The application discloses a kind of multi-
modal event primitive extraction, coding and collaborative generation method and
system for smart
engineering construction scene, the
system includes multi-
modal data acquisition module, edge preprocessing module, event candidate extraction module, time-space alignment module, subject association module, event primitive coding module, multi-source fusion generation module and primitive output module. Through edge pre-
processing, candidate event extraction,
time alignment,
space mapping, subject association, unified coding and multi-source fusion to video, environmental parameters,
device status, positioning information, wearable terminal data and job
log data and other multi-
modal raw data, generate standardized event primitives, and output to
risk identification,
knowledge graph and early warning module. The present application can reduce the transmission pressure of
raw data, improve the unified semantic expression ability of multi-source heterogeneous data, the fusion accuracy and the subsequent risk analysis efficiency, suitable for hoisting, high altitude,
closed space and warehousing logistics and other smart
engineering construction scenes.
