Abstract

Paired images of substantially the same scene are captured with the same freestanding sensor. The paired images include reflected light illuminated with controlled polarization states that are different between the separate images. A first pixel value from one of the first image and the second image is subtracted from a corresponding pixel value from a remaining one of the first image and the second image. When repeated over the raster of corresponding pixels, a modified image includes an isolated representation of substantially pure specular color data. The captured images and the modified image are stored and used to generate a model. Substantially shadow-free diffuse color and specular color data are applied to texture maps of the model to generate a virtual environment where a virtual light source can be introduced and controlled to achieve desired results absent adverse effects introduced from fixed ambient light sources used in conventional source photography.

Dependent claims

A method for processing image information, the method comprising:

receiving a sensor orientation, the sensor orientation defining a sensor axis;
receiving a data set responsive to a cross-polarized exposure, wherein subject matter captured in the cross-polarized exposure is illuminated with light provided by an image capture system, the light provided by the image capture system forming an angle of less than about 10 degrees from the sensor axis to provide a diffuse surface texture;
wherein the cross-polarized exposure is captured with an image-capture system fixed to a freestanding chassis;
using the diffuse surface texture in the data set and the sensor orientation to generate a UV map;
receiving a preferred orientation;
rendering a virtual environment using the preferred orientation, the three-dimensional model and color information from the data set;
receiving information characterizing a virtual light source;
and
modifying the virtual environment in response to the virtual light source;
wherein information characterizing the virtual light source includes one or more of identifying a location, a luminous flux, and a frequency range.
