摘要： Disclosed herein is an apparatus and method for extracting correspondences between aerial images. The apparatus includes a line extraction unit, a line direction determination unit, a building top area extraction unit, and a correspondence extraction unit. The line extraction unit extracts lines corresponding buildings from aerial images. The line direction determination unit defines the directions of the lines as x, y and z axis directions based on a two-dimensional (2D) coordinate system. The building top area extraction unit rotates lines in the x and y axis directions so that the lines are arranged in parallel with the horizontal and vertical directions of the 2D image, and then extracts building top areas from rectangles. The correspondence extraction unit extracts correspondences between the aerial images by comparing the locations of the building top areas extracted from the aerial images.

摘要： A method for reconstructing a 3D shape model of an object by using multi-view image information, includes: inputting multi-view images obtained by photographing the object from multiple viewpoints in a voxel space, and extracting silhouette information and color information of the multi-view images; reconstructing visual hulls by silhouette intersection using the silhouette information; and approximating polygons of cross-sections of the visual hulls to a natural geometric shape of the object by using the color information. Further, the method includes expressing a 3D geometric shape of the object by connecting the approximated polygons to create a mesh structure; extracting color textures of a surface of the object by projecting meshes of the mesh structure to the multi-view image; and creating a 3D shape model by modeling natural shape information and surface color information of the object.

摘要： Provided are system and method for generating a 3D facial model and animation using one video camera. The system includes a pre-processing part, a facial model generating part, a transferring part, a projecting part, an error calculating part, and a mesh transforming part. The pre-processing part sets correspondence relations with other meshes, generates an average 3D facial model, and generates a geometrical model and a texture dispersion model. The facial model generating part projects the average 3D facial onto an expressionless facial image frame that stares a front side to generate a performer's 3D facial model. The transferring part transfers a 3D facial model template having an animation-controlled model to the performer's 3D facial model to generate the performer's 3D facial model. The projecting part projects the performer's 3D facial model onto a facial animation video frame including a facial expression. The error calculating part calculates an error projected by the projecting part. The mesh transforming part moves or rotationally converts a joint in such a direction as to minimize the error.
