Localization and 3D Reconstruction
Preliminary work on mapping in Visually-degraded EnvironmentsThese are preliminary results on exploration and mapping inside a tunnel with approximate dimensions of WIDTHxHEIGHTxLENGTH = 3x4x30m. The robot navigated along half of it (approximately) and our team evaluated the capability of localization and mapping using NIR camera/IMU, as well as Laser Time-of-Flight sensors.

LiDAR-Visual-Inertial Fused Mapping for Cars - Preliminary Result - UNR GarageThis is a preliminary result with a system consisting of a Velodyne PuckLITE, a Stereo camera and an Inertial Measurement Unit. The data are processed through 2 pipelines, namely LiDAR odometry and visual-inertial odometry. The final result is fused through an EKF and direct IMU feeds. This map presents the depth data from the combination of the LiDAR and the stereo camera system. For the camera system a pruning distance of 2m is set.
