Abstract
A method for calibrating a plurality of cameras. The method includes: for each camera, detecting a projection of a proxy object included in an image captured by the camera; for each camera, detecting surface features associated with the proxy object included in the image captured by the camera; for each combination of two different cameras, determining a correspondence set that maps the detected surface features associated with the proxy object included in the image captured by one camera to the detected surface features associated with the proxy object included in the image captured by the other camera; and generating correspondences between features based on relationships between the different correspondence sets, wherein the correspondences between features can be processed by a camera calibration toolbox to generate camera calibration parameters for each camera in the plurality of cameras.
