cam_mat_to_cam_par( : : CameraMatrix, Kappa, ImageWidth, ImageHeight : CameraParam)

描述

cam_mat_to_cam_parcam_mat_to_cam_parCamMatToCamParCamMatToCamParCamMatToCamParcam_mat_to_cam_par computes internal camera parameters from the camera matrix CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrixcamera_matrix, the radial distortion coefficient KappaKappaKappaKappakappakappa, the image width ImageWidthImageWidthImageWidthImageWidthimageWidthimage_width, and the image height ImageHeightImageHeightImageHeightImageHeightimageHeightimage_height. The camera parameters are returned in CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param. The parameters CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrixcamera_matrix and KappaKappaKappaKappakappakappa can be determined with stationary_camera_self_calibrationstationary_camera_self_calibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationstationary_camera_self_calibration。cam_mat_to_cam_parcam_mat_to_cam_parCamMatToCamParCamMatToCamParCamMatToCamParcam_mat_to_cam_par converts this representation of the internal camera parameters into the representation used by camera_calibrationcamera_calibrationCameraCalibrationCameraCalibrationCameraCalibrationcamera_calibration。The conversion can only be performed if the skew of the image axes is set to 0 in stationary_camera_self_calibrationstationary_camera_self_calibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationstationary_camera_self_calibration, i.e., if the parameter 'skew'"skew""skew""skew""skew""skew" is not being determined.
