Line based slam
Nettet16. jul. 2024 · Although it is feasible to construct a complete SLAM system based on line features alone , this yields no significant improvement in performance and often performs worse than point-based SLAM. Recent works [ 57 , 58 , 59 ] have demonstrated that leveraging both point and line features can lead to a robust SLAM system based on … Nettet5. jul. 2024 · Traditional visual simultaneous localization and mapping (SLAM) systems rely on point features to estimate camera trajectories. However, feature-based systems are usually not robust in complex environments such as weak textures or obvious brightness changes. To solve this problem, we used more environmental structure …

Nettet18. nov. 2024 · This paper presents a new line based 6-DOF monocular algorithm that uses the iSAM2, a point-based Graph SLAM approach. We extend iSAM2 to minimize the reproject NettetB. Line-based SLAM with Manhattan or Atlanta World As-sumption In [22], [23], rotation matrix was estimated using the Manhattan world assumption. Based on this, decoupled methods have been proposed to estimate the translation after calculating the rotation through the vanishing points [24]–[26].In addition, some approaches applied line

Nettet27. des. 2024 · As a result, problems like degeneracy that occur during the 3D line mapping process cannot be solved. To tackle the problem, this paper presents a UV-SLAM, which is an unconstrained line-based ...
Nettet7. mar. 2024 · Visual odometry, which aims to estimate relative camera motion between sequential video frames, has been widely used in the fields of augmented reality, virtual reality, and autonomous driving. However, it is still quite challenging for state-of-the-art approaches to handle low-texture scenes. In this paper, we propose a robust and … Nettet29. jun. 2024 · Event-based cameras generate asynchronous streams of events, triggered proportionally to the logarithmic change of brightness in the scene.
