A line scan camera-based structure from motion method for high-resolution 3D reconstruction is proposed. The imaging model of a line scan camera is discussed to characterize the relationship between the coordinates of the physical object in space and the corresponding coordinates of its image taken by the scanner. A camera calibration framework based on such a system to estimate the intrinsic parameters and a set of extrinsic parameters along with recovering 3D shape of the object are addressed in detail for high-resolution 3D reconstruction with improved efficiency. The method was applied to the 3D reconstruction of 31 statues belonging to World Cultural Heritage Ninnaji Temple in Japan. Experimental results demonstrate the merit and effectiveness of this method to high-resolution digitization of cultural heritage.
