1. The technical field to which the invention relates.

The present invention relates to a method for displaying multi-level text data on a three-dimensional map where the text data, such as names of areas or buildings, simultaneously displayed on the display panel when displaying three-dimensional map by converting the map data with two-dimensional coordinates into map data with three-dimensional coordinates by the perspective projection. More specifically the present invention relates to a method for displaying multi-level text data on a three-dimensional map, which determines the distance from the viewpoint is displayed on the display panel volumetric map to the nodes, where will be displayed the text data, and then in accordance with these certain distances the text data with different levels of density are displayed on the panel display.

2. The level of technology

When the display panel displays a two-dimensional map, it simultaneously displays the text data, such as names of key areas or buildings, so that the user can correctly determine the two-dimensional map of a place, building, etc.

However, if on a two-dimensional map shows all the numerous text data, the density of the text data is very high the and, and therefore, the text data is displayed with overlapping. Thus, it is difficult to correctly recognize the text data.

Accordingly, when displaying such a two-dimensional map text data output by changing properly the density of the text data in accordance with the enlarged or reduced scale of a two-dimensional map so that the text data could not overlap each other. That is, when displaying a two-dimensional map on the display panel are sorting through the various levels ranging from the top level, in which you choose only the basic data, and then display them randomly on the lower level, which shows all the detailed text data, and display the text data level corresponding to a reduced or enlarged scale two-dimensional map.

For example, the text data are sorted into three levels: top level, middle level and lower level. When the display panel displays a two-dimensional map in scale upper level, as shown in figa, displays text data with a low density of the upper level. When you see the part 'And' two-dimensional map shown in figa, using enlarged scale, as shown in figv, displays the text data with the average density of the medium level is I. When the displayed part of the 'In' a two-dimensional map shown in figv, using enlarged scale, as shown in figs, displays text data with high density, corresponding to the lower level. Thus, the user can properly see the text data.

Meanwhile, as the development of positional technology, much attention is paid to display on the display panels surround cards in various fields, providing map information, including the navigation system, where the current location of vehicles, such as cars, are displayed on the display panels together with two-dimensional maps and guide the movement of vehicles or on Web-sites providing map information via the Internet.

Recent performance of computers has improved, and there was a lot of expensive three-dimensional navigation systems to display volumetric maps, such as aerial flight showing on the screens of the virtual three-dimensional effects. In such a three-dimensional navigation systems together with three-dimensional map should appear numerous text data as opposed to three-dimensional applications that are designed for use in games and the like.

In the prior art, th is would be displayed on the display panel volumetric map, as shown in figa, on the display panel displays a two-dimensional map containing the text data to indicate names of buildings and areas, and to show the same effects volumetric map, displayed on a two-dimensional map to the front of the building 100 forcibly add a shadow 102. Alternatively, as shown in figv, for the manifestation of three-dimensional effects of the two-dimensional map displayed on the display panel inclined, and on the two-dimensional map shows the two-dimensional image of the building 110 and text data.

However, displaying such a dimensional maps, as presented above, is not displaying, based on the conversion map data with two-dimensional coordinates into map data with three-dimensional coordinates by the correct perspective projection, and simply represents a very simple three-dimensional effects due to the lack of techniques and a large number of calculations. Thus, in comparison with displaying a two-dimensional map may be a problem that can lead the user even more confused.

In the patent application in the Republic of Korea No. 2003-32761, previously filed on behalf of the present applicant, for example, as shown in figure 3, map data with two-dimensional coordinates correctly converted into map data with three-dimensional to what rdinate by way of the perspective projection, that allows you to display on the display panel volumetric map and simultaneously display the three-dimensional map text data.

However, since in accordance with the above-mentioned prior art all text data is displayed regardless of the distances from the viewpoint to the nodes, where the displayed text data in the lower part of the display panel, that is, in places located closer to the viewpoint, the text data is displayed by a sparse image, and in the upper part of the display panel, that is, in places located far from the viewpoint, as shown in figure 3, appear tightly with overlays. Accordingly, there arises a problem that does not allow the user to parse the text data.

DETAILED description of the INVENTION

Below is described how to display layered text data on a three-dimensional map in accordance with the present invention with reference to the accompanying drawings, particularly figure 4-7.

Figure 4 presents a block diagram depicting the configuration of a navigation system that uses the method of multilevel display text data on a three-dimensional map in accordance with the present invention. As shown on the line is e, the navigation system includes a GPS receiver (Global Position System global system reconnaissance) 202 for receiving navigation messages transmitted by many GPS satellites 200; block map memory 204 for first storing map data with two-dimensional coordinates; unit input commands 206 for receiving operating commands in accordance with manipulations of a user; a control unit 208, capable of managing operations for determining the current location of the vehicle based on the navigation messages received by a GPS receiver 202 to read the map data with two-dimensional coordinates for a specific area of the block map memory 204 based on the specific location of a vehicle, in order to receive map data with three-dimensional coordinates by way of the perspective projection based on the read map data and to display the issued map data with three-dimensional coordinates together with text data in such a way as to track the trajectory of movement of the vehicle; and a control unit, a display 210 for displaying the current vehicle location and tracking together with three-dimensional map, and the texts of the mi data on the display panel 212 under the control of the control unit 208.

