About Me

I am a Postdoctor in the AirLab of Robotics Institute, Carnegie Mellon University (CMU) , working with Associate Research Professor Sebastian Scherer. Before that I was a PhD student of SPL under the supervision of Professor Wen Yang at Wuhan Univeristy. Now my research is on Computer Vision and Robotics. Particularly I am interested in 2D/3D visual correspondence for registration, calibration and camera localization.

Selected Projects

ICRA2018 DJI RoboMaster AI Challenge (DOTA-AI), 2018
TensorFlow ROS Python C++ OpenCV SqueezeDet

In this project, we designed a multi-functional AI robot system, which can be used to evaluate the localization and navigation, object detection and tracking methods. We developed a robot localization algorithm based on mult-sensor fusion. It won 6th place in the DJI RoboMaster AI Challenge.

Demo

The Intelligent Unmanned Aircraft System for Wilderness Search and Rescue (WiSAR), 2017
C++ ROS YOLO SSD Faster R-CNN Qt

In this project, we collected about 20,000 images to build a UAV perspective person dataset (UAV-PP) and adapted detection algorithms YOLOv2, SSD and Faster R-CNN for person detection and chose the SSD as the detection algorithm because it’s balance on accuracy and speed, the detection accuracy achieved 88.92%.

Demo Poster

ICRA2017 DJI RoboMaster Mobile Manipulation Challenge, 2017
C++ ROS OpenCV

In this project, we designed a robot to carry blocks from the starting point to the working area. It contain four main modules, i.e. mechanical module, global navigation module, local navigation module and the designed controlling logic. It won 6th place in the DJI RoboMaster Mobile Manipulation Challenge.

Demo

2016 DJI Developer Challenge
C++ ROS OpenCV

We developed a UAV system based on DJI M100 and a ground station to search objects (AprilTags) in wild with DJI Onboard and Mobile SDK. The robot can autonomous take-off and land on a moving platform. By using stereo vision and ROS navigation package, we also made it possible for autonomous search targets in the wild. It won 3th place in the 2016 DJI Developer Challenge.
