MoreFusion is an object-level reconstruction system that builds a map with known-shaped objects, exploiting volumetric reconstruction of detected objects in a real-time, incremental scene reconstruction senario. The key components are:
- Occupancy-based volumetric reconstruction of detected objects for model alignment in the later stage;
- Volumetric pose prediction that exploits volumetric reconstruction and CNN feature extraction from the image observation;
- Joint pose refinement of objects based on geometric consistency among objects and impenetrable space.
There're several options for installation:
- Python project only: Python framework for pose estimation (e.g., training, inference, refinement).
- ROS project for camera demonstration: ROS framework for object-level mapping with live cameras.
- ROS project for robotic demonstration: ROS framework for robotic demonstration with object-level mapping.
NOTE: We have developed this project on Ubuntu 16.04 (and ROS Kinetic, CUDA 10.1), so several code changes may be needed to adapt to other OS (and ROS, CUDA versions).
