About Me

I am Pengfei Li, a robotics master student in Laboratory for Computational Sensing and Robotics (LCSR), Johns Hopkins University.
I graduated from Zhejiang University with honors, majoring in Electrical Engineering. I was also a member of Advanced Class of Engineering Education(ACEE) in Chu Kochen Honor College.
In summer 2017, I took part in the International Summer Research Program in UCSD from July 6th to September 6th. I spent a very happy time working under the guidance of Prof. Atanasov as a research intern.
In summer 2016, I attended SENG Summer Camp For Elite Students in HKUST and visited some of the labs in SENG.
I am really interested in Robotics Design, Control and Sensing. I did some projects about wheeled robots, bipedal robots and exoskeleton based on artificial muscle. I strongly believe that 'Iron man' will come true in the near future. Currently, I am trying to employ some deep learning methods to extract semantic information from image squence.

Research


And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
-- Steve Jobs


State Key Lab of CAD & CG, Zhejiang University

Research Intern, Research on the Semantic Simultaneous Localization and Mapping (SLAM)
Advisor: Dr. Xiaowei Zhou

10/2017 - Present
  • Implemented Visual-Inertial Odometry (VIO) based on filter methods in MATLAB, compared the
    results with ground truth with KITTI dataset;
  • Detected landmarks (vechiles) based on 'Single Shot MultiBox Detector'; detected semantic
    keypoints on these landmarks based on 'staked hourglass'
  • Estimated the 6-DoF pose of landmarks in KITTI dataset, by optimizing the loss function with
    projective gradient descent; improved accuracy and convergence speed by applying the
    Gauss-Newton method on Lie Algebra (a real vector space)
  • Programed in ROS using C++ and Python; Visualized the results in Rviz
  • Trying to fuse the measurement in the image sequence, aiming to enhance the trajectory
    and map accuracy with the reconstructed 3D map of landmarks.

Existential Robotics Laboratory, University of California, San Diego

Research Intern, Research on the Simultaneous Localization and Mapping (SLAM)
Advisor: Prof. Nikolay A. Atanasov

07/2017-09/2017
  • Studied the different methods for robotics localization and mapping, including
    encoder model, occupancy grid mapping, Multi-State Constraint Kalman Filter (MSCKF),
    Kalman filter, recursive Bayesian filter, and PHD filter; analyzed the advantages and
    disadvantages of the aformentioned methods
  • Compared classical SLAM with Semantic SLAM; implemented Kalman filer and the
    Gaussian Mixture PHD filter with Matlab, as well as DPM and PHD filter in the ROS to
    construct a map of chairs in the simulation environment.
