Researchers have introduced AirGroundBench, a new benchmark designed to evaluate the spatial intelligence of multimodal large language models (MLLMs) in collaborative air-ground scenarios. The benchmark addresses limitations in existing evaluations by focusing on heterogeneous views, scale mismatches, and reference-frame inconsistencies inherent in combined unmanned aerial vehicle (UAV) and unmanned ground vehicle (UGV) operations. Evaluations using AirGroundBench reveal that while current MLLMs perform adequately on basic spatial perception, they struggle significantly with cross-view alignment and transformation-intensive reasoning, impacting their sequential decision-making capabilities in vision-language navigation tasks.
