This application discloses a hierarchical adaptive intelligent association and alignment method for multimodal
flight data, comprising: acquiring multi-source airborne
flight data and preprocessing it; mapping data of different
modes in the preprocessed multi-source airborne
flight data to a common feature space to obtain cross-
modal alignment features, wherein an aircraft physical dynamic model is introduced as a constraint during the mapping process; performing local precise association and global
semantic association in parallel based on the cross-
modal alignment features; wherein the local precise association is used to obtain pixel-level or point-level matching results, and the global
semantic association is used to obtain globally consistent
semantic association results; and fusing the results of the local precise association and the global semantic association to obtain association information of corresponding
granularity. This invention effectively solves the "data
silo" problem caused by differences in format, spatiotemporal reference, and modality of multi-source flight data, significantly improving association accuracy, robustness, and
system adaptability.
