Abstract: Under the background of military intelligence and the upsurge of the metaverse, with the support of such advanced technologies as cloud computing, artificial intelligence, and digital twins, around the demand for immersive aid decision-making, the immersive aid decision-making technology architecture from the perspective of metaverse has been preliminarily assumpted. The key elements of the physical layer, the application layer, the metaverse engine layer and the basic system layer of metaverse as the underlying support are summarized. The supporting technical methods for the metaverse engine layer are proposed, which has reference value for subsequent research on related technologies.
