Abstract: The calibration system of the farming machine receives images from the camera array. The images comprise visual information representing a view of a portion of an area surrounding the farming machine. To calibrate the camera array, the system determines a relative pose between pairs of cameras by extracting relative position and orientation characteristics from visual information in images captured by the camera pairs. The calibration system determines a calibration error in part by propagating the relative poses between camera pairs. The calibration system may perform automated self-calibration by adjusting one or more of the cameras in the camera array, or may transmit remedial instructions to an operator to adjust the one or more cameras in the camera array.

Abstract: The calibration system of the farming machine receives images from each camera of the camera array. The images comprise visual information representing a view of a portion of an area surrounding the farming machine. To calibrate a pair of cameras including a first camera and second camera, the calibration system determines a relative pose between the pair of cameras by extracting relative position and orientation characteristics from visual information in both an image received from the first camera and an image received from the second camera. The calibration system identifies a calibration error for the pair of cameras based on a comparison of the relative pose with an expected pose between the first pair of cameras. The calibration system transmits a notification to an operator of the farming machine that describes the calibration error and instructions for remedying the calibration error.
