基于IDL语言的虚拟场景的重建和漫游

基于图像的建模和绘制方法与基于传统的几何绘制方法相比有很多优点，但是在场景几何参数未知的情况下，要实现单幅图片和图像序列的漫游，难度很大．论文对虚拟场景重建的目的和重要性以及佃技术的原理作了介绍．在佃技术的基础上，利用IDL语言根据透视投影关系和运动路径，为场景加入了一个近似的三维信息，并将前后图像的模型根据它们的位置关系串连起来实现了一种未知运动路径情况下的虚拟场景重建和漫游．

Construction and Wandering of Virtual Environment Based IDL Language

Compared with the traditional geometric approach,the approach of image-based modeling and rendering has many advantages.However,it is hard to implement modeling from one single picture if geometric parameter is not known.The purpose and importance of construction of virtual environment and theorem of TIP technique is introduced in this paper.Based on TIP technique,by means of IDL,perspective projection and moving path,the paper realizes the construction and its wandering of virtual environment with the unkn...