The GPS receiver 202 of the navigation system constructed as described above, receives navigation messages transmitted by many GPS satellites 200, and enters them into the control unit 208.

While driving the vehicle, the control unit 208 of the navigation system determines the current location of the vehicle using the navigation message from the GPS receiver 202, and reads map data with two-dimensional coordinates and text data for a specific area of the block map memory 204 given the current location of the vehicle.

Then, the control unit 208 converts the read map data with two-dimensional coordinates into map data with three-dimensional coordinates by way of the perspective projection. That is, the read map data with two-dimensional coordinates is converted into map data with three-dimensional coordinates using a viewpoint set in place, raised to a predetermined height including the current location of the vehicle that has been defined.

The converted map data with three-dimensional coordinates display on the display panel 212 via the control unit display 210.

Then the unit is driven by what I 208 converts the read text data in the text data in the three-dimensional coordinate system with the origin, a certain viewpoint, and displays the converted text data on the display panel 212. Next, the control unit monitors the movement of the vehicle, thus indicating the movement trajectory of the vehicle on the display panel 212 arrows, etc.

Here, the navigation system as an example of the navigation system fixedly installed in the vehicle. Otherwise, when such a navigation system installed in a mobile device, the capacity of the memory block map memory 204 is limited. Accordingly, in response to commands from the input block commands 206 may be connected to the map server to download map data with two-dimensional coordinates for a particular area, for example the whole area of Seoul, and the loaded map data can be stored in the block map memory 204 and then used.

On figa and 5B presents a flowchart illustrating a display method in accordance with the present invention. As shown in these figures, the control unit 208 sets the coordinates of the source location to use when creating a volumetric map (step 300). Here, as for the coordinates of the original location at step 300, as the coordinates of the source location mo the ut to be specified coordinates of the current location of the vehicle, some of the messages received by the GPS receiver 202, or the coordinates entered by the user through the input block commands 206.

When installing the coordinates of the original location on the stage 300 is fully completed, the control unit 208 performs the initialization process of three-dimensional environments to display map data with three-dimensional coordinates or specific models with three-dimensional coordinates on the display panel 212 (step 310). The initialization process of three-dimensional environments on stage 310 includes the following steps. Initializes the environment lighting (step 311). When initializing the lighting environment at step 311 are set viewpoint, the line of sight, the direction of the light source, the intensity of the light source, color and saturation to denote the sides of buildings in accordance with the orientation angles of the sides of buildings, etc. Then initialized depth buffers (step 312). That is initialized depth buffers to indicate distances from the point of view to locations where they will display certain objects, including rivers, bridges, buildings, and text data. Then removed the background color displayed on the display panel 212, and is set in advance to a specified color (step 313).

Upon completion of the initialization process of three-dimensional environments at stage 310, the control unit 208 performs the installation process viewpoint (step 320). the process of installing viewpoint on the stage 320 includes the following steps. First, set the position of the viewpoint (step 321). Regarding the setting of the viewpoint, for example, as a vantage point the coordinates of its location, is raised to a predetermined height within the specified coordinates of the original location. After installation, the viewpoint is set to the line of sight from the set position of a viewpoint in a three-dimensional map or model (step 322). For example, as the line of sight is set to the direction of movement of the vehicle.

Upon completion of the installation process viewpoint at step 320, the parameters for the projection for use in the projection transformation, where the map data with three-dimensional coordinates are projected onto the plane of projection (step 330).

While the control unit 208 executes the initialization process of three-dimensional environments at stage 310, the installation process viewpoint on the stage 320 and the installation process of projection parameters at step 330, the control unit loads the map data with two-dimensional coordinates of the block map memory 204 (step 340) and performs a process of three-dimensional modeling modeling loaded map data with three-dimensional coordinates into map data with three-dimensional coordinates (step 350).

The process of three-dimensional modeling on stage 350 which engages in the following steps. Text data with two-dimensional coordinates, loaded with map data with two-dimensional coordinates at step 340, extended to three-dimensional coordinates (x, y, k) (step 351). The extension to three-dimensional coordinates consists in the attribution of values of k the height of the text data, where k may vary according to where you already have a place to display text data on the upper or lower parts of buildings, or over or under buildings. Then take the three-dimensional planar objects for flat objects, such as roads, green areas, rivers and lakes, located on the three-dimensional map below (step 352). That is, two-dimensional coordinates of the planar objects are extended to three-dimensional coordinates (x, y, 0)to planar objects could be placed on the three-dimensional map at the bottom. Set the height of the nodes of the respective buildings (step 353), displays a three-dimensional building with predetermined heights (step 354), and also displays the path of the vehicle using the arrows or dotted lines (step 355).

At step 360, the control unit 208 performs the conversion process point of view. The conversion process viewpoint on stage 360 includes the following steps. The nodes map data, extended to three-dimensional coordinates in the three-dimensional process simulation, transform nodes in the map data trehmernoi coordinate system with the origin, a certain point of view, through the three-dimensional position and rotation relative to the origin (step 361). Text data with three-dimensional coordinates is converted into text data in the three-dimensional coordinate system with the origin defined by the view point (step 362). After conversion, the conversion process point of view the three-dimensional coordinates are converted into three-dimensional coordinates in the new three-dimensional coordinate system with the origin defined by the view.

