Abstract

Sudden leakage has become a growing threat to public safety in cities. In our study, constructing a model of three-dimensional dynamic diffusion of leaked pollution gas, and exploring key technologies for space-time evolution of leakage diffusion, we implemented the visual processing of positioning and monitoring of regional pollution and also implemented the visual presentations and interpretation of pollutant diffusion data. Therefore, it can provide decision-making and ancillary support for emergency relief.
