WebMar 14, 2024 · Robust positioning is a central issue in robots. Due to the complex indoor environment, VSLAM is susceptible to light and some scenes contain few features. The robot cannot obtain an accurate position. To solve these problems, this work first proposes DAT-SLAM, a method for extracting feature points based on a dynamic adaptive … WebAug 28, 2024 · An improved feature-based SLAM for dense mapping is proposed in this paper to easy follow-up works of robots. Features are extracted by original ORB-SLAM for pose estimation. Filter is used to get gradient graph for each image and points whose gradient are higher than threshold is added as feature points, then a voxel filter is …

WebJan 13, 2016 · SLAM is a real-time version of Structure from Motion (SfM). Visual SLAM or vision-based SLAM is a camera-only variant of SLAM which forgoes expensive laser sensors and inertial measurement units (IMUs). Monocular SLAM uses a single camera while non-monocular SLAM typically uses a pre-calibrated fixed-baseline stereo camera rig.

The SLAM algorithm then made two significant improvements to the RBPF algorithm: improved proposal distribution and adaptive …
WebSep 30, 2024 · The Simultaneous Localization and Mapping (SLAM) problem addresses the possibility of a robot to localize itself in an unknown environment and simultaneously build a consistent map of this environment. Recently, cameras have been successfully used to get the environment’s features to perform SLAM, which is referred to as visual SLAM … WebApr 9, 2024 · Point-SLAM: Dense Neural Point Cloud-based SLAM. We propose a dense neural simultaneous localization and mapping (SLAM) approach for monocular RGBD input which anchors the features of a neural scene representation in a point cloud that is iteratively generated in an input-dependent data-driven manner. We demonstrate that …
