Method for generating an environment map

摘要

An environment map representative of lighting information of a real environment. As to enhance the impression of immersion into a virtual environment, the method comprises the steps of acquisition at real time of an image representative of a partial lighting information of said real environment from a digital optical acquisition device, said image comprising a plurality of pixels; and estimation of said environment map by extrapolation of at least a part of said pixels of said image, the extrapolation comprising the application of a first value corresponding to the mean value of the pixels of said image to at least a first part of the environment map.

1. A method of generating an environment map representative of lighting information of a real environment, comprising:
acquiring in real time an image representative of a partial lighting information corresponding to a partial representation of said real environment from an image acquisition device, said image comprising a plurality of pixels, generating said environment map by:
applying said partial lighting information to a first part of the environment map;applying values of pixels of a border of said image to at least a second part of the environment map, the second part being different from the first part; andapplying a value corresponding to a mean value of at least a part of the pixels of said image to a third part of the environment map, said third part being different from the first part and the second part.
