【摘要】 在实景展示问题的研究中,全景图是虚拟现实场景显示的重要方法。结合OpenCV开源计算机视觉库,设计了曲面全景投影中的一种特殊情况,即全景图像环状柱面投影并旋转算法,主要包括基于平面图像的柱面正投影算法、图像拼接方法、基于图像截取实现图像旋转效果算法、图像拆分方法和从柱面到外切平面投影算法五个部分。整个算法结合微机自带显卡中的图形处理器GPU,保证图像处理的实时性要求。同时由于OpenCV有较强的图像处理功能,使得算法描述非常简单。实验结果表明,整个算法实现效果较好,为后续的大型正交多幕特种电影集成技术及应用奠定了良好的基础。更多还原

【Abstract】 As an image representation of virtual environment,panorama has important applications in Virtual-Reality.With Open Source Computer Vision Library-OpenCV,a special case of curved panoramic projection is designed,that is,the annular cylindrical panoramic projection and rotation algorithm.The algorithm mainly includes the algorithm of cylindrical projection based on the horizontal plan image,the method of image mosaic,the effect of image rotation algorithm based on image capture,the method of image separation and the algorithm of outside the tangent plane projection.Because of OpenCV’s powerful image processing functions,the description of algorithm is very simple.It has been proved that the result of the whole algorithm is well,and it is also a good foundation for the integrated technology and application of the following large-scale orthogonal multi-screen special films project.更多还原
