Although the three-dimensional (3D) reconstruction result obtained by structure from motion and multi-view stereo from an image can visually confirm whether 3D reconstruction is achieved, it is not possible to scale the obtained 3D reconstruction result. Therefore, we verify whether the 3D reconstruction can be scaled based on the size of the two-dimensional (2D) code by simultaneously performing a 3D reconstruction of its target and its code whose size is known. Experimental results show that the scaled 3D reconstruction is highly accurate according to the size of the reconstructed 2D code.
