A New Method of Image-based Virtual Space based on image array interpolation

摘要

As an important means of virtual reality, image-based virtual space has become the key technology of strategy implementation of Digital Earth and Digital City, and the authenticity of walkthrough simulation is the focus of image-based virtual space systems. In this paper, we first analyzed the shortcomings and deficiencies of existing virtual space, and then proposed image array interpolation method. We inserted image array between adjacent scenes, and loaded it within the set time at the change of the scenes to achieve smooth transition. Finally, we designed and a free image-based virtual space system based on ArcGIS Server and Flex. The results show that this method is feasible and generally applicable.
