Abstract: Images are made of a surface, and images are made of a covering (in the form of a reference object) having a pattern that includes an array of locally non-repetitive pattern elements. A three-dimensional models of the pattern elements on the covering is created using the images. A correlation in scaling between the process of generating three-dimensional models of the pattern elements on the covering and the process of generating a three-dimensional model of the surface is known, and this known correlation in scaling and the known actual distances among pattern elements on the covering can be used as a dimensional scale reference to determine dimensional information of the three-dimensional model of the surface.

Abstract: Techniques which employ structure-from-motion modeling techniques to produce 3-D models of any desired accuracy of any surface I the techniques, a pattern is applied to the surface to be modeled The pattern includes elements which are unique within the pattern as applied to the surface and which have a density in the pattern such that when two-dimensional images are made of the surface, correlatable features having the density required for the desired accuracy may be extracted from the two dimensional images In one example of the techniques, a consumer may make the images required to produce a model of his or her body by donning a garment with a pattern having the necessary uniqueness and density, and then using any digital camera to take pictures of their body wearing the garment The model may then be produced from the pictures.
