一种基于四叉树的大规模影像数据库构建方法

Method of Building Large- Scale Image Database Based on Quadtree

为了能流畅地漫游大范围的影像数据,必须使用影像金字塔技术,将影像的切片数据存入数据库系统,建立全区域的多分辨率影像数据库。使用数据库索引机制结合四叉索引树模型,可以完美地实现影像切片数据的高效检索,进而实现全区域影像的流畅漫游。

In order to smoothly roaming all image data in large -scale area , mustuse the image pyramid technology , and write the bi-opsy of the image data in the database system , building the whole area of multiresolution image database .Using the database index mechanism combined with Q -Tree model, can realize image slice data perfectly efficient retrieval , thus realized the full area image smooth roaming .
