Abstract

PURPOSE: The method for displaying three-dimensional building by non-calculated algorithm is provided to cut the high cost of hardware equipments, to reduce the internet traffic by the lightness of the three-dimensional data, and to extract the more realistic data than the three-dimensional building data by non-calculated algorithm. CONSTITUTION: The method for displaying three-dimensional building by non-calculated algorithm comprises the following method. The user enters into the map service site after connecting to the internet(1). The web server(3) plays the role in the intermediary between the accessed user and the map service software using non-calculated algorithm. The internet map service software(4) makes the map out of the data stored in the DB(data base)(5) by using non-calculated algorithm, and the building is shown in the more three-dimensional data. The smaller three-dimensional map information, shown through the web server and the internet, is serviced for the user.

Description

인터넷 지도서비스에서 Non-calculated 알고리즘에 의한 건물의 입체적 3차원 표현방법{3-dimensional display of buildings in Internet map service with non-calculated algorithm}3-dimensional display of buildings in Internet map service with non-calculated algorithm

본 발명의 분야는 인터넷상에서 건물의 3차원 지리정보시스템을 제공하고자 할 때 사용되어지는 기술로 과거에는 건물의 3차원 표현을 위해 복잡한 수식에 의한 계산의 수반되어져 고가의 하드웨어 장비를 필요로 하며, 그 계산식에 의해 표현된 3차원 건물도 현실감이 떨어진다. 또한 3차원 데이터의 증가로 인터넷상에서 서비스될 경우 많은 전송망의 트래픽을 유발하고 있는 실정이다.The field of the present invention is a technology used to provide a three-dimensional geographic information system for buildings on the Internet. In the past, it requires expensive hardware equipment, which involves complex calculations for three-dimensional representation of buildings. The three-dimensional buildings represented by the formula are also less realistic. In addition, due to the increase of 3D data, when the service is performed on the Internet, it causes traffic of many transmission networks.

인터넷에서 제공되는 지도검색서비스에서 복잡한 처리과정의 결과로 얻어지는 건물의 3차원 데이터 생성과정의 생략.Omission of three-dimensional data generation of buildings resulting from complex processing in map search service provided on the Internet.

- 생략되어지는 계산에 의한 고가 하드웨어 장비의 비용절감-Cost reduction of expensive hardware equipment by eliminating calculation

- Non-calculated 알고리즘에 의한 3차원 데이터의 경량화로 인터넷트래픽 감소-Reduction of Internet traffic by lightening three-dimensional data by non-calculated algorithm

- Non-calculated 알고리즘에 위해 기존의 복잡한 계산식에 의해 얻어지는 3차원 건물데이터보다 현실감 있는 데이터 추출-Extraction of data more realistic than 3D building data obtained by existing complex calculation formula for non-calculated algorithm

도 1은 전체의 구성도1 is a configuration diagram of the whole

도 2는 Non-calculated 알고리즘2 is a non-calculated algorithm

도 3은 Non-calculated 알고리즘이 적용된 3차원 표현과 적용후 3차원 표현내용3 is a three-dimensional representation of the non-calculated algorithm and three-dimensional representation after application

도1은 사용자가 온라인 지도서비스를 받기 위해 인터넷에 접속한후 URL을 이용하여 지도서비스 사이트에 들어간다. 도1의 ③ WEB 서버는 접속된 사용자와 Non-calculated 알고리즘이 적용된 지도서비스 소프트웨어의 중계역할을 한다. 도1의 ④인터넷 지도서비스 소프트웨어는 Non-calculated 알고리즘을 이용하여 도1의 ⑤DB상에 저장된 데이터를 지도로 만들어주며 이때 건물정보는 입체감있는 3차원 정보로 표현하고 있다.Fig. 1 shows a user accessing the internet to receive an online map service and then entering a map service site using a URL. ③ WEB server of Figure 1 serves as a relay between the connected user and the map service software to which the non-calculated algorithm is applied. The ④ internet map service software of FIG. 1 maps the data stored in the ⑤DB of FIG. 1 using a non-calculated algorithm, and the building information is expressed as three-dimensional information with three-dimensional effect.

도1의 ⑥,⑦을 이용하여 이렇게 표현된 적은 용량의 3차원 지도정보를 사용자에게 제공한다.By using ⑥ and ⑦ of FIG. 1, the user can be provided with 3D map information having a small capacity.

기술한 내용을 보면 자명하듯이 인터넷 지도 서비스상에서 현실적 입체감이 살아있는 3차원 건물정보를 제공하기 위해서는 Non-calculated 알고리즘이 필요하며 이는 복잡한 계산과정을 생략시켜 고가의 하드웨어 구입의 경제적 어려움을 극복할수 있고, 표현된 데이터의 경량화를 유도하여 인터넷상의 트래픽을 감소시켜 무절제한 인터넷회선 증가비용을 절감시키며 사용자가 원하는 보다 현실감있는 시각적인 욕구를 충족시킬수 있다.As is clear from the above description, a non-calculated algorithm is required to provide three-dimensional building information with realistic three-dimensional image on the Internet map service, which can overcome the economic difficulties of expensive hardware purchase by eliminating the complicated calculation process. It can reduce the traffic on the Internet by inducing the light weight of the expressed data, thereby reducing the cost of increasing the Internet line and satisfying the more realistic visual needs of the users.
