Abstract: The present invention relates to a method and system for selectively blending buildings to improve route visibility in a 3D navigation system. A method for displaying a 3D map may include: detecting whether or not an object to be displayed on a map screen intersects with a route guiding line on the map screen with the object intersecting the route guiding line being blended therewith.

Abstract: A system and method of displaying a three-dimensional (3D) map based on road information. A display system, including: a culling area determination unit to determine a culling area based on road information; a data conversion unit to convert data of at least a portion of objects displayed on the culling area; and a display unit to display at least the portion of the objects based on the converted data.

Abstract: A display system and method using texture mapping is provided. The display system, including: a texture maintenance unit maintaining a texture generated based on a characteristic of an object; a texture selection unit selecting a texture based on an object to be displayed; and a texture application unit repeatedly applying the selected texture to at least a portion of a three-dimensional (3D) texture corresponding to the object to be displayed.

Abstract: Disclosed are a system and a method of displaying a guidance symbol. The guidance symbol displaying system may include a distance difference calculator to calculate a distance difference between a user location and a guidance symbol location, and a symbol display controller to control display of the guidance symbol by calculating a size of the guidance symbol based on the distance difference.

Abstract: A method for estimation of a fundamental matrix by selecting sets of correspondence points is provided. According to the method, an entire image is divided into several sub-regions, and the number of the inliers in each sub-region and the area of each region is examined. The standard deviation are used as quantitative measures to select a proper inlier set. This method achieves a more precise estimation of the fundamental matrix than conventional method does.
