According to the development of 3D printer the need for 3D scanning technology becomes one of the most rapid increasing parts among industries. In order to obtain 3D surface curvature of a back, an efficient approach using lattice pattern is presented. The surface curvature can be obtained from the distorted block edges projected with the black and white lattice pattern. This method uses the block patterns like chess plate in order to obtain surface curvature of a back efficiently. The block pattern provides robust result and uniform resolutions to vertical and horizontal curvature comparing to slit line pattern. The precision of this method was calculated by the experiment to a sphere model and the reconstruction result of a back was presented.
