20110148864 | METHOD AND APPARATUS FOR CREATING HIGH-QUALITY USER-CUSTOMIZED 3D AVATAR - Disclosed herein is a method and apparatus for creating a 3D avatar. The method of creating a three dimensional (3D) avatar includes receiving body information of a user and storing the body information in a DataBase (DB), and creating a 3D avatar for the user by modifying standard data, predetermined based on body information about various persons and stored in the DB, based on the body information of the user. | 06-23-2011 |
20110148874 | SYSTEM AND METHOD FOR TRANSFORMING MUSCLES OF CHARACTER MODEL - Disclosed herein is a method and system for transforming the muscles of a character model. The muscles of a target model are created using the muscle information of a reference model. The system includes a reference model processor and a target model processor. The reference model processor creates a reference feature volume, that is, a 3D geometric shape, based on the skeleton and appearance information of the reference model, and subordinates the muscle information of the reference model to the feature volume. The target model processor deforms the reference feature volume to be suitable for the target model, and applies the muscle information of the reference model to the target model, thereby creating muscles for the target model based on the extent of the deformation of the reference feature volume. | 06-23-2011 |
20120155745 | APPARATUS AND METHOD FOR EXTRACTING CORRESPONDENCES BETWEEN AERIAL IMAGES - 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. | 06-21-2012 |
20120162215 | APPARATUS AND METHOD FOR GENERATING TEXTURE OF THREE-DIMENSIONAL RECONSTRUCTED OBJECT DEPENDING ON RESOLUTION LEVEL OF TWO-DIMENSIONAL IMAGE - 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. | 06-28-2012 |
20130207966 | APPARATUS AND METHOD OF PRODUCING 3D MODEL - Disclosed are an apparatus and a method of producing a 3D model in which a 3D model having a static background is produced using a point cloud and an image obtained through 3D scanning. The apparatus includes an image matching unit for producing a matched image by matching a point cloud obtained by scanning a predetermined region to a camera image obtained by photographing the predetermined region; a mesh model processing unit for producing an object positioned in the region as a mesh model; and a 3D model processing unit for producing a 3D model for the object by reflecting texture information obtained from the matched image to the mesh model. The disclosed may be used for a 3D map service. | 08-15-2013 |
20140112574 | APPARATUS AND METHOD FOR CALIBRATING DEPTH IMAGE BASED ON RELATIONSHIP BETWEEN DEPTH SENSOR AND COLOR CAMERA - Disclosed is a method of calibrating a depth image based on a relationship between a depth sensor and a color camera, and an apparatus for calibrating a depth image may include a three-dimensional (3D) point determiner to determine a 3D point of a camera image and a 3D point of a depth image simultaneously captured with the camera image, a calibration information determiner to determine calibration information for calibrating an error of a depth image captured by the depth sensor and a geometric information between the depth sensor and a color camera, using the 3D point of the camera image and the 3D point of the depth image, and a depth image calibrator to calibrate the depth image based on the calibration information and the 3D point of the depth image. | 04-24-2014 |
20140218354 | VIEW IMAGE PROVIDING DEVICE AND METHOD USING OMNIDIRECTIONAL IMAGE AND 3-DIMENSIONAL DATA - A view image providing device and method are provided. The view image providing device may include a panorama image generation unit to generate a panorama image using a cube map including a margin area by obtaining an omnidirectional image, a mesh information generation unit to generate 3-dimensional (3D) mesh information that uses the panorama image as a texture by obtaining 3D data, and a user data rendering unit to render the panorama image and the mesh information into user data according to a position and direction input by a user. | 08-07-2014 |
20140245231 | PRIMITIVE FITTING APPARATUS AND METHOD USING POINT CLOUD - A primitive fitting apparatus is provided. The primitive fitting apparatus may include a selecting unit to receive, from a user, a selection of points used to fit a primitive a user desires to fit from a point cloud, an identifying unit to receive a selection of the primitive from the user and to identify the selected primitive, and a fitting unit to fit the primitive to correspond to the points, using the points and primitive. | 08-28-2014 |
