Systems and methods for generating dimensionally coherent training data

Abstract

System and method are provided for generating training data for feature matching among images of a building structure. The method includes obtaining a model of a building that includes a camera solution and images used to generate the geometric model. The method also includes, for facades of the model: applying a minimum bounding box to a respective facade to obtain a respective facade slice that is a 2-D plane represented in a 3-D coordinate system of the model; and projecting visual data of at least one camera in the camera solution that viewed the respective facade onto a visibility mask associated with the respective facade slice. The method also includes photo-texturing the projected visual data facade slice to one of the facade slices or the geometric model to generate a visual 3-D representation of the building; and generating a training dataset by perturbing the visual 3-D representation.
