摘要： An approach is provided for accurate processing and registering of media content for rendering in 3D maps and other applications. The approach includes determining at least one first pixel of at least one image that geometrically corresponds to at least one second pixel of at least one rendered three-dimensional map. Further, the approach includes processing and/or facilitating a processing of (a) the at least one first pixel; (b) the at least one second pixel; (c) metadata associated with at least one of the at least one first pixel and the second pixel; or (d) a combination thereof to determine at least one confidence value, wherein the at least one confidence value is indicative of an estimated level of geometric distortion resulting from projecting the at least one first pixel onto the at least one second pixel. Furthermore, the approach includes determining whether to cause, at least in part, a rendering of the at least one first pixel onto the at least one rendered three-dimensional map based, at least in part, on the confidence value.

摘要： A method and technical equipment are provided. The method comprises receiving media content comprising images and depth information; generating a sparse voxel octree from the received images and depth information; projecting the received image colors to each voxel of the generated sparse voxel octree based on visibility; converting the received images into a set of radiance samples for each voxel of the generated sparse voxel octree; and processing the radiance samples by performing one of the following: fitting the radiance samples to a parametric color model to generate estimated radiance samples for a current viewing direction; or analyzing the radiance samples with the content of the generated sparse voxel octree to separate an actual surface color and reflectance properties from a reflected lighting.
