Abstract
An image forming system for constructing a whole large image of an object is provided. The image forming system includes an interface configured to sequentially acquire images of partial areas of the object obtained by a camera, wherein two adjacent images of the partial areas include overlap portions, wherein the sequential images correspond to a three dimensional (3D) surface of the object, wherein the geometrical information (geometrical parameters) of the object is provided, wherein an initial pose of the camera is provided. The system further includes a memory to store computer-executable programs including a pose estimation method and a stitching method, and an image stitching processor configured to perform steps of estimating camera poses with respect to the sequential images by the robust camera pose estimation method which imposes low-rankness and joint sparsity of relative pose matrices, projecting the sequential images into a 3D surface based on the camera pose estimations, and constructing a two-dimensional (2D) image of the object by interpolating projected surface images; outputting the constructed 2D image via the interface.
