Abstract: A stereoscopic image output system includes a stereoscopic vision output unit, an image database storage unit, and an output control unit. The stereoscopic vision is realized by outputting, from the stereoscopic vision output unit, a left-eye image and a right-eye image with parallax such that the left and right-eye images are visually recognized by the left and right eyes, respectively. Left-eye parallel projection data and right-eye parallel projection data are generated by parallel projection of a three-dimensional model using respective projection angles set for the left eye and right eye so as to produce the parallax therebetween, and stored in the database storage unit as two-dimensional drawing data. The output control unit controls an output range of the left and right-eye images. If the output range for the stereoscopic image changes, moving directions of the left-eye image and the right-eye image are individually determined by the output control unit.

Abstract: A stereoscopic map display system includes (a) a stereoscopic vision display unit for providing a stereoscopic vision by displaying a right-eye image and a left-eye image with parallax so as to be visually recognizable by the right eye and the left eye, respectively, (b) a map database storage unit for storing map data, and (c) a display control unit for providing the right-eye image and the left-eye image at least part of which has the parallax, to the stereoscopic vision display unit based on the map data. The map data stores feature data indicating a shape of a feature and a display-depth adjusted object indicating an object other than the feature and displayed by a display depth under a predetermined rule. The display control unit displays the display-depth adjusted object with the multi-staged display depths under a predetermined rule for an attribute or a display position thereof.

Abstract: A three-dimensional map display system displays a three-dimensional map representing features thereon three-dimensionally. The system includes a map database, a projection view generation unit, and an attribute representation image superimposing unit. The map database stores drawing data including a three-dimensional model of a feature and appearance attribute information representing an appearance attribute of the feature, by associating the drawing data and the appearance attribute information with each other. The projection view generation unit generates a projection view by projecting the drawing data.

Abstract: A route guidance device is provided with a two-dimensional road network for a route search, a three-dimensional road network for a route guidance, and guiding line shape data. The guiding line shape data is three-dimensional guidance display data for guiding an operator to go straight through, or to make a right turn, left turn, etc. at intersections in accordance with a passage mode, or to switch lanes before entering an intersection. A link node of the two-dimensional road network is associated with the guiding line shape data through the three-dimensional road network. The route search uses the two-dimensional road network, and the route guidance uses the guiding line shape data associated with the link node acquired by the route search. The present invention can realize an instinctively understandable route guidance that follows a passage mode without increasing a load of a route search.

Abstract: A three-dimensional map is provided by preserving its scale. The three-dimensional map is drawn based on prepared landscape feature data which three-dimensionally draws roads, buildings, and other landscape features. The landscape feature data is generated by a parallel projection method which projects an actual landscape feature (CST2) upon a projection plane (PL2) with parallel lines along the projection direction (PRJ), rather than a perspective projection. The landscape feature data is provided by either two-dimensional raster data or polygonal data that draws a parallel projected projection map. It is possible to draw the three-dimensional map by only drawing the prepared landscape feature data, without rendering or other load-intensive processing. Unlike the perspective projection, the parallel projection preserves the positional relationships among buildings and the scale of shapes, so as to provide a three-dimensional map in which the scale is preserved.

Abstract: It is an object to realize a route guidance that follows a real passage mode without a feeling of wrongness. In a route guidance device, aside from a two-dimensional road network for a route search, a three-dimensional road network used for the route guidance and guiding line shape data are prepared. The guiding line shape data are three-dimensional guidance display data that guide you to go straight through a crossroads, to turn right, to turn left, etc. in accordance with a passage mode or guide you to change a car lane before you enter a crossroads. A link node of the two-dimensional road network is associated with the guiding line shape data through the three-dimensional road network. The route search is carried out by using the two-dimensional road network. The route guidance is carried out by using the guiding line shape data associated with the link node acquired by the route search.
