PhD researcher at the University of Maine

Md Mehedi Hasan

PhD student in Electrical and Computer Engineering at the University of Maine. I build systems that help machines see, map, and understand the 3D world, from multi-robot mapping and augmented reality to animatable 3D humans.

Research

What I'm working on now. Filter by area.

Robotics

Multi-robot SLAM on edge devices

Two Jetson Orin robots with depth cameras map a space together. A shared server merges both maps into one and tracks where each robot is relative to the other.

Details
  • Split pipeline: tracking on each robot, map building on the server
  • Map merging with duplicate map point removal
  • Live inter-robot distance and color-coded maps per robot
Neural rendering

Animatable 3D humans from video

Building 3D human avatars that can be posed and re-rendered, using SMPL body models and NeRF-style rendering.

NeuMan4DHumansSMPLPyTorch3D
Details
  • Replacing NeuMan's body estimator with 4DHumans (HMR 2.0)
  • Evaluated with PSNR, SSIM, and LPIPS on six benchmark sequences
Embedded systems

Solar-powered LoRa mesh sensing

A low-power sensor network: small STM32 nodes report over LoRa to a Jetson base station that uploads data over LTE.

Outreach

Live object detection for high schoolers

A hands-on demo on a Jetson Orin where students point a camera at anything, type what to look for, and watch the model find it.
