Design And Fulfillment Of Panorama Showing System Based-on Image Stitching

Nowadays,with the development of our society and technology,there are always masses of image infomation will have to be recorded.But these single images can only provide us limited local infomation.If we use image stitching technology,we can stitch several single image into a panorama,then using a specific projecting approach to show the panorama,well then we will get a wider image,which includes different perspectives of our view.The research of this project mainly includes two sides:One is contrasting the present image stitching algorithms,namely,NISwGSP that is issued in ECCV 2016 and image stitching of OpenCV,selecting the one that has better effect to stitch a panorama.Our choice of selecting NISwGSP is because it uses a more advanced technology,and its panorama has a more natural effect.This is mainly because it divides an image into meshes,and in the image overlapping part,it uses localized homography alignment,and the non-overlapping part,it uses global homography alignment.Meanwhile,it uses a special approach to rotating image to get a more natural effect.The stitching algorithm of OpenCV forms the traditional stitching method,namely,global homography alignment,cylindrical or sp herical projection,bundle adjustment and blending,since Autostitch had been created.Another is after stitching a panorama,using OpenGL to draw a sphere and projecting the panorama to the spere surface to get a good showing effect.The method to drawing a sphere is,firstly,from north pole to south pole,each time rotating a set angle?Secondly start from east,each time rotating a set angle,eventually,along a latitudinal circle to the start point.Using a method that each time it will draw a triangle,two times draw a mesh.Through the tests we find that the stitching algorithm of OpenCV has an obvious advantage in blending effect and it will stitch a better panorama than NISwGSP algorithm.In terms of projection,we get a favorable three-dimensional feelings in showing effect through using spherical projection technology.
