摘要
全景技术已经成为三维地理信息系统中不可或缺的部分,为探索网络环境下大幅全景图快速实时显示方法,该文提出一种将全景图进行分片切割的模型,并利用Flex技术根据可视区域进行分级分片加载显示。通过与全图加载显示的速度进行比较,切片模型能够有效提高全景图的加载显示速度。
Panoramic technology has become a part of 3 D GIS, the purpose of this paper is to improve the effi- ciency of panoramic image real-time displaying in the network. This paper provides a model of cutting. Pano- ramic image is cut into fragments, and then compared with the whole panoramic image in the speed of loading and displaying based on the Flex technology at the same viewing area. Compared with whole loading methods, this model can improve the efficiency in the speed of loading and displaying panoramic image.
