An N-Point Linear Solver for Line and Motion Estimation with Event Cameras

no code implementations1 Apr 2024 Ling Gao, Daniel Gehrig, Hang Su, Davide Scaramuzza, Laurent Kneip

To recover the full linear camera velocity we fuse observations from multiple lines with a novel velocity averaging scheme that relies on a geometrically-motivated residual, and thus solves the problem more efficiently than previous schemes which minimize an algebraic residual.

VECtor: A Versatile Event-Centric Benchmark for Multi-Sensor SLAM

no code implementations4 Jul 2022 Ling Gao, Yuxuan Liang, Jiaqi Yang, Shaoxun Wu, Chenyu Wang, Jiaben Chen, Laurent Kneip

Event cameras have recently gained in popularity as they hold strong potential to complement regular cameras in situations of high dynamics or challenging illumination.

Globally-Optimal Contrast Maximisation for Event Cameras

no code implementations10 Jun 2022 Xin Peng, Ling Gao, Yifu Wang, Laurent Kneip

The practical validity of our approach is demonstrated by a successful application to three different event camera motion estimation problems.

Globally-Optimal Event Camera Motion Estimation

no code implementations ECCV 2020 Xin Peng, Yifu Wang, Ling Gao, Laurent Kneip

The practical validity of our approach is supported by a highly successful application to AGV motion estimation with a downward facing event camera, a challenging scenario in which the sensor experiences fronto-parallel motion in front of noisy, fast moving textures.

FP-Loc: Lightweight and Drift-free Floor Plan-assisted LiDAR Localization

no code implementations1 Mar 2022 Ling Gao, Laurent Kneip

Our approach relies on robust ceiling and ground plane detection, which solves part of the pose and supports the segmentation of vertical structure elements such as walls and pillars.

Efficient Globally-Optimal Correspondence-Less Visual Odometry for Planar Ground Vehicles

no code implementations1 Mar 2022 Ling Gao, Junyan Su, Jiadi Cui, Xiangchen Zeng, Xin Peng, Laurent Kneip

We encountered this difficulty by introducing the first globally-optimal, correspondence-less solution to plane-based Ackermann motion estimation.

Exploring the Impact of Negative Samples of Contrastive Learning: A Case Study of Sentence Embedding

1 code implementation Findings (ACL) 2022 Rui Cao, Yihao Wang, Yuxin Liang, Ling Gao, Jie Zheng, Jie Ren, Zheng Wang

We define a maximum traceable distance metric, through which we learn to what extent the text contrastive learning benefits from the historical information of negative samples.

ESOD:Edge-based Task Scheduling for Object Detection

no code implementations20 Oct 2021 Yihao Wang, Ling Gao, Jie Ren, Rui Cao, Hai Wang, Jie Zheng, Quanli Gao

In detail, we train a DNN model (termed as pre-model) to predict which object detection model to use for the coming task and offloads to which edge servers by physical characteristics of the image task (e. g., brightness, saturation).

Learning to Remove: Towards Isotropic Pre-trained BERT Embedding

1 code implementation12 Apr 2021 Yuxin Liang, Rui Cao, Jie Zheng, Jie Ren, Ling Gao

We train the weights on word similarity tasks and show that processed embedding is more isotropic.

To Compress, or Not to Compress: Characterizing Deep Learning Model Compression for Embedded Inference

no code implementations21 Oct 2018 Qing Qin, Jie Ren, Jialong Yu, Ling Gao, Hai Wang, Jie Zheng, Yansong Feng, Jianbin Fang, Zheng Wang

We experimentally show that how two mainstream compression techniques, data quantization and pruning, perform on these network architectures and the implications of compression techniques to the model storage size, inference time, energy consumption and performance metrics.
