DIME-Net: Neural Network-Based Dynamic Intrinsic Parameter Rectification for Cameras with Optical Image Stabilization System

no code implementations20 Mar 2023 Shu-Hao Yeh, Shuangyu Xie, Di Wang, Wei Yan, Dezhen Song

Here we propose a novel neural network-based approach that estimates $\mathrm{K}$ matrix in real-time so that pose estimation or scene reconstruction can be run at camera native resolution for the highest accuracy on mobile devices.

STA-VPR: Spatio-temporal Alignment for Visual Place Recognition

1 code implementation25 Mar 2021 Feng Lu, Baifan Chen, Xiang-Dong Zhou, Dezhen Song

Here we split the holistic mid-layer features into local features, and propose an adaptive dynamic time warping (DTW) algorithm to align local features from the spatial domain while measuring the distance between two images.

Graph-based Proprioceptive Localization Using a Discrete Heading-Length Feature Sequence Matching Approach

no code implementations27 May 2020 Hsin-Min Cheng, Dezhen Song

As a robot/vehicle travels, we extract a sequence of heading-length values for straight segments from the trajectory and match the sequence with a pre-processed heading-length graph (HLG) abstracted from the prior known map to localize the robot under a graph-matching approach.

Semi-Semantic Line-Cluster Assisted Monocular SLAM for Indoor Environments

no code implementations5 Nov 2018 Ting Sun, Dezhen Song, Dit-yan Yeung, Ming Liu

In the back end, we optimize the map imposing the constraint that the line segments of the same cluster should be the same.

Robust RGB-D Odometry Using Point and Line Features

no code implementations ICCV 2015 Yan Lu, Dezhen Song

To meet the challenges, we fuse point and line features to form a robust odometry algorithm.
