In recent years, 3D display technique is one of the emerging technology and gradually becomes accessible to a broader audience. However, because of the traditional 3D reconstruction method is limited by the number of the feature found in the image, the resolution of the generated 3D model is not high enough for 3D display. A new system is purposed, in which we consider the vertical and horizontal disparity between images, and the optical flow is used to replace the feature matching segment, so that more points can be pushed into the reconstruction process for improving the resolution of the models. Experimental results prove that the resolution of the models can be enhanced effectively. The details of the model are preserved, and the holes in the weak texture region are successfully filled.
