground plane proximate to the vehicle. A second constraint set may be determined based on one or more borders of the vehicle. One or more of the cameras may be automatically calibrated based on the first constraint set and the second constraint set.
