Embodiment Construction

[0062] The following detailed description of the invention first provides an overview of this innovative technology and then discloses an embodiment of generating a three-dimensional model of a human body part for trying on clothes.

[0063] Technical overview of the invention:

[0064] The technique of the present invention provides a solution to the problem of generating a three-dimensional model of an object's surface under certain circumstances. These are cases where the model has specific accuracy requirements and there are not enough elements in the resulting image of the surface being modeled to extract enough correlable features to provide interrelatable features that meet the model accuracy requirements. A certain density of associated features.

[0065] The above problems are solved by imposing a visual pattern on the surface being modeled. Such patterns provide sufficient extractable features for the aforementioned practical applications, and further provide featu...

Abstract

The invention provides techniques which employ structure-from-motion modeling techniques to produce 3-D models of any desired accuracy of any surface. In 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.

Description

Technical field: [0001] The present invention relates to techniques for extracting information from a three-dimensional surface and generating a three-dimensional model of the three-dimensional surface. Applications of this technology include generating 3D models of human body parts that can be used to select sizes for mass-produced or custom-made garments. Background technique: [0002] There are several methods for generating mathematical models from 3D surfaces. These technologies have many possible applications; however, generating accurate 3D models using these technologies is too difficult and / or expensive for the average consumer, so in applications such as choosing or trying on clothes, these technologies Also too difficult and / or expensive to use. [0003] Difficulties in modeling the shape of objects such as the human body: [0004] Object shape modeling, such as modeling human body parts for the purpose of trying on clothes, is a difficult problem. Many of the...