At step 370, the control unit 209 performs a process of determining distances, which consists in determining distances from the point of view to locations where they will display the text data. During the process of determining the distance at step 370, because the values of Z for text data into a new three-dimensional coordinate system with the origin defined by the view, are the distances from the point of view to sites displaying text data with three-dimensional coordinates are determined by the values of Z for text data converted to text data in the three-dimensional coordinate system with the origin defined by the view, and set the flags distances for nodes display the text data according to the ranges of distances corresponding to these particular values for the OS the Z (step 371).

At step 380, the control unit 208 performs the deletion process models, consisting in the removal of unwanted models. During the removal process models deleted all models, existing three-dimensional map out the field of view (step 381), and also removes any overlapping and hidden volume side, i.e. overlapping and hidden side of the object, shown with overlay (step 382).

At step 390, the control unit 208 receives the screen coordinates on a two dimensional screen when performing projective transformation process. During the projection transformation at step 390, the corresponding nodes are converted to nodes in the coordinate system with the origin defined by the view, subject to projection transformation in the two-dimensional plane (step 391), get the coordinates of the two-dimensional projection (step 392), text data is subjected to projection transformation (step 393), and the corresponding projected coordinates are converted to screen coordinates (step 394).

At step 400, the control unit 208 performs a process of displaying on the screen that displays on the screen of the display panel 212 to screen coordinates using the control unit display 210. The process of displaying on the screen at the stage 400 includes the following steps. Display broken line of flat objects, such as roads, the green circle area, rivers and lakes (step 401). Display broken line path of movement of the vehicle (step 402). Then display the three-dimensional building (step 403). Then display the text data with different levels of density in accordance with the flags of the distances of the nodes to the corresponding text data to be displayed (step 404).

In the present invention, for example, for objects that should be displayed on the three-dimensional map defined distance, which represents the magnitude of the z-axis from the point of view 500, and then classification is performed on a range of small distances, the range of average distances and the large range of distances, as shown in Fig.6. For objects that fall in the range of small distances, displays the text data of the lower level with high density, for objects within the range of average distances are displayed textual data of the middle level with average density, and for objects falling within the range of distances that displays the text data of the upper level with a low density. Thus, the user can correctly parse the text data displayed on the display screen, as shown in Fig.7.

As described above, in accordance with the present invention advantages are that when displayed on the display panel vol the second map displays the text data with different levels of density in accordance with the distances from the point of view to locations, where will be displayed the text data that could be improved readability of the names of places on a three-dimensional map, and that the density of the text data can be adjusted for the convenience of users or developers.

SUBSTANCE: generation employs a method of searching for exact matching on all three channels RGB and optimised colouring in case of insufficient exact matching of colours. The data base of initial images is collated and the images are then sorted and a static and a dynamic coordinate grid are then superimposed onto the target image, where the image is placed in the cells of the grid. A tile-image is generated and then converted to digital form with possibility of transmission by electronic devices and printing on a printer. The initial image is broken into elements of fixed dimensions with possibility of changing dimensions of the cells depending on dimensions of the initial images. The initial image is selected from the sum of moduli of deviation on all three colour channels RGB. The initial image is corrected such that its average value becomes equal to the average value of the colour of the tile on the target image. Each initial image is then scaled to given dimensions and inserted into the corresponding position of the created tile-image.

EFFECT: high quality of tile-images and broader functional capabilities.

FIELD: metrological equipment for navigational systems of railroad transport.

SUBSTANCE: in accordance to method, working sides of railroad track are coordinated with given stationing interval by means of measuring-computing complex mounted on moving object. Measuring-computing complex includes rover, gyroscopic indicator of Euler angles, indicators of track and width of track, controller, personal computer. To provide unity of measurements on railroad main, single three-dimensional orthogonal system of coordinates is used in special projection. Abscissa axis on the surface of Earth ellipsoid is combined with geodesic line, coinciding with main direction of railroad main. As ordinates, geometrical perpendiculars to abscissa axis are used. Coordinates system base consists of system of temporary base stations of satellite radio-navigation system. Satellite radio-navigation system stations are positioned along the railroad with 50-100km intervals for the time of movement of measuring-computing complex. Continuous synchronous recording of indications of all devices and satellite receivers of base stations is performed. Coordinate models of railroad track having no substantial distortions of angles and distances are taken as standard. For compensating systematic errors, indications of Euler angle indicator on measuring-computer complex are smoothed by sliding average filter on sliding interval, equal to length of wheel circle of moving object. Corrections for inclination of antenna are introduced to satellite coordinates of receipt of rover of measuring-computing complex. Indications of course track indicator are calibrated by means of center-affine transformations, converting to series of directional angles and scaled horizontal projections. Joint estimation of complex measurements and parameters of statistic model is performed by means of recurrent generalized method of least squares.

EFFECT: increased precision when determining standard coordinate model.
