PURPOSE: A system and a method for obtaining photographing position information of indoor images are provided to accurately obtain a photographing position and a photographing posture value of a panorama image at low costs by obtaining contour lines of terrain features, drawings of a building, and an ashlar line of an interior plane and applying a concurrence algorithm. CONSTITUTION: A system(100) for obtaining photographing position information of indoor images comprises a camera(110), a 3D scanner(120), a gradient sensor(130), and a position value calculation device(140). The camera photographs the interior of a building as a panorama images. The 3D scanner is connected to the camera, thereby scanning the interior of the building at a photographing position of the camera. The 3D scanner obtains 3D data of an ashlar line of the interior of the building. The gradient sensor is connected to the camera, thereby obtaining a gradient value by measuring gradient at the photographing position of the camera. The position value calculating device collects the 3D data and the gradient value, thereby generating an interior ashlar line data per each photographing position of the camera. The position value calculating device obtains a coordinate value of the photographing position of the panorama image by using the measurement data of the interior of the building and the generated interior ashlar line data.
