Abstract: A method for photogrammetric texture mapping using casual images is provided. The method may include the following steps: estimating, for each vertex of at least a portion of a three dimensional (3D) mesh representing a model, projection parameters associated with a virtual camera that is unique for each vertex; mapping pixels from a two dimensional (2D) image to the vertices, such that each mapping of a pixel is based on the estimated respective virtual camera parameters; and texturing the portion of the mesh with corresponding mapped pixels wherein vertices on the textured portion are selected such that they are visible from a specified viewpoint associated with the 3D mesh.
