Embodiment Construction

[0018] Although several exemplary embodiments of the present invention are shown and described below, the present invention is not limited to the exemplary embodiments. Herein, the same reference numerals denote the same elements.

[0019] figure 1 The configuration of a guidance symbol display system according to an exemplary embodiment of the present invention is explained.

[0020] refer to figure 1 , the guide sign display system includes a user position extractor 110 , a sign position extractor 120 , a distance difference calculator 130 and a sign display controller 140 .

[0021] The user location extractor 110 extracts a current user location. In this case, the user location may be the location of the vehicle. Therefore, since the position coordinate value changes according to the movement of the vehicle, the current position coordinate value can be extracted.

[0022] The symbol location extractor 120 extracts symbol locations of symbols displayed for user conveni...

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.

Description

technical field [0001] The present invention relates to a system and method for displaying three-dimensional (3D) guidance symbols, and more particularly to a system and method for displaying guidance symbols in a screen having a size recognizable from a distance, And at the same time, provide the appropriate scale for the guidance symbols according to this distance. Background technique [0002] When the guide information is represented by a symbol image, the method for displaying the symbol may include a method of displaying the symbol image in screen coordinates by reflecting a position as a two-dimensional (2D) screen, reflecting the symbol position as a true three-dimensional (3D) map method and so on. In the first method, since the symbols are displayed on the screen at the same size regardless of the distance, the symbols are difficult to represent as structures in the map, but as simple symbol images. In the second method, since guidance information is inserted int...
