Figure Lengend Snippet: Error distributions of pinhole radial–tangential model parameters and the root mean square (RMS) reprojection errors, by five geometric camera calibration tools, BabelCalib, Camodocal, Kalibr/TartanCalib, the MATLAB calibrator, and the ROS/OpenCV calibrator, on the simulated data for S04525, E1M3518, and BM4218 lenses, each with nine sequences. Note that BabelCalib used a pinhole radial model, resulting in zero values in p 1 and p 2 , which are shown relative to the true values.

doi: 10.3390/s24206595

Figure Lengend Snippet: Error distributions of KB-8 parameters and the root mean square (RMS) reprojection errors, using five geometric camera calibration tools, BabelCalib, Basalt, Camodocal, Kalibr, and the OpenCV-based ROS calibrator, on the simulated data for BM4218, BM4018, BT2120, and MTV185 lenses, each with nine sequences. The results of the ROS calibrator for the BM4218, BT4018, and MTV185 lenses, and the MATLAB calibrator for the MTV185 lens, were excluded due to persistent failures.

Figure Lengend Snippet: Error distributions of Mei parameters and the root mean square (RMS) reprojection errors, by geometric camera calibration tools, BabelCalib, Basalt, Camodocal, Kalibr, and the OpenCV-based ROS camera calibrator, on the simulated data for BM4018, BT2120, and MTV185 lenses, each with nine sequences. BabalCalib and Basalt used the extended unified camera model (EUCM), while the others used the Mei model. Note that the β of the EUCM is shown together with k 1 of the Mei model relative to k 1 ’s true value. A parameter unavailable to the EUCM, e.g., k 2 , is zero by default, and shown relative to the parameter’s true value. Basalt failed all MTV185 sequences.

Figure Lengend Snippet: Pinhole radial–tangential model parameters and the root mean square (RMS) reprojection errors, by geometric camera calibration tools, BabelCalib, Camodocal, Kalibr, the MATLAB calibrator, and the ROS/OpenCV camera calibrator, on the real datasets captured with S04525, E1M3518, and BM4218 lenses, each with nine sequences. Note that BabelCalib adopted a pinhole radial model. The ROS calibrator failed four out of nine times for the BM4218 dataset.

Basalt failed 7 out of 9 times for both the BM4218 and MTV185 datasets, leading to its small variances.

Figure Lengend Snippet: Mei parameters and the root mean square (RMS) reprojection errors by geometric camera calibration tools, BabelCalib with the extended unified camera model (EUCM), Basalt with the EUCM, Camodocal, Kalibr/TartanCalib, and the ROS/OpenCV camera calibrator, on the real data captured with BM4018, BT2120, and MTV185 lenses, each with nine sequences. Note that the EUCM model parameter β is shown together with the Mei parameter k 1 . The unavailable parameters, e.g., k 2 to the EUCM model, are zero by default. Basalt failed 8 out of the 9 MTV185 sequences.
