The invention discloses a consistent lighting method under a falsehood-reality fused environment, comprising the following steps: shooting a
high dynamic range image reflecting a real environment, of a small mirror-surface sphere in a real scene, and acquiring an
environmental lighting map of the real scene; preprocessing the
environmental lighting map of the real scene and
surface reflection attributes of a virtual object; preprocessing the
environmental lighting of the real scene to generate environment lighting on a unit small sphere under local coordinates corresponding to all normal vectors to obtain
Haar wavelet coefficients of the environment lighting; preprocessing a bidirectional reflection
distribution function to generate slices of the bidirectional reflection
distribution function on the unit hemisphere under all
sight directions to obtain
Haar wavelet coefficients of the slices; and drawing a falsehood-reality fused environment, indexing the
wavelet coefficients of the environment lighting and the slices of the bidirectional reflection
distribution function according to a normal vector of an apex of the virtual object and the
sight directions, calculating a vector product of the coefficients to obtain an apex drawing color, and meanwhile, accelerating by adopting GPU (
Graphics Processing Unit). The consistent lighting method can be used for efficiently realizing afull-range environment lighting drawing effect under the falsehood-reality fused environment.
