The application belongs to the field of airport management, and relates to a smart video
inspection method and
system based on a multi-
modal large model, which comprises the following steps: 1, based on unstructured text in airport data, a structured
knowledge graph is constructed, and a high-dimensional
semantic vector is obtained based on nodes of the structured
knowledge graph; 2,
feature extraction is performed on various data including monitoring video to generate multi-
modal joint feature representation; the multi-
modal joint feature representation comprises space-
time information and rule context; 3, based on the high-dimensional
semantic vector and the multi-modal joint feature representation, it is judged whether an abnormal event occurs in the terminal building; 4, if an abnormal event occurs, a structured instruction is generated based on the abnormal event, and the terminal building is optimized in a
closed loop based on the structured instruction; based on the existing
video monitoring environment and data of the airport, an integrated intelligent
system is provided for intelligent inspection of the terminal building, and
automation, refinement and closed-loop management of the inspection are realized.
