Abstract
The patent relates to a geographic information system apparatus, and specifically provides a three-dimensional geographic information system based on the mobile Internet. The three-dimensional geographic information system based on the mobile Internet is characterized in that a cellphone terminal, a flat compute, a personal computer are connected with the mobile Internet; the mobile Internet is connected with a cloud server; the cloud server is connected with a basic map data server and a three-dimensional model data server respectively. According to the three-dimensional geographic information system, map vector data and three-dimensional data of middle and small cities can be updated rapidly, visibility is improved, and a three-dimensional terrain and architecture features consistent with actual fields are provided.
Description
Technical field
This patent relates to the GIS-Geographic Information System device, is specially a kind of based on mobile Internet three-dimensional geographic information system.
Background technology
Traditional two-dimentional electronic chart service, carrying out two-dimensional map by simple point, line, surface figure expresses and displaying, the electronic chart services such as planning of general map view, point of interest inquiry, road can be provided, its data model is simple, the data storage is little, but the amount of information deficiency is directly perceived inadequately.Emulation three-dimensional geographic information system realizes the simulation of city true environment by technological means such as three-dimensional modeling, texture mapping.The cost of manufacture of early stage three-dimensional data is big, the cycle is long, data volume is big, and along with the appearance of various advanced persons' data acquisition means, the content of geographic information data is enriched constantly, and cost reduces, the cycle shortens.Simultaneously along with mobile product is popularized, PDA, Pocket PC have progressed into main product, various aspects of performance has had bigger lifting, therefore people have also had higher requirement to performance and function based on the application system of mobile device, and there is following problem in the product of present stage: long time of Data Update cycle needs is vector data and three-dimensional data particularly, and is especially longer for small and medium-sized cities, update cycle.Intuitive is poor: do not have the data reference, more do not have and consistent on the spot dimensional topography and construction characteristic.Overseas enterprise controls: core technology exists the hidden danger of national security and information security from abroad.
Summary of the invention
This patent provides a kind of based on mobile Internet three-dimensional geographic information system at above technical problem, to realize upgrading small and medium-sized cities map vector data and three-dimensional data fast; Improving intuitive provides and consistent on the spot dimensional topography and construction characteristic.
Based on mobile Internet three-dimensional geographic information system, formed by mobile phone terminal, panel computer, PC, mobile internet, Cloud Server, mobile phone terminal, panel computer, PC connect mobile internet, and mobile internet connects Cloud Server.Cloud Server connects basic map data server, three-dimensional modeling data server respectively.
Mobile internet provides data message and location confirmation information to mobile phone terminal, panel computer, PC, geographic model information is played up in Cloud Server recording processing user request information, processing, Cloud Server is noted whole geodata, in time provide geographic information services to user terminal-mobile phone terminal, panel computer, PC, simultaneously according to the stored geodata of the information updating correction of user terminal.The advantage of this patent is embodied in: upgrade small and medium-sized cities map vector data and three-dimensional data fast; Improving intuitive provides and consistent on the spot dimensional topography and construction characteristic.

Embodiment
Below in conjunction with specific embodiment and Figure of description this patent is described further.
Based on mobile Internet three-dimensional geographic information system, formed by mobile phone terminal, panel computer, PC, mobile internet, Cloud Server, mobile phone terminal, panel computer, PC connect mobile internet, and mobile internet connects Cloud Server.Cloud Server connects basic map data server, three-dimensional modeling data server respectively.Mobile internet provides data message and location confirmation information to mobile phone terminal, panel computer, PC, geographic model information is played up in Cloud Server recording processing user request information, processing, Cloud Server is noted whole geodata, in time provide geographic information services to user terminal-mobile phone terminal, panel computer, PC, simultaneously according to the stored geodata of the information updating correction of user terminal.Because the bitmap size of 3D model limits, may reduce the rendering effect of 3d model, influence precision.Must organize data according to certain data format.To different three-dimensional map data, the figure layer that is respectively different is played up processing respectively.The small-scale scene can be used as one and handles in data are handled, when the scene data scale increased, this way was obviously just not too suitable, need make piecemeal to contextual data and handle.The object of modeling: common building: residential building, common buildings such as house owed by a citizen.Sign building: landmark buildings such as mansion, office building, condo, market, school, hospital, gymnasium.Historical building thing: historical buildings such as ancient building, temple, tower, monastery.Communal facility: communal facilitys such as bridge, tube gateway, overline bridge, parking lot, public transport/subway gateway, gas station, greenery patches, fence/enclosure wall.The building modeling mainly is to use how much polygon modelings, transfers polygon (polygon) again to later on to building structure and profile, and all architectural object overall structures are with reference to satellite mapping and gather photo, and building detail will show abundant.In strict accordance with the photo modeling, reducing degree 90%.The threedimensional model of making can be at user's needs output threedimensional model and 2 d plane picture.The real-time visual of three-dimensional scenic is actually according to viewpoint parameter and application demand determines that the one or more sub-scene of which grade model of which level draws as current visible scene.For the render speed of accelerating three-dimensional object model in the hope of reaching the requirement of real-time demonstration, can be by rejecting the object of unnecessary demonstration effectively, reduce the load of graph rendering streamline, thereby improve the visual speed of three-dimensional scenic, accelerated method commonly used has the what comes into a driver's type to subtract.The rejecting of what comes into a driver's body is also referred to as the what comes into a driver's type and cuts the restriction of considering human visual angle size, and when observing a scene, the object outside the human eye angular field of view is invisible; In other words, if can be before scene drawing, can correct demonstration result not had any impact even the scene that can't see partly rejected and do not shown also.Therefore whether what comes into a driver's body rejecting technology is to realize the object or the scene that are positioned at outside the what comes into a driver's body are got rid of outside drawing process with what comes into a driver's body existence common factor by the border of judgment object or scene.In actual cutting process, the three-dimensional data organizational form of hierarchical block can improve scene cutting speed effectively, realizes showing in real time fast of scene.Because data hierarchy is conducive to extract the user's interest data, filter out useless figure layer; And by deblocking mechanism, just can directly reject the data block that is positioned at beyond the Crop Area at the cutting pretreatment stage, the data block that will be positioned at the Crop Area is simultaneously returned as part cutting result, only needs the data that intersect those and Crop Area are carried out the cutting processing of model then.
