[0004] However, the building 3D model established by the prior art only includes the shape data of the building, and the propagation of electromagnetic waves depends not only on the shape of the building, but also on factors such as the material of the building. Therefore, the existing 3D building model can only be used for In the field of unmanned driving and navigation, it cannot be directly applied to the simulation of urban electromagnetic environment

The invention discloses a rapid urban environment modeling method for electromagnetic calculation, comprising: step A: using laser radar and optical camera to scan the modeling area, and establishing the inclusion of the modeling area according to the scanned laser point cloud image and optical image Dense point cloud image of electromagnetic material information; step B: according to the category corresponding to the electromagnetic material information of each point in the dense point cloud, segment the point cloud in the dense point cloud image to obtain the entity composed of point cloud; step C: for each The geometric structure of the entity recognizes the characteristics of each object, and uses the characteristics of each object to fit the reconstruction model of the entity, and then establish a three-dimensional model of the city. By applying the method of the invention, a three-dimensional model suitable for electromagnetic calculation can be established.
Description
technical field [0001] The invention relates to the technical field of electromagnetic environment simulation, and more particularly relates to a rapid urban environment modeling method for electromagnetic calculation. Background technique [0002] The urban electromagnetic radiation environment is an important environmental factor. In the past 20 years, the development and application of electromagnetic technology has become increasingly widespread, and the impact on the surrounding environment and human health has become increasingly serious. Detection is given great importance. For urban electromagnetic environment monitoring, obtaining high-precision 3D images of the urban area to be monitored is a necessary prerequisite. [0003] In the prior art, methods for acquiring high-precision 3D images of urban areas mainly include: satellite surveying and mapping, and airborne lidar surveying and mapping. However, the traditional satellite surveying and mapping image technolo...
