MULTI-STAGE METHOD OF GENERATING 3D CIVIL SITE SURVEYS

摘要

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.

1. A method of creating a three dimensional model based on two dimensional images comprising:
acquiring a number of images of a number of physical locations, wherein each said image is associated with one image group of a number of hierarchical image groups, said number of hierarchical image groups including a base image group and a top image group; converting images within a group to a number of 3D models, wherein each said 3D model is associated with one model group of a number of hierarchical model groups, said number of hierarchical model groups including a base model group and a top model group; merging a number of said 3D models from said base model group and a number of 3D models from another 3D model group to create a multi-scale 3D model; and utilizing said multi-scale 3D model.
