The present invention relates to a system for acquiring information necessary for 3D modeling of a geographic feature and, more specifically, to a 3D modeling system using an image captured by a stereo camera of a drone, in which first and second cameras provided in a drone unit acquire photographing information by photographing a front surface for measuring a vertical length of a geographic feature, an upper surface for measuring a horizontal length thereof, and a side surface for measuring a height thereof, such that a distance from the front surface, a distance from the upper surface, and a distance from the side surface are equal to one another by position verification sensors and first and second position determination sensors, and the vertical length, the horizontal length, and the height of the geographic feature are calculated according to a use number of preset content by calling the photographing information so as to match a limit point normalized in a screen display unit, thereby acquiring information about the geographic feature necessary for 3D modeling. To this end, according to the present invention, the 3D modeling system using an image captured by a stereo camera of a drone comprises: position verification sensors which are installed on a front surface, a side surface, and an upper surface of a geographic feature having a rectangular shape, and irradiate laser beams having straightness; a photographing means which acquires two-dimensional photographing information transmittable through a wireless communication network by respectively photographing the front surface, the side surface, and the upper surface of the geographic feature in the sky while maintaining an equal distance through the position verification sensors; and a terminal unit which receives the two-dimensional photographing information, displays the received two-dimensional photographing information on a screen, and allows a 3D modeling operation to be performed by respectively calculating the front surface, the side surface, and the upper surface of the geographic feature through the displayed two-dimensional photographing information.

    본 발명은 지형지물의 3차원 모델링에 필요한 정보를 획득하기 위한 시스템에 관한 것으로, 더욱 상세하게는 드론부에 구비된 제1 및 제2카메라가 지형지물의 세로길이를 측정하기 위한 전면, 가로길이를 측정하기 위한 상면 및 높이를 측정하기 위한 측면을 각각 위치확인센서와 제1 및 제2위치판별센서에 의해 동일한 이격 거리를 갖도록 촬영하여 촬영정보를 획득하고, 그 촬영정보를 화면표시부에 규격화된 리미트 포인트와 일치하게 불러내어 미리 설정된 컨텐츠의 사용 개수에 따라 지형지물의 세로길이, 가로길이 및 높이를 연산하도록 함으로써, 3차원 모델링에 필요한 지형지물의 정보를 획득할 수 있는 드론의 스테레오 카메라가 촬영한 이미지를 이용한 3차원 모델링 시스템에 관한 것이다. 이를 위해 본 발명에 따른 드론의 스테레오 카메라가 촬영한 이미지를 이용한 3차원 모델링 시스템은 직육면체 형상을 갖는 지형지물의 전면, 측면 및 상면에 각각 설치되되 직진성을 갖는 레이저를 조사하는 위치확인센서와, 상공에서 상기 위치확인센서를 통해 동일한 거리를 두고 각각 촬영하여 무선통신망에 의해 전송가능한 2차원적인 촬영정보를 획득하는 촬영수단 및 상기 촬영정보를 수신하여 화면으로 표시하되 표시된 상기 촬영정보를 통해 상기 지형지물의 세로길이, 가로길이, 높이를 각각 연산하여 상기 지형지물의 3차원 모델링 작업이 이루질 수 있도록 하는 단말부를 포함한다.
