Disclosed herein is a location correction apparatus and method. The location correction apparatus includes a reference object search unit for searching a pre-stored geographic object database (DB) for one or more objects corresponding to objects included in a captured image and setting a reference object to be used to correct a location among the one or more objects that have been found. A reference point extraction unit sets reference points from the set reference object. A location determination unit obtains an actual distance between the reference points and calculates a location using the actual distance, a distance between the reference points included in the captured image, and metadata of the captured image. Therefore, the present invention can improve positioning accuracy and can be applied to high-quality location-based services or space information services thanks to the improved accuracy.

A virtual reality embodying system uses 2D images and HDRI data taken of a target object through a camera to embody virtual reality. A modeling unit compares the 2D image's coordinate with a real coordinate to calculate a transform matrix, calculates a vanishing point of a reference vector, uses the vanishing point to calculate a camera matrix, uses the camera matrix and the transform matrix to calculate a rotation matrix and a translation matrix, and uses the rotation matrix and the translation matrix to model the 2D image into a virtual model. A rendering unit uses the HDRI data as texture to render the virtual model, and embodies the HDRI into an extended VRML node to apply the virtual model to the VRML environment.
