基于虚拟全景及漫游的视景仿真技术开发

Development of Visual Simulation Technology Based on Virtual Panorama and Roaming

针对电视跟踪系统的开发费用高、周期长的现状,讨论基于虚拟全景及漫游算法的视景仿真技术.详细论述了全景图像的生成及漫游算法,通过虚拟环境系统模型与全景图成像模型的建立,在漫游算法的基础上完成电视跟踪系统的视景仿真.结果显示:基于虚拟全景及漫游的视景仿真技术,可以加快视图的绘制,更具备真实感,并且方便提取相对应的视景图象.

In view of the current situation of TV tracking system development of high cost and long cycle, the visual simulation technology based on virtual panorama roaming algorithm we discnss. The generation and roaming algorithm of panoramic images was discussed in detail, through the establishment of virtual environment system model and the panorama imaging model, completes the visual simulation of TV tracking system based on the roaming algorithm. The result shows： the virtual simulation technology based on virtual panorama and roaming, can speed up the view of the map, more realistic, and is convenient for extracting correspondent visual image.
