“…According to the earlier work from Kumar et al [7] and Edwards et al [8], the geometric error follows a two dimensional Gaussian distribution in the constant lighting environment, and the two dimensions are isotropically distributed as long as the camera is stable, so that the covariance of the extracted feature location error can be represented as…”

“…However, the statistics of residuals is obviously not a proper error model, since the estimated states used for calculating the reprojection error can already be biased. Kumar and Osechas have shown in [7], and Edwards et al have shown in [8] that for designed patterns, the feature location error follows a Gaussian distribution in nominal situations. Nevertheless, the results are still qualitative, since the variance of the distribution is still an ad-hoc value obtained from experiments for particular scenarios.…”

Munich. His research interests include visual navigation, multi-sensor fusion, robotic swarm navigation, and he is focusing on the integrity of the techniques. Christian Steinmetz obtained a Bachelor of Science degree in Electrical Engineering and Information Technology at the Technical University of Munich. He is currently studying the consecutive Master's program there. For his Master's thesis, he joined the Department of Navigation at the Institute of Communications and Navigation, German Aerospace Center (DLR). Boubeker Belabbas obtained a MSc. Degree in Mechanical Engineering from ENSEM in Nancy (France) and a specialized MSc. Degree in Aerospace Mechanics from SUPAERO in Toulouse (France). He joined DLR in 2001 and developed the navigation integrity activities. He now leads the GNSS integrity team within the Department of Navigation at the Institute of Communications and Navigation. His field of competence includes GNSS with augmentations (SBAS, GBAS), Advanced Receiver Autonomous Integrity Monitoring, GNSS/INS Hybridization with integrity, and Alternative Positioning Navigation and Timing.
