Abstract
Method and apparatus for calibrating multiple cameras. A first mirror and a second mirror are arranged opposite each other. An object is disposed between the first mirror and the second mirror. Calibration of the multiple cameras is performed using a figure of the object formed on the second mirror via reflection from the first mirror and the second mirror.
Claims20
An apparatus for calibrating multiple cameras, comprising:
- a first mirror;
- a second mirror arranged opposite the first mirror;
- and
- an object disposed between the first mirror and the second mirror,
- wherein multiple cameras are calibrated using a figure of the object formed on the second mirror via reflection from the first mirror and the second mirror.
A method for calibrating multiple cameras, comprising:
- setting up an environment for calibration of multiple cameras;
- capturing an image of a second mirror using the multiple cameras, thus generating the image;
- acquiring information for calibration of the multiple cameras using the image;
- and
- performing calibration of the multiple cameras using the acquired information,
- wherein a first mirror and the second mirror are arranged opposite each other, and
- wherein the image indicates a figure of an object formed on the second mirror via reflection from the first mirror and the second mirror.
A method for calibrating multiple cameras, the method being performed by multiple cameras disposed between a first mirror and a second mirror, the method comprising:
