Route modeling method and device based on cross section template

The invention provides a route modeling method and device based on a cross section template, and relates to the technical field of computer modeling, wherein the method comprises the steps: obtaining model parameter information of a cross section template model, and copying the cross section template model to each first path point; determining reconstruction model parameter information of the cross section template model on each first path point, and constructing a head-tail joint model and a longitudinal surface model composed of longitudinal surface grids between a front cross section and a rear cross section based on the parameter information; and finally, rendering the head-tail joint model and the longitudinal surface model to generate a target route model. According to the method, the technical problems that at present, all businesses related to the GIS need to be subjected to a modeling process of a BIM team, a user cannot autonomously create and modify the GIS model, the modeling difficulty is large,
