A vision-based marker-less pose estimation system for

Both 2D and 3D pose are estimated. The system is trained with image datasets collected from a robotic excavator and annotations of excavator pose, as well as conventional excavators working on construction sites. A KUKA robot arm with a bucket mounted on the end-effector was used to represent the robotic excavator in the experiments.
