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： The present invention relates to an apparatus and method for generating a texture of a 3D reconstructed object depending on a resolution level of a 2D image. The apparatus includes a 3D object reconstruction unit for extracting, from images captured from at least two areas located at different distances, information about a 3D object and information about cameras, and then reconstructing the 3D object. A resolution calculation unit measures size of a space area, covered by one pixel of each of the images in a photorealistic image of the 3D object, and then calculates resolutions of the images. A texture generation unit generates textures for respective levels corresponding to classified images by using the images classified according to resolution level. A rendering unit selects a texture for a relevant level depending on a size of the 3D object on a screen, and then renders the selected texture.
