Research Assistant, Ph.D. in Robotics, Georgia Institute of Technology
Wall Lab & BORG Lab, Institute for Robotics and Intelligent Machines

Previous Education:
M.Sc., Artificial Intelligence in Computing, Imperial College London
B.Sc., Electrical Engineering in Aeronauntics, Northwestern Polytechnical University

I am a Ph.D. student in Robotics at Georgia Tech, School of Interactive Computing, jointly advised by Prof. James Rehg, and Prof. Frank Dellaert. Before I started my Phd at Gatech, I finished my Master thesis under the supervision of Prof. Andrew Davison at Imperial College London.

Currently, I am a Phd intern working with Prof. Andreas Geiger at Autonomous Vision Group (AVG) Max Planck Institute.

My research interests cover computer vision researches as the perception for robot systems, particularly in the 3D scene understanding that can bridge perception to planning and control. My current focus is to explore efficient approaches for dense 3D motion (scene flow) from videos, which is the core of my thesis topic. My strenghts are in the following fields:

  • 3D Scene Flow, Optical Flow and Stereo.
  • Semantic Scene Understanding
  • Structure from Motion, Simultaneous Localization and Mapping

  • Office Address:
    College of Computing Building /
    Robotics & Intelligent Machines Center
    801 Atlantic Drive, Rm. 273B
    Atlanta, Georgia, U.S., 30308

    KinfuSeg: A Dynamic SLAM Approach Based on KinectFusion

    Master Thesis, Imperial College London
    Distinguished Thesis in Department of Computing (3 among 71), Top 5%
    Advisor: Prof. Andrew Davison

    Traditional SLAM methods works under the assumption that the evironment is totally static. When the scene is dynamic, both tracking and mapping will fail. In this project, this system is able to achieve:

    • Tracks the static scene, while segment out the dynamic object.
    • The first solution to real-time fuse dense 3D map for both static and dynamic scenes.

    Bachelor Quadrotor

    Quadrotor Design and its Navigation

    Bachelor Thesis, Northwestern Polytechnical University
    Advisor: Prof. Zhenbao Liu, Prof. Shuhui Bu, Prof. Xiaojun Tang

    The goal of this project is to build up a quad-rotor, with basic navigation and flight control system. The quad-rotor is able to achieve a stable flight with joystick control and hover autonomously.

    Learning Dense Scene Flow Fields from RGB-D Images
    Director: Jan Kautz
    Mentors: Kihwan Kim, Deqing Sun, Alejandro Troccoli
    I work in the Visual Computing and Machine Learning Research group, about the research problem learning scene flow from RGB-D images. Our learning based approach outperforms all existing approaches in terms of accuracy and robustness, and can generalize well to different challenging scenes.

    Qualcomm Research, Greater San Diego, May 2016 - Aug. 2016

    Sensor Fusion & Planning in Autonomous Vehicle
    Manager: Dr. Ali Agha
    I work in the Sensor Fusion and Motion Planning group. I proposed a factor graph representation for joint intention prediction and motion planning algorithm.
  • Submitted two first author patents about joint intention prediction and motion planning, which have been approved.
  • I also participated a 16-hour Qualcomm Hack-Mobile event. And our proposed distaster rescue on-site system won finalists (3/50 teams) in the hackthon event.
