Research On The Application Of Virtual Reality Technology In Wutai Mountain Panoramic Tourism

With the increasing popularity of panoramic roaming,panoramic image stitching has become the focus of research.The effect of image stitching directly affects the real feeling of panoramic roaming.The ordinary camera used in the traditional image mosaic technology needs to take multiple photos with overlapping areas due to the limitation of the lens angle range.It is difficult to take photos and the image mosaic is complex.The fisheye camera is widely used because of its short focal length and ultra wide angle.However,the distortion of fisheye image and the stereo effect of panorama increase the difficulty of image mosaic.In this paper,the fisheye images of Wutai Mountain scenic spots are collected,the image mosaic technology is studied,the best suture method is improved,and the mosaic effect of panorama is optimized;The collision detection algorithm is improved to improve the efficiency and accuracy of collision detection in mobile platform roaming system;The design method and implementation of scenic spot roaming system are studied.The main research contents and achievements of this paper are as follows:(1)Aiming at the distortion of fisheye image,the image is corrected,and the splice distortion caused by collecting images from different directions is solved by using spherical projection and planar expansion of inverse mapping.Aiming at the obvious problem of image stitching seam in the process of image stitching,the best suture method is improved.The improved stitching seam transition is smooth and the stitching seam is eliminated.(2)Aiming at the problems of small memory and slow running speed on mobile platform,LOD technology is used to establish a multi-level detail model to reduce the rendering time of the system;A collision detection algorithm combining OBB bounding box,LOD technology and particle swarm optimization method is proposed,which improves the efficiency and accuracy of collision detection on mobile platform.(3)Design and implement the Wutai Mountain scenic spot roaming system,design two modes and multiple functions,ensure the practicability,interest and interaction of the system,display the history and culture of Wutai Mountain in an all-round way,and increase the user’s sense of experience.
