Work

  • 2022.12 - Present
    ML Software Development Working Student
    Infineon Technologies AG
    Setup radar DSP preprocessing stack and the entire ML infrastructure from data collection, annotation and loader. Design an end‑to‑end transformer‑based neural network for radar material classification aiming to lawn mower and vacuum cleaner robot. Setup the solution for deploying/compiling our transformer‑based model onto bare‑metal device (PSoC6) using TFLITE/TVM framwork.

    VXP: Voxel-Cross-Pixel Large-scale Image-LiDAR Place Recognition
    arXiv
    We propose a novel Voxel-Cross-Pixel (VXP) approach, which establishes voxel and pixel correspondences in a self-supervised manner and brings them into a shared feature space. We achieve state-of-the-art performance in cross-modal retrieval on the Oxford RobotCar, ViViD++ datasets and KITTI benchmark, while maintaining high uni-modal global localization accuracy.

Projects

  • 2023.02 - 2023.03
    Visual-SLAM: Loop Closure and Relocalization
    Extend the Visual Odometry framework into Visual SLAM system, and achieve an outstanding performance on EuRoC Vicon Room 1 and EuRoC Machine Hall dataset.

    • Bundle Adjustment
  • 2022.12 - 2023.01
    Visual-Inertial Tracking using Preintegrated Factors
    Extend the Visual Odometry framework into Visual‑Inertial Odometry. Instead of performing local bundle adjustment by minimizing the reprojection errors in the sliding window of keyframes, we compute preintegrated factor from the IMU measurement to serve as a constraint in the loss function to make the optimization more robust.
