Geographically guided generation of realistic 2D renders of 3D infrastructure models

A non-transitory computing device readable medium having instructions stored thereon, the instructions when executed by one or more computing devices operable to:

• receive a request to generate a realistic two-dimensional (2D) render of a three-dimensional (3D) infrastructure model;
• determine a viewpoint in 3D space of the 3D infrastructure model;
• generate a synthetic 2D render of the 3D infrastructure model from the viewpoint;
• obtain a set of style images that show terrain, vegetation, and/or structures;
• perform image translation to adjust visual appearance of infrastructure in the synthetic 2D render based on visual appearance of the set of style images and to generate realistic context based on what appears in the set of style images to produce the realistic 2D render;
• and
• output the realistic 2D render.

A method for assigning materials and/or textures to elements of a three-dimensional (3D) infrastructure model, comprising:

• receiving, by an application executing on one or more computing devices, a request to determine realistic materials and/or textures of the 3D infrastructure model;
• determining, by the application, a viewpoint in 3D space of the 3D infrastructure model;
• generating, by the application, a synthetic 2D render of the 3D infrastructure model from the viewpoint;
• generating, by the application, a location map that relates pixels in the synthetic 2D render to elements from which they were generated in the 3D infrastructure model;
• obtaining, by the application, a set of style images that show terrain, vegetation, and/or structures;
• performing, by the application, image translation to adjust visual appearance of infrastructure in the synthetic 2D render based on visual appearance of the set of style images based on what appears in the set of style images to produce the realistic 2D render;
• determining, by the application, realistic materials and/or textures for one or more elements of the 3D infrastructure model visible from the viewpoint based on the realistic 2D render and the location map;
• and
• updating, by the application, the 3D infrastructure model to add missing or replace initial materials and/or textures with the realistic materials and/or textures.
