  • Publication number: 20230177723
    Abstract: The present invention relates to a method and an apparatus for estimating a user pose using a three-dimensional virtual space model. The method of estimating a user pose including the position and orientation information of a user for a three-dimensional space includes a step of receiving user information including an image acquired in a three-dimensional space, a step of confirming a three-dimensional virtual space model constructed based on spatial information including depth information and image information for the three-dimensional space, a step of generating corresponding information corresponding to the user information in the three-dimensional virtual space model, a step of calculating similarity between the corresponding information and the user information, and a step of estimating a user pose based on the similarity.

  • Patent number: 11516448
    Abstract: The projection image compensating method according to an embodiment of the present disclosure includes acquiring mesh data, at least one representative image, at least one supplementary image, and position information which is information about an obtaining pose of each image for an indoor space; adding an index of each of the plurality of faces to a matrix corresponding to a size of the at least one representative image in accordance with a result of projecting the plurality of faces which configures the mesh data to the at least one representative image; detecting at least one occluded face among the plurality of faces, using an index added to the matrix; and extracting pixel information which is information of a pixel value corresponding to the at least one occluded face from the at least one supplementary image.
