Unreal Engine Multi-View RGB-D Lunar Rock Dataset for 3D Segment Correspondence in Complex Scenes

This dataset contains synthetic multi-view lunar rock scene observations generated in Unreal Engine 5.5 using eight synchronized camera viewpoints per scene. For each viewpoint, the dataset provides RGB images, floating-point depth maps, and semantic annotations, enabling joint analysis of visual appearance, 3D geometry, and scene-level labeling. The dataset is intended to support research in lunar environment perception, RGB-D scene understanding, semantic segmentation, and multi-view 3D segment correspondence.
