Abstract
The invention discloses a vector modeling and display and interaction method of an indoor map at a mobile terminal. Through the modeling processing technology of indoor map data, the high-definition three-dimensional display effect of an indoor map facility is realized at the mobile terminal, and the attribute edition and management of the facility can be realized. In an aspect of operation, the indoor map can be smoothly and steplessly zoomed and dragged, and can be freely switched into three-dimensional map and two-dimensional map modes, and the 360-degree viewing angle conversion in the three-dimensional map mode can be realized. The accurate mutual conversion between a geographic coordinate system and an indoor map coordinate is realized in an aspect of docking to an outdoor map. The method can be widely used for display and interaction of the indoor map at the mobile terminal.
Description
Technical field
The invention belongs to space technology message area, relate to Vector Modeling and displaying and the exchange method of a kind of indoor map at mobile terminal.
Background technology
The rise of mobile Internet, makes people can inquire about easily outdoor map.But along with City Building is towards larger higher future development, the distribution situation of interior architecture thing and facility is understood in the hope that people are more urgent by mobile terminal, therefore also increasing to the demand of indoor map.People not only require indoor map file to facilitate attractive in appearance representing at mobile terminal better, and also requirement can be mutual with it, require the few fast response time of committed memory simultaneously, and the indoor map of therefore making adaptation mobile terminal becomes a kind of research and development focus.
Summary of the invention
The object of this invention is to provide Vector Modeling and displaying and the exchange method of a kind of indoor map at mobile terminal, by the modeling process technology to indoor map datum, not only realize the 3 D stereo display effect of indoor map facility high-resolution at mobile terminal, can also carry out attributes edit and management to facility.Can be smooth in operating aspect indoor map be carried out stepless zooming and dragged, and freely switches to three-dimensional map and two-dimensional map pattern, can also under three-dimensional map pattern, realize 360 degree visual angles and change.Aspect docking with outdoor map, realizing the accurate conversion mutually of geographic coordinate system and indoor map coordinates system.Can be widely used in indoor map in the displaying of mobile terminal and mutual.
The present invention is by the vectorized process to interior architecture object plane CAD figure, can carry out three peacekeeping two dimensions at mobile terminal easily shows, and the POI point of inside plant is edited and processed, thereby can carry out easily alternately, can be used for the Navigation and localization of indoor map at mobile terminal.
Indoor map of the present invention the Vector Modeling of mobile terminal with as follows with displaying and exchange method step:
The first step: plane CAD mapping
Second step: vector graphics geographic coordinate registration
The 3rd step: vector graphics attributes edit
The 4th step: derive the vector file with attribute data
The 5th step: mobile terminal loads vector map data and resolves
The 6th step: build three-dimensional indoor cartographic model
The 7th step: the indoor POI point coordinate data of step 7.1 gathers
Step 7.2 is changed actual geographic coordinate
The deep processing of step 7.3POI data
The 8th step: load POI data and draw
The invention has the advantages that:
1 has realized the minimization of data, conveniently represents fast at mobile terminal;
2 have realized at mobile terminal mutual to indoor map;
3 can show with two and three dimensions, realize the rotary display that indoor map 360 is spent simultaneously under Three Dimensional Interface;
4 can realize the seamless link of indoor map and outdoor coordinate system;
Brief description of the drawings:
