Abstract:
Techniques described herein are directed to a system and methods for generating 3D models of an object which accurately depict reflective properties of the object. To do this, an image of an object is captured and a rendered image of the object is generated from the image. The system then generates a lighting effect which approximates an effect of the actual light source on the appearance of the object when the image was captured. A number of rendered images of the object are generated using the lighting effect, each having different visual material property values. Once the rendered images have been generated, the system may compare the generated rendered images to the actual image in order to identify the rendered image which best approximates the actual image. The visual material property values associated with the best approximation are then assigned to the object.

Claim (Index 1):
A method of generating a three-dimensional (3D) model, comprising:\n receiving, by a computer system, a captured image of an object under specified lighting conditions; identifying, by the computer system, a section of the object based on the captured image; for at least the first section of the object, performing operations that comprise: generating, in accordance with the specified lighting conditions, a collection of rendered images, each of the rendered images having a combination of at least X different material properties where X is an integer greater than 1, the collection of rendered images being rendered such that:\n from a first of the rendered images to an N th  of the rendered images in the collection of rendered images, a first of the X different material properties remains constant whereas the other one or more different material properties appear in varying combinations of values from the first of the rendered images to the N th  of the rendered images, \n from a (N+1) th  of the rendered images to a K th  of the rendered images, a second of said X different material properties remains constant whereas the other one or more different material properties appear in varying combinations of values from the (N+1) th  of the rendered images to the K th  of the rendered images, \n and if X is greater than 2, a (K+1) th  of the rendered images to a J th  of the rendered images include a subset of the rendered images for each of the X material properties other than the first and second material properties, the rendered images in each subset having a constant value of the material property that corresponds to that subset and varying combinations of values for the other X\u22121 material properties, the variations in combinations of values being selected so that there is a rendered image in the collection of rendered images for each possible combination of values among the different material properties and such that each rendered image is rendered with a lighting effect that approximates or simulates an effect of the light source on an appearance of the object with the specified combination of values for the material properties; \n comparing each of the individual rendered images of the combination of rendered images to the captured image; \n calculating an image error based on the comparison between each individual rendered image and the captured image; and \n assigning a visual material property value associated with the individual rendered image to the section based upon the image error.
