The invention belongs to the technical field of intelligent monitoring, and particularly relates to a 5G
Internet of Things fused
video monitoring intelligent early warning method, which comprises the following steps of: acquiring vehicle attribute information and environment
perception data, constructing a 5G
Internet of Things perception network, fusing a vehicle movement track and
road condition environment data through a cross-
modal attention mechanism, generating an enhanced environment
perception graph, and simultaneously, carrying out early warning on the vehicle movement track and the
road condition environment data. Optimizing the transmission efficiency by adopting a
dynamic resolution adjustment
algorithm; the method comprises the following steps: constructing a dynamic behavior prediction model by using a space-time diagram convolutional network, predicting a vehicle abnormal behavior probability and an evolution trajectory, calculating an early warning level through an adaptive
risk quantification algorithm, simulating a risk
diffusion coefficient by using a dynamic risk propagation model according to the road section vehicle density, the average vehicle speed and the
road traffic capacity, and correcting early warning sensitivity parameters in real time. And transmitting to a command platform, performing situation deduction, triggering a grading early warning instruction, and generating thermodynamic diagram warning information. Therefore, the problems of insufficient positioning precision, weak analysis capability, poor transmission efficiency and the like in the prior art are solved.
