Evaluation and Software Implementations in Out-/Indoor Navigation based on Visual Odometry for Mono Cameras
Status: Abgeschlossen, April 2016
Bearbeitung: M.Sc. Fickrie Muhammad
The navigation solution for indoor environments especially for GPS-denied area is evaluated in this thesis, based on a monocular web camera without artificial markers or IMU (inertial measurement unit) sensors. The evaluation mainly focus on the feature tracking robustness of PTAM and SVO algorithms.
The evaluation approach considers the drift of SVO and PTAM against ground truth, which the least squares estimation is used to estimate scale, rotation and translation between SVO, PTAM and ground truth frames. The projection error of camera is calculated with camera calibration software from ROS and PTAM package.
