基于感兴趣区的空间数据获取研究

On obtaining of spatial data based on Region of Interest

根据当前空间数据获取存在的问题,提出一种基于感兴趣区的空间数据获取方法,即只获取那些选定空间区域中的、能显示出来的、影响显示效果的空间对象,这样可以减少数据传输量,提高响应速度。

In this paper,Region of Interest(ROI)of obtaining the spatial data method is proposed.This method only transmits the data which is selected,can be showed and affects the stereoscopic display quality.It can cause fewer transmissions and speed up the response.
