Abstract

본 발명은 위성영상사진이나 항공사진 위에 포함되어 있는 지명이나 지상물의 위치와 특징을 데이터베이스에 등록하여 검색하는 방법에 관한 것으로서, 인공위성에서 활영한 위성영상에 대한 지명과 지상물을 표시하여 사진의 독해력을 높힐수 있다. 입수된 위성영상사진과 항공사진으로부터 촬영한 지역의 크기와 영상칼러 정보를 이용하여 수집 과정에서 발생된 왜곡 된 현상을 처리한 후 각 사진 위에 지명과 지상물을 심볼화하여 오버레이하여 디스플레이 할 수 있다. 이런 장치는 기존의 처리된 영상을 디스플레이 했을 때 그 영상을 설명하는 자세한 지명과 지상물이 표시되지 않아 그 지역을 잘 알고 있는 몇 몇 전문가들이 특수한 목적으로만 이용할 수 있는 분야에서 벗어나 일반 사람도 이용할 수 있도록 그 활용 범위를 확장할 수 있다. 본 발명에서는 우선 영상 사진을 보고 지명이나 자상물을 등록하기 위해 해당 지역의 지명이 데이터베이스로 등록할 수 있어야 하고 해당 위치에 지상물의 종류에 따라 비트맵으로 작성된 여러 기호 종류 리스트를 미리 작성하여야 한다. 그동안 고정밀 상업위성의 제작 기술의 발달로 위성영상사진의 해상도가 점점 높아지고 있기 때문에 해상도가 1~3미터인 영상을 쉽게 입수할 수 있다. 해상도가 높은 사진의 장점은 확대를 하여도 영상의 입자가 깨지지 않아 육안으로도 지형 및 지상물의 확인이 가능한 것이다.The present invention relates to a method of registering and searching a location or feature of a place name or ground object contained in a satellite image or aerial photograph in a database. Can increase. After processing the distorted phenomena generated during the collection process using the acquired satellite imagery and the size and image color information of the area taken from the aerial photo, symbolic names and ground objects can be displayed on each photo for overlay. . These devices, when displayed on an existing processed image, do not display detailed names and ground descriptions that describe the image so that some professionals who are familiar with the area can use it for general purposes only. Its scope can be extended to help. In the present invention, first, in order to view a video photograph and register a place name or statuary object, a place name of a corresponding region should be able to be registered in a database, and a list of various symbol types prepared as bitmaps according to the type of ground material at the corresponding location should be prepared in advance. Since the resolution of satellite imagery is increasing due to the development of high-precision commercial satellite production technology, it is easy to obtain images with a resolution of 1 to 3 meters. The advantage of high resolution pictures is that the particles of the image are not broken even when enlarged, so that the terrain and ground can be checked with the naked eye.
