Eckenhoff et al. In this paper, we propose VISO, a robust underwater SLAM system that fuses a stereo camera, an inertial measurement unit (IMU), and a 3D sonar to achieve accurate 6-DoF localisation and enable efficient dense 3D reconstruction with A Visual-Inertial Simultaneous Localization and Mapping (VI-SLAM) system with Android sensor data collection and PC-based SLAM processing. One option for increasing the estimation accuracy and robustness of VI-SLAM methods is to leverage multiple cameras mounted on the robot. Traditional visual simultaneous localization and mapping (SLAM) methods primarily rely on passive vision, such as monocular cameras, which often exhibit reduced accuracy in localization and struggle to create dense maps in low-light underwater conditions. The estimation of the initial state (camera poses, IMU states and landmark positions) from the first data readings lacks the accuracy and robustness of other parts of the pipeline, and most algorithms have high failure rates and/or 4 days ago · 0 求助 应助 收藏 GIVL-SLAM: A Robust and High-Precision SLAM System by Tightly Coupled GNSS RTK, Inertial, Vision, and LiDAR IEEE-ASME TRANSACTIONS ON MECHATRONICS (IF:7. 3) 2024-01-01 0 A visual-inertial state estimator system based on point-line features and structure constraints (PLS-VINS), which combines both of points and line segments to enhance the performance of feature extraction in a wider variety of scenarios and optimizes the system states by jointly minimizing the pre-integration constraints of inertial measurement .
