Research And Implementation Of Campus Three-dimensional Reality Based On Panorama

With the rapid development of virtual reality,digital image and computer technology,people have more and more demands on interactive experience.The campus real scene show is moving towards the direction of"natural,realistic,interactive and convenient".As a branch of virtual reality,the three dimensional panoramic technology is developing rapidly and gradually popular.Three dimensional panoramic is characterized by its strong interaction,real rendering,fast gradient and deep panoramic etc.With these advantages,it effectively makes up for the traditional teaching field,the map area,the virtual display is not realistic and so on.It meet the requirements of the basic interaction in the field of modern virtual display,and it has been widely concerned.The application of campus real three-dimensional display is based on virtual reality,it takes the Tianjin University of Science and Technology as the research object.It is an application software which uses the technology of three-dimensional panoramic view,and it has the function of campus display and navigation.First,we analyzed the location of Tianjin University of Science and Technology and set position information point of the school.We collect position point by camera,and use PTGui software to create a panoramic image of the various locations.After that we adjust the position of the image control point to synthetize 54 pieces of panoramas.Then we can make the campus tour through the Pano2VR software and convert the panorama roaming to the dynamic file displayed in the web page.Afterwards,we use HTML5technology to achieve the corresponding information and navigation functions of the website.At last,the application software can be used on the mobile terminal,if it is developed by Android development platform.This application has functional modules including campus overall view,the real point display,virtual roaming and campus information display.Its implementation not only meets the needs of teachers and students in school to comprehend the location information and the demand of campus resource information,but also can provide more direct and more accurate information for other users who need to know the campus information.Through the analysis and comparison of the panorama synthesis technology,we can select the most appropriate projection model.We can also realize panoramic roaming in the mobile terminal and complete the development of Android client.
