Huaiyang HUANG
I am a Ph.D. candidate in the Department of Computer Science and Engineering, of RAM-Lab at Robotics Institute, the Hong Kong
University of Science and Technology,
supervised by Prof. Ming LIU. I received my B.E. degree in Mechatronics
from Zhejiang University, where I was a member of robot
soccer team ZJUDancer.
In the past years, I mainly work on localization,
mapping and 3D
reconstruction with various sensor configurations. In particular, I am interested in cutting-edge
technologies for geometry-related problems in autonomous navigation and 3D vision.
Reasearch Projects
Robust Localization Aided by Dense Scene Geometry
Developing a system that localizes and tracks a low-cost sensor suite (e.g., monocular-inertial sensor) within a accurate dense map building by laser scanners. To alleviate challenges (illumination change, view-point variances, etc) in feature-based visual localization pipeline, this project introduces dense scene geometry in the process of visual localization. Various dense map representation are investigated for localization, including Signed Distance Field (SDF), Surfel Map and Gaussian Mixture Model (GMM). In addition to dense structure, other modalities like inertial measurements can also be fused into the localization process. For details please see the links below.

Localization and Mapping with Diverse Sensor Configuration
Developing localization and mapping systems with diverse sensor configurations, including cameras, LiDAR, IMU, wheeled odometer etc. Firstly, we develop a system that efficiently builds a dense map with multiple point cloud scans. Instead of using traditional scan-to-model or pose synchronization-based pipeline, the system introduces a novel formulation of point cloud Bundle Adjustment (BA), which improves the local consistency of map while maintaining better efficiency. The system is then extended to a LiDAR-based SLAM system with a visibility graph between map component and frames and a deformation-based loop correction module. Global map consistency cloud be well maintained in a campus-level dataset by the proposed system. The system achieves SOTA performance on public dataset and ranks 8-th on KITTI Odometry benchmark. In addition, we introduce learnt features into visual SLAM systems. We propose a two-stage direct tracking method by maximizing the predicted repeatability of landmarks. The system achieves sota performance in public datasets KITTI Odometry and EuRoC. We also extend the system into a localization system and performed several tests in various real-world scenarios, including public road, campus and harbor. For details please see links below.
