SYSTEM AND METHOD FOR ADVANCED 3D VISUALIZATION FOR MOBILE NAVIGATION UNITS

摘要

It includes position calculation section that system, which provides three-dimensional visible navigator's mobile unit, the instantaneous position viewpoint of the mobile unit, control unit determines viewing frustum from above-mentioned instantaneous position, scene graph management device, which obtains geographical relevant object data viewing frustum at least one sea corrosion gap database and generates scene figure, carrys out tissue geographic object data, and the real time monitoring of scene figure is graphically presented in which to scene figure renderer. Described with enhancing, for mixing the image of different resolution, reduces the movement for sporting mobile unit relative to geographic(al) object in the scene figure. The access of information allows the data of on-demand to load based on viewing frustum and allows the navigation system dynamically load about geographic object data when data structure is used to store and run, and on demand, is only visible object to user.
