A lightweight color and geometry feature extraction and fusion module for end-to-end 6D pose estimation

International Journal of Advanced Robotic Systems
Although advancements in red–green–blue-depth (RGB-D)-based six degree-of-freedom (6D) pose estimation methods, severe occlusion remains challenging. Addressing this issue, we propose a novel feature fusion module that can efficiently leverage the color ...
