3D Map Distribution Server Device, Client Terminal Device, and 3D Map Distribution System
First Claim
1. A three-dimensional-map distribution server device, comprising:
- a storage unit which stores a plurality of structure shape data drawn on a ground to generate a three-dimensional map image;
a server communication unit connected to a network;
a list transmitting unit which transmits through the server communication unit a list, which includes a plurality of structure shape data within a district and position information of the district or of the structures; and
a data transmitting unit which, when the server communication unit receives a transmission request for the structure shape data selected based on the position information in the list, transmits requested structure shape data in the storage unit through the server communication unit.

Abstract
A three-dimensional map distribution server device stores shape data for structures drawn on a ground to generate a three-dimensional map image, and, in the first place, transmits to a client PC a list which includes shape data for structures in a district and has position information of the district or of the structures. The client PC selects shape data required for the display based on the position information in the list, and transmits a transmission request for the selected shape data to the three-dimensional map distribution server device. When receiving the request, the three-dimensional map distribution server device responds and transmits to the client PC the requested shape data.

8. A three-dimensional-map distribution server device, comprising:
-
a storage unit which stores a plurality of point data, each of which is in correspondence with a point in a three-dimensional map image, and each of which has display information of the related point;
a server communication unit connected to a network;
a list transmitting unit which transmits through the server communication unit a list, which includes a plurality of point data within a district and position information of the district or of the points; and
a data transmitting unit which, when the server communication unit receives a transmission request for the point data selected based on the position information in the list, transmits requested point data in the storage unit through the server communication unit.

9. A client terminal device, comprising:
-
a client communication unit connected to a network;
a list receiving unit which receives a list, which includes a plurality of structure shape data within a district drawn on a ground to generate a three-dimensional map image, and has position information of the district or of structures, through the client communication unit;
a data receiving unit which transmits a transmission request for the structure shape data within a range of a predetermined distance from the eyepoint, where the structure selected based on eyepoint information to generate a three-dimensional map image and on position information in the list, through the client communication unit, and receives the requested structure shape data, through the client communication unit;
an image data generating unit which generates a three-dimensional map image data within a field of view from the eyepoint toward the ground at a angle, using the structure shape data received based on the transmission request; and
a display unit which displays a three-dimensional map image, based on the data generated by the image data generating unit. - View Dependent Claims (10, 11, 12)

13. A client terminal device, comprising:
-
a client communication unit connected to a network;
a list receiving unit which receives a list, which includes a plurality of point data, each of which is in correspondence with each of locations, within a district and drawn for display information on a ground to generate a three-dimensional map image, and has position information of the district or of points, through the client communication unit;
a data receiving unit which transmits a transmission request for the point data within a range of a predetermined distance from the eyepoint, where the point selected based on eyepoint information to generate a three-dimensional map image and on position information in the list, through the client communication unit, and receives the requested point data, through the client communication unit;
an image data generating unit which generates a three-dimensional map image data within a field of view from the eyepoint toward the ground at a angle, using the point data received based on the transmission request; and
a display unit which displays a three-dimensional map image, based on the data generated by the image data generating unit.
