Augmented lighting environments

摘要

A method and apparatus for rendering the lighting of virtual objects in an augmented reality display. The method includes determining local and ambient light sources based on data provided by one or more light sensors. The light in the physical lighting environment is accounted for by attributing the light to local light sources and/or ambient light sources. A synthesized physical lighting environment is constructed based on the light characteristics of the local and/or ambient light sources, and is used in properly rendering virtual objects in the augmented reality display.

1. A method of rendering a display, the method comprising:
identifying at least one local light source based on data related to the physical lighting environment that is received from a first sensor; measuring a first light characteristic of the at least one local light source in a physical lighting environment; determining movement and orientation of the at least one local light source based on the at least one light characteristic of the at least one local light source with respect to the light sensor and further based on movement and orientation of the first light sensor; estimating a second light characteristic of at least one ambient light source based on light in the physical lighting environment not attributable to a local light source; forming a synthesized lighting environment based at least on the first light characteristic and the second light characteristic; and rendering a virtual object in an augmented reality display, wherein the lighting of the virtual object is based on the synthesized lighting environment.
