Single And Multi-Camera Calibration |
| 摘要 |
Camera calibration includes capturing a first image of an object by a first camera, determining spatial parameters between the first camera and the object using the first image, obtaining a first estimate for an optical center, iteratively calculating a best set of optical characteristics and test setup parameters based on the first estimate for the optical center until the difference in a most recent calculated set of optical characteristics and previously calculated set of optical characteristics satisfies a predetermined threshold, and calibrating the first camera based on the best set of optical characteristics. Multi-camera system calibration may include calibrating, based on a detected misalignment of features in multiple images, the multi-camera system using a context of the multi-camera system and one or more prior stored contexts. |

1. A method for camera calibration, comprising:
capturing a first image of an object by a first camera; determine spatial parameters between the first camera and the object using the first image; obtain a first estimate for an optical center; iteratively calculating a best set of optical characteristics and test setup parameters based on the first estimate for the optical center and the determined spatial parameters until the difference in a most recent calculated set of optical characteristics and previously calculated set of optical characteristics satisfies a predetermined threshold; and calibrating the first camera based on the best set of optical characteristics. |
