Abstract
A method of creating a three-dimensional model, based on two-dimensional (hereinafter “2D”) images is provided. The method includes acquiring a number of images of a number of physical locations, wherein each image is associated with one image group of a number of hierarchical image groups, the number of hierarchical image groups including a base image group, converting images within a group to a number of 3D models, wherein each 3D model is associated with one model group of a number of hierarchical model groups, the number of hierarchical model groups including a base model group, merging a number of the 3D models from the base model group and a number of 3D models from another 3D model group to create a multi-scale 3D model, and utilizing the multi-scale 3D model.
