Description of the Invention: [Technical Field] The present invention relates to a face display technology for a map for navigation, and more particularly to a method and system for stereoscopic display of a map for navigation. [Prior Art] Among the currently available navigation products, whether it is a portable (p〇rtat)le navigation device or a personal computer (PC) version of the program, there is a ‘three-table (3D) mode to choose from. However, as shown in FIG. ,, the screens 11 to 13 displayed on the existing navigation map are actually only a bird's-eye view mode plus a map rotation function, and the plane data such as roads and rivers are deformed, so that the user has the illusion of depth of field. To achieve its '3D, the effect. In fact, this is just to view the flat map image for different angles. There is no real ‘3〇, the object map is in the map screen. Therefore, it is necessary to seek a solution to truly align the map image so that it is no longer limited to the map data on the flat data and more suitable for the actual road conditions. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a book surface stereoscopic method for navigation. - Thus, the method for stereoscopically drawing a map for navigation according to the present invention comprises the steps of: (a) generating at least a three-dimensional object map using the stereoscopic data set. Integrating the three-dimensional object map on the navigation map; (1) if located When the three-dimensional object map of the foreground and the road information of the current map of the user at least partially overlap, the three-dimensional object map is transparently processed by 200926059; and (d) will be integrated and already The navigation map for performing the required transparency processing is displayed to a user. Another object of the present invention is to provide a picture stereoscopic system for navigation maps. Therefore, the three-dimensional system of the navigation map of the present invention comprises a stereoscopic module, an integrated module, a transparent module, and a display module. The stereoscopic module is configured to generate at least one three-dimensional object map by using a stereoscopic data set. The integration module is configured to integrate the three-dimensional object map on the navigation map. The transparent module is configured to determine whether the three-dimensional object map located in the foreground overlaps with the road information of the current position of the user on the navigation map, and if so, the three-dimensional object map is transparently processed. The display module is configured to display the navigation map that has been integrated and has been subjected to the required transparency processing to a user. The three-dimensional map of the navigation map can be stereoscopically obtained by the present invention, and the object of the present invention can be achieved. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to FIG. 2 and FIG. 4, a preferred embodiment of the three-dimensional three-dimensional system for navigation of the present invention comprises a stereoscopic module 21, a stereoscopic database, an integrated module 23, and a transparent module 24. And a display module. In the preferred embodiment, an embodiment of the present invention is an electronic 6 200926059 device or a vehicle-mounted navigation dedicated device for navigating a mobile phone, a personal digital assistant (PDA), or the like. 21, the integrated module 23, and the transparent module 24 can be integrated into the navigation device stereoscopic software installed to the electronic device; but the stereoscopic module 21, the integrated module 23, and the transparent The module 24 can also be integrated into a PC version program and installed on the PC side of the user, and is not limited to the preferred embodiment. The stereoscopic module 21 is configured to generate at least one three-dimensional object map by using a stereoscopic data set, and the three-dimensional data set and the three-dimensional object map are stored in the three-dimensional data base 22. The three-dimensional data set includes information required for three-dimensionalization, that is, a building stillness, a block height, a building appearance, and a building shape. The integration module 23 is configured to integrate the stereoscopic data set and the three-dimensional object map on the navigation map 4. The transparent module 24 is configured to determine whether the three-dimensional object map located in the foreground overlaps at least partially with a road information of the current position 42 of the user on the navigation map 4, and if so, the three-dimensional object map is transparent deal with. The display module 25 is for displaying the navigation map 4 that has been integrated and has been subjected to the required transparency processing to the user. Referring to Figures 2, 3 and 4, in accordance with the preferred embodiment described above, the method for stereoscopically viewing a map for navigation uses the following steps. In the step 31, the stereoscopic module 21 generates the three-dimensional object map by using the height of the building, the height of the block, the appearance of the building, and the shape of the building; the three-dimensional object map may be pre-established and stored in the stereoscopic database 22, or It is only generated when it is intended to be displayed, depending on the system performance adopted by the developer of the present invention. The three-dimensional module 21 is configured to vertically shift the 200926059 building degree ' according to an original outer frame to generate a building stereoscopic image. The height of the building may be the number of building floors; similarly, the three-dimensional The module is configured to generate a block perspective view 43 according to the upward displacement of the block height according to an original block; the three-dimensional object view includes the building perspective view 41 and the block perspective view 43. The stereographic module 21 uses the shape of the building to shape the shape of the stereogram of the building to generate a stereoscopic view 41 of the real shape. The shape of the structure may be a regular triangular pyramid, a sphere, or the like. Similar to the tree 〇 _ irregular shape. The three-dimensional module 21 can also attach the perspective view of the building to the appearance of the building to generate a stereoscopic view of the building that presents a real appearance: the appearance of the building can be the material of the building (for example, 'brick, cement, glass curtain, etc. ), the color of the building, a specific appearance, and user-defined styles. In step 3", the integration module 23 integrates the stereoscopic data set and the three-dimensional object map into the navigation map 4±, and when the user presses a display item data option for 44 days, the display module 25 can also The detailed data such as the stereoscopic data 、, the group (for example, the number of floors in the building), and the floor facilities in the silk object are presented to the user for browsing. In steps 33 to 34, the transparency module 24 determines the stereoscopic image located in the foreground. Whether the object map is at least partially reorganized with the road information of the current location 42 of the user on the navigation map 4. If yes, the three-dimensional object map is transparent; otherwise, the processing of step 35 is directly performed. The perspective view 41 of the building having a triangular pyramid in FIG. 4 is very close to the current position 42 of the user, and is relatively located in the foreground portion, which may obscure the road information such as the road name of the current location 42 of the user, 200926059 At this time, the transparency module 24 transparently processes the perspective 3 of the building with a triangular pyramid to complete the road information. 1 In step 35, the display module The navigation map 4 that has been integrated and has been transparently processed is displayed to the user. In summary, the navigation map 4 can be truly stereoscopically made by the present invention, so that it is no longer limited to planar data. And using transparent processing technology, so that important road information is not obscured by the three-dimensional object map, and the display is true; the object of the present invention can be achieved only by the above, only for the present invention. The present invention is not limited to the scope of the invention, and the simple equivalent changes and modifications made in the scope of the invention and the description of the invention are still within the scope of the invention.
