Description

Apparatus and Method for Editing Map Data in 3D Map Service

The present invention relates to a 3D map service, and more particularly, to an apparatus and method for editing map data in a 3D map service.

In general, the 3D map service provides a map service that is more similar to an actual building by representing the buildings 110 to 140 in a three-dimensional three-dimensional representation in the map data 100 as shown in FIG. 1.

Since the conventional 3D map service is merely a 3D representation of a building, there is a demand for a method of expressing changes in how a building reacts to light according to night, day, or weather in order to feel more realistic. .

In order to express how the building reacts to light according to the night and day or the weather, 20 vertex information is required for each vertex of the remaining five faces except for the surface contacting the ground.

As described above, in the conventional 3D map service, the number of information required for contrast processing for a building is large, and there is a problem in that it takes a long time to perform the contrast processing because the contrast must be processed using a lot of information.

Therefore, there is an urgent need for a method of expressing contrast more easily in a 3D map service.

In addition, in general, in the 3D map service, a texture suitable for the shape of 3D map data is mapped and displayed on the screen through a procedure as illustrated in FIG. 2.

Referring to FIG. 2, the conventional texture processing apparatus produces a texture image (S210) and converts the produced texture image into a resource file according to a format rule (S220). Then, the conventional texture processing apparatus reads the resource file mapped to the shape of the 3D map data in the display engine (S230), and finally displays the resource file read on the 3D map display screen (S240).

In the conventional texture processing method, a manufacturer changes and modifies a texture image several times in order to produce an optimal texture image. That is, the conventional texture processing method has a problem in that a texture processing process as shown in FIG. 2 must be performed every time in order to display an optimal texture image desired by a manufacturer.

Therefore, there is a demand for a texture editing method to solve the conventional problem of having to go through a plurality of modification and modification procedures each time the texture image is changed.

In addition, 3D map service generally expresses the building's shape as modeling data in the same way as the actual building. The modeling data is data created by a designer in the same way as a real building using a 3D modeling tool. That is, the 3D map service reads the modeling data in a prescribed format and expresses the shape of the building in 3D.

However, in the conventional three-dimensional map service, the modeling data is produced in three-dimensional space, so the actual location of the building, the angle of the building based on true north, the size of the building, etc. are expressed, and thus do not exactly match the actual building. There is this. In addition, in the conventional 3D map service, since many buildings exist in nature, when the modeling data and the actual building do not match, there is a problem that a lot of manpower and time are consumed in manually editing all the modeling data.
