JP4062270B2 - Integrated display program for location objects in map content - Google Patents

Description

  The present invention relates to an integrated display program for position objects in map content.

  Conventionally, a terminal can display map information of various coordinate systems on its screen by accessing a map content server and downloading the map content from the server. Depending on the map content server, the characteristics of the content are different, so the user needs to select the map content server based on the request.

  In such a case, there is a technique in which a terminal accesses a plurality of map content servers at the same time, and superimposes received map contents on a screen (see, for example, Patent Documents 1 and 2). According to this technology, map content and location content such as an icon indicating a store location can be displayed in an overlapping manner, so that the user can view various information on a single map. .

  In addition, when a functional object indicating a predetermined range in map content such as a road and a trigger object indicating the current position of the mobile terminal are overlapped in coordinates, a technique for displaying a message included in the functional object on the screen (For example, refer to Patent Document 3). According to this technique, it is possible to determine the overlap of the image ranges of the respective objects.

Patent No. 3503397 JP 2002-140732 A JP 2003-29889 A

  Under such background technology, various position contents can be superimposed on map contents and displayed on the terminal screen. However, depending on the scale of the map content or the display screen, when displaying a plurality of position contents, the icons themselves may overlap and cannot be displayed sufficiently. This problem is particularly noticeable in the case of a small display screen such as a mobile phone.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an image overlay program that allows a user to sufficiently grasp position contents even when a plurality of position contents are displayed superimposed on map contents. .

According to the present invention, an integrated display program for position objects in map content
Means for receiving map content in a coordinate system including a plurality of map objects defining position range information;
Means for receiving a location object including location information;
Overlaying means for coordinately overlaying position objects on map content;
An integrated position object generating means for generating one integrated position object from a plurality of position objects that are coordinately overlapped with the map object of the map content;
A display image is generated from a plurality of position objects, and the display image is made to function as display image generation means for including the display image in the integrated position object.

  According to another embodiment of the integrated display program of the present invention, it is also preferable to function so as to activate a process of displaying a display image when an integrated position object is designated.

  Furthermore, according to another embodiment of the integrated display program of the present invention, the position object updates the position in time, and when the map object is designated, the overlay means and the integrated position object generation It is also preferable that the means and the display image generation means function so that the process of displaying the display image is activated.

  Furthermore, according to another embodiment of the integrated display program of the present invention, the map object includes map display condition information, the position object includes position display condition information, and the integrated position object generation means includes a position in the map display condition information. It is also preferable to integrate the position objects only when the display condition information is applicable.

  Further, according to the integrated display program of the present invention, the map object can specify a container attribute, and the integrated position object generating means only combines the position of the position object that is coordinately overlapped with the map object having the container attribute. It is also preferable to create an object.

  Furthermore, according to the integrated display program of the present invention, it is also preferable that the display image generating means generates a display image based on attribute information included in the position object.

  According to the integrated display program of the present invention, even when a plurality of position contents are displayed superimposed on the map contents, the user can sufficiently grasp the position contents.

  In addition, since the position objects can be integrated even if the position objects move in time, it becomes easier for the user to understand the current position of the position object.

  Furthermore, since it can be determined from the display condition information that the map object and the position object are to be integrated, objects that are clearly not suitable for display are not integrated. Further, since the map object can specify the container attribute, there is no wasteful process of integrating all the map objects.

  Furthermore, since the display screen information of the integrated position object is displayed based on the attribute information of the position object, the user can fully understand the position of the position object.

  Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system configuration diagram according to the present invention.

  According to FIG. 1, a terminal 1, a map content server 2, and a location content server 3 are connected via the Internet 5. The map content server 2 transmits map content at a desired position and in a desired coordinate system in response to a request from the terminal 1. The location content server 3 transmits location content such as a store in response to a request from the terminal 1. Further, the location content integration server 4 is connected to the Internet 5. The location content integration server 4 accumulates location objects that have already been integrated.

  FIG. 2 is a sequence diagram for superimposing the map content and the position object.

  The map content is map information in a coordinate system and includes a plurality of map objects that define position range information. The map content generally includes road map information, and includes a map object such as a building name. A position range is designated for such a map object. For example, according to FIG. 2, the range of the hatched portion of “○ × building” is designated. The range may be specified by the latitude and longitude and the radius thereof, or may be specified by the latitude and longitude of each corner.

The following source code is an example of a map object of map content. Source information of image information including these objects can be easily created by extending a graphics format such as SVG established by W3C.
<svg>
<!-Block shape->
<polyline points = “・ ・ ・ ・ ・ ・” />
<!-○ × Bill outline figure (polygon figure)->
<polygon points = “0,0 100,0 100,100 0,100 0,0”
POI = ”area” graphicProcessing = ”container” />
</ svg>

  According to this source code, the figure of the block of the map is defined by “polyline points”, and the outline figure indicating the range of the building is defined by “polygon points”. Furthermore, in the same contour graphic, a graphic attribute (container attribute) indicating that the object has the concept of a “container” including other geometrically included graphics, graphicProcessing = ” container ”is assigned.

  The position object includes position information and displayed icons or text characters. For example, the icons “B1 cafe ■”, “1F drag A”, “1F ◎◎ bookstore”, “2F ◆ Δ dentistry”, and “3FOO design” have respective position information. For such a position object, for example, a desired position object is searched, and the position in the real space is specified by overlapping the position object on the map content.

