In the field of computer vision, multimodal large language models (MLLMs) have demonstrated strong image understanding and reasoning capabilities. However, when dealing with multiple images from different perspectives, existing models often struggle to establish accurate spatial correspondences. Cross-view spatial reasoning involves complex tasks such as object correspondence, visibility judgment, geometric relationship understanding, and physical reasoning, which places higher demands on MLLMs.
Traditional multi-image processing methods usually simplify the problem to general multi-image fusion, but this approach ignores the spatial correlations between perspectives. The CrossView Suite project addresses this research gap by proposing a systematic solution.
