SURROUND-VIEW CAMERA SYSTEM (VPM) AND VEHICLE DYNAMIC |
摘要 |
A system and method for correcting the calibration of a plurality of cameras on a mobile platform such as in a surround-view camera system on a vehicle based on changes in vehicle dynamics. The method includes reading measurement values from one or more sensors on the vehicle that identify a change in vehicle dynamics and defining the plurality of cameras and a vehicle body as a single reference coordinate system. The method also includes identifying the measured values as a rotation matrix and a translation vector in the coordinate system, and integrating the rotation matrix and the translation vector into a relationship between a vehicle coordinate system and a camera coordinate system to provide the calibration correction of the cameras. |

1. A method for correcting a calibration of a plurality of cameras in a surround-view camera system on a vehicle, said method comprising:
reading measurement values from one or more sensors on the vehicle that identify a change in vehicle dynamics; defining the plurality of cameras and a vehicle body as a single reference coordinate system; identifying the measured values as a rotation matrix and a translation vector in the reference coordinate system; and integrating the rotation matrix and the translation vector into a relationship between a vehicle coordinate system and a camera coordinate system to provide the correction of the camera calibration. |
