Bidirectional Trajectory Computation for Odometer-Aided Visual-Inertial SLAM

نویسندگان

چکیده

Odometer-aided visual-inertial SLAM systems typically have a good performance for navigation of wheeled platforms, while they usually suffer from degenerate cases before the first turning. In this paper, firstly we perform an observability analysis w.r.t. extrinsic parameters turning, which is complement existing results analyses. Secondly, inspired by above analyses, propose bidirectional trajectory computation method, poses turning are refined in backward thread, and real-time adjusted accordingly. Experimental prove that our proposed method not only solves problem unobservability accelerometer bias but also more accurate trajectories comparison with state-of-the-art approaches.

Asynchronous Adaptive Conditioning for Visual-Inertial SLAM

This paper is concerned with real-time monocular visual inertial simultaneous localization and mapping (VI-SLAM). In particular a tightly coupled nonlinear-optimization based solution that can match the global optimal result in real time is proposed. The methodology is motivated by the requirement to produce a scale-correct visual map, in an optimization framework that is able to incorporate re...

Large Scale Dense Visual Inertial SLAM

In this paper we present a novel large scale SLAM system that combines dense stereo vision with inertial tracking. The system divides space into a grid and efficiently allocates GPU memory only when there is surface information within a grid cell. A rolling grid approach allows the system to work for large scale outdoor SLAM. A dense visual inertial dense tracking pipeline incrementally localiz...

Towards visual-inertial SLAM for mobile augmented reality

The basic idea of augmented reality is to augment the view of a user or camera with virtual objects. Real-time camera tracking is an enabling technology for augmented reality. Besides the high estimation precision that is needed to allow for pixel accurate augmentations, mobile augmented reality applications impose further requirements on the tracking method. One important aspect is robustness ...