  An example of location object source code is shown below. Each position object may exist independently.

Drag A
<svg>
<use x = "30" y = "70" POI = "point" xlink: href = "# icon1">
<!-Location information figure->
<poi: prop floor = "1F"/>
<poi: prop name = "Drag A"/>
</ use>
</ svg>

<poi: prop name = "XX design"/>
</ use>
</ svg>

<poi: prop name = "◆ △ dental"/>
</ usr>
</ svg>

<poi: prop name = "◎◎ bookstore"/>
</ use>
</ svg>

<svg>
<use x = "60" y = "20" POI = "point" xlink: href = "# icon5">

</ svg>

(S21) It is a display diagram in which the map content and the position object are superimposed. At this time, the position object icon and text characters are displayed at the respective positions on the map object “XX building” of the map content. However, depending on the scale of the map content or the display screen, when trying to display a plurality of position objects, the icons themselves may overlap and cannot be displayed sufficiently.

(S22) According to the diagram of S21, the client can grasp that the contour graphic indicating the position range of the map object “○ × Bill” has a container attribute. Furthermore, it can be understood that the position object is included in the contour figure. This determination can be made by the client based on whether or not the “x, y coordinate value” of the position object is included in the range of “polygon points” of the map object “XX Building”. At this time, according to the present invention, the client generates one integrated position object instead of the plurality of position objects. The integrated position object may be a graphic object that visually indicates that a plurality of position objects are included therein. Since the generated object does not flow through the network in particular, it is not necessary to generate it as an SVG source, and it may be generated in the form of an internal data structure. Here, an example of the source code when an integrated position object is generated as SVG is shown.
<svg>
<!-Integrated position object (polygon figure)->
<a xlink: href = ”(information of position object included (S23 or S24)
Link to display) ”>
<polygon points = "0,0 100,0 100,100 0,100 0,0"
style = "stroke: none; fill: # ff0000;"/>
</a>
</ svg>

(S23) is an example of a display image included in the integrated position object. The integrated position object has a link for displaying information of the position object contained therein. When the map content is displayed, only the integrated position object is displayed, but when the user instructs the link given to the integrated position object, the information of the position object information included is displayed. The process for displaying the display image is activated. According to this example, it is represented three-dimensionally according to the attribute specified in the position object, for example, the floor “floor” where each store is located. The three-dimensional display here is not realized as SVG, and can be displayed by various methods depending on the application.

  The source code in which the integrated position object of S23 is described in SVG is shown below. A plurality of position objects are integrated after defining the three-dimensional shape of the building.

  FIG. 3 is a sequence diagram of a program in the present invention.

(S31) The map content server is accessed to receive coordinate system map content including a plurality of map objects that define the position range information.
(S32) The location content server is accessed and a location object including location information is received.
(S33) The position object is coordinately superimposed on the map content.
(S34) One integrated position object is generated from a plurality of position objects that are coordinately overlapped with the map object of the map content.
(S35) A display image is generated from a plurality of position objects, and the display image is included in the integrated position object.

  At this time, the position object may update the position in time by, for example, a client pull method. For example, the position object may indicate the position of the moving body. At this time, when a map object is instructed, the processing of S31 to S35 described above is caused to function, and the processing for displaying the display image is activated. Thereby, the position object currently existing in the range of the integrated position object is displayed on the display image.

  The map object preferably includes map display condition information, and the position object preferably includes position display condition information. For example, if there is an intention to display only a specific object in the map content itself, displaying a position object not related to the object only makes the display complicated for the convenience of the user. . On the other hand, it is also not preferable to display the position object so as to overlap the map content which is not related at all. Therefore, it is extremely effective to configure so that the position objects are integrated only when the position display condition information corresponds to the map display condition information.

  FIG. 4 is a functional configuration diagram of a program in the present invention.

  According to the program in FIG. 4, a program that causes the terminal 1 to function as the map content receiving unit 10, the position object receiving unit 11, the content superimposing unit 12, the position content integrating unit 13, and the display image generating unit 14. include.

  The map content receiving unit 10 accesses the map content server 2 and receives the map content desired by the user. The position object receiving unit 11 accesses the position content server 3 and receives a position object desired by the user. The content superimposing unit 12 superimposes the position object on the map content in terms of coordinates. The position content integration unit 13 generates one integrated position object from a plurality of position objects that are coordinately overlapped with the map object of the map content. At this time, the position objects are integrated only when the position display condition information included in the position object corresponds to the map display condition information included in the map object. The display image generation unit 14 generates a display image for displaying the corresponding position object. At this time, a display image is generated based on the attribute information of the position object.

  It is also preferable that the location content integration server 4 be configured to execute such a program according to the present invention. The position content integration server 4 can generate and store an integrated position object from the map content acquired from the map content server 2 and the position object acquired from the position content server 3. Thereby, the terminal 1 can acquire map content from the map content server 2, acquire an integrated position object from the position content integration server 4, and display it. Thereby, the terminal 1 can acquire the same effect as this invention, without providing the program by this invention.

  According to the above-described various embodiments of the present invention, various changes, modifications, and omissions in the technical idea and scope of the present invention can be easily made by those skilled in the art. The above description is merely an example, and is not intended to be restrictive. The invention is limited only as defined in the following claims and the equivalents thereto.
