The invention relates to the technical field of
anomaly detection, in particular to an intelligent gas hidden danger detection
system which comprises a leakage monitoring module, a
time difference extraction module, a direction positioning module, a
color temperature analysis module and a risk aggregation module. According to the method, the time and space relation of
gas concentration response nodes is extracted, a leakage
diffusion path is constructed, and a dominant propagation direction is identified, so that a leakage trend region has a clear positioning basis, regional brightness and
hue changes in an
image frame are combined, the
time sequence stability proportion is counted, and a cross-
modal trend
verification channel is established; the defect of a single sensing dimension is effectively made up, in the image and trend direction matching process, abnormal area numbers are recognized through stable proportion difference value changes, intersection confirmation is carried out on trend areas, the accuracy and spatial
directivity of hidden danger marking are remarkably improved, the risk recognition chain is more complete through cooperative calculation of multi-
source data, and the accuracy of hidden danger marking is improved. And the method has higher linkage response capability and dynamic judgment depth.
