DK-SLAM: Monocular Visual SLAM with Deep Keypoints Adaptive Learning, Tracking and Loop-Closing

no code implementations17 Jan 2024 Hao Qu, Lilian Zhang, Jun Mao, Junbo Tie, Xiaofeng He, Xiaoping Hu, Yifei Shi, Changhao Chen

Unreliable feature extraction and matching in handcrafted features undermine the performance of visual SLAM in complex real-world scenarios.

SelfOdom: Self-supervised Egomotion and Depth Learning via Bi-directional Coarse-to-Fine Scale Recovery

no code implementations16 Nov 2022 Hao Qu, Lilian Zhang, Xiaoping Hu, Xiaofeng He, Xianfei Pan, Changhao Chen

To address this, we propose SelfOdom, a self-supervised dual-network framework that can robustly and consistently learn and generate pose and depth estimates in global scale from monocular images.

A Pose-only Solution to Visual Reconstruction and Navigation

1 code implementation2 Mar 2021 Qi Cai, Lilian Zhang, Yuanxin Wu, Wenxian Yu, Dewen Hu

Visual navigation and three-dimensional (3D) scene reconstruction are essential for robotics to interact with the surrounding environment.

Equivalent Constraints for Two-View Geometry: Pose Solution/Pure Rotation Identification and 3D Reconstruction

no code implementations13 Oct 2018 Qi Cai, Yuanxin Wu, Lilian Zhang, Peike Zhang

The PPO constraints are simplified and formulated in the form of inequalities to directly identify the right pose solution with no need of 3D reconstruction and the 3D reconstruction can be analytically achieved from the identified right pose.
