The invention discloses a real-time monitoring video and three-dimensional scene fusion method based on a three-dimensional GIS (Geographic Information System), which belongs to the technical field ofthree-dimensional GIS, and comprises the following steps: S1, inputting model data, checking texture and triangular patch number of an artificial modeling model by using hypergraph iDesktop software,removing repeated points, converting a format to generate a model data set, and storing the model data set in a database; performing root node combination and texture compression on the original OSGBformat data by the inclination model; and S2, converting the model data set and the inclined OSGB slice into a three-dimensional slice cache in an S3M format. The live-action fusion method disclosedby the invention is oriented to the fields of public security and smart cities, avoids the application limitation of the traditional two-dimensional map and monitoring video, solves the disadvantage that the monitoring video pic
