1. A method for validating the accuracy of three-dimensional models, comprising: accessing one or more three-dimensional models of a structure; accessing at least one real world image of said structure wherein said at least one real world image has an imaging plane; combining features of said one or more three-dimensional models of said structure with features of said at least one real world image of said structure to create a composite model of said structure wherein said composite model comprises features of a three-dimensional model of said structure and features of a real world image of said structure; projecting said composite model into said imaging plane of said at least one real world image; comparing said composite model of said structure that is projected into said imaging plane of said at least one real world image with at least one of said at least one real world images; and based on said comparing, determining the accuracy of said one or more three-dimensional models of said structure.
