摘　　要：针对目前基于视频融合的增强现实系统不能为用户提供感兴趣点及其周围综合地理信息的问题,开发一种3DGIS与多视频融合的系统。介绍3DGIS与多视频融合的系统的框架,研究基于投影纹理映射的虚实融合技术、三维重建技术,实现多路视频信息与三维场景模型、地理信息、地物的各种属性信息的融合。Considering that present video fusion based augmented reality system can not provide users with comprehensive geographic information of their interested points as well as their surroundings,the authors have developed a 3DGIS and multiple videos fusion system.The paper introduces the framework of the 3DGIS and multiple videos fusion system,studies the real/imaginary fusion and 3D reconstruction techniques based on projective texture mapping,and implements the fusion of multi-channel video information with three-dimensional scene model,geographic information,and various properties information of ground objects.
