Abstract: The multi-viewpoint panorama of long scenes is produced from a relatively sparse set of images captured with a camera that is moved along the scene.A novel method for producing panoramas of long scenes based on graph cuts is proposed.Source images are projected onto the picture surface.The energy function is built based on several conditions of the long scenes，and the problem of view selection is translated into the problem of minimizing energy function.The energy function is minimized using Boykov’s method.Experimental results show that the panoramas produced from this algorithm seems quite natural，and the transitions between different regions of linear perspective are more natural and seamless.

Key words: panoramas of long scenes, picture surface, energy function, graph cut
