The Research And Development Of Walk-in Panorama System

With the rapid development of computer technology, multimedia increasingly being used to all aspects of life and the type of media is becaming more and more,the effect of the performance is also becaming more and more.The performance of traditional methods are increasingly unable to meet most of the clients requirements for the display mode.The performance of the traditional way includes plane image, vedio and three-dimensional modeling. Static image can only provide images of the scene at an angle.Even when shooting using the wide-angle lens,it is difficult to achieve an effective and comprehensive full performance of the scene.Shooting video can allow users to have a complete understanding of the scence,but still be limited in viewing angle.Users watching angle depends on the photographer's shooting mode,it's not free and users can't interact.Three-dimensional modeling approach can solve both static images and dynamic video problems but it's costly and authenticity does not always satisfactory.Therefore,we need real,comprehensive,intuitive performance of a scence,to go into the function with a 360-degree panorama rendering technique is undoubtedly the best choice.This paper mainly studies have went to the Panorama function of system's analysis,design and implementation.The entire system includes 360-degree spherical panorama generator software,walk-in scenario generator software,voideo scence generator software,and the roaming sub-softwate.The organizational form of the whole system is:from 360-degree spherical panorama generator software to generate a certain point in sight roaming the whole scene,you can achieve the level of 360 degrees,vertical 180 degrees panoramic view.The walk-in scenario generator software generates walk-in roaming scenarios,in order to achieve the depth of a scene,or to connect two spherical roaming scenarios,so that over-produce better results.Video scene generator software can also be generated walk-in roaming scenarios,so that we have choice of the type of the walk-in scence.Roaming software is the role of the child in all the above sub-roaming scenarios generated by the software organic link and display to the computer.Meanwhile,roaming software alse includes interface and complete interactive features,it is front of the whole system.Walk-in roaming'effects used two methods to achieve:one is tour into picture arithmetic,it can used only one photograph create realistic three-dimensional effects.Other one is video-based algorithms,it can extract frames in the videos and using the freams as texture mapping to a plane as a set of nodes in order to produce to the effect of walk-in.
