摘要：
A method for creating a three-dimensional mesh model of a structure includes accessing a set of three-dimensional points associated with a set of images of the structure. For each three-dimensional point in the set of three-dimensional points, the method determines a reference image, identifies a subset of images from the set of images of the structure taken within a distance from the reference image, determines a subset of three-dimensional points seen by the subset of images, filters the subset of three-dimensional points to retain only a set of co-visible points that lie in a visibility cone of the reference image, and selects a normal using the set of co-visible points. The three-dimensional mesh model of the structure is computed using the selected normal, and the model may be provided to a second computing device.
