US Patent 10304241 Systems and methods for synthesising a terrain

A method and system for synthesising a terrain are provided. The method includes: providing access to multiple exemplar terrain templates and generating a working terrain image with target terrain dimensions and an associated working terrain height image. Generating the working terrain image includes sampling a plurality of the exemplar terrain templates for addition of the templates to the working terrain image, and performing image synthesis to improve the working terrain image including height matching the exemplar terrain samples. The method enables control of modification of the working terrain image by applying user-defined constraints to modify the synthesised terrain. The method outputs the working terrain image as a synthesised terrain in the form of a height-field.
