DRONE STEREO CAMERA 3D MODELING SYSTEM USING AN IMAGE

摘要

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.
