Abstract: Highlights•We discuss group activity recognition in three-dimensional space, the problem of occlusion in group are solved.•This work is combined with 3D backbone and RGB feature, and we deeply study the spatiotemporal relationship between individuals.•In the process of establishing the relationship graph, the unified spatial temporal graph (USTG) is used to break through the spatiotemporal limitation.
