摘要
由于PDA(Personal Digital Assistant)的硬件资源有限,往往存在CPU主频低、内存小的缺点,海量遥感影像图的绘制成为在PDA上运行"空间信息移动服务系统"的一个技术瓶颈.为了克服这些限制,提出一种基于金字塔影像模型的分层组织和分块管理方法,应用多分辨率无缝影像数据库技术,将海量影像数据有序地组织起来,提高海量遥感影像的绘制速度.该技术已被成功地应用到"郑和一号船舶引航系统",效果良好.
Due to the limited hardware resources and the speed of display of PDA, rendering massive remote sensing image is a problem in PDA appliances, such as Spatial Information Mobile Serveice System. This paper presents a method based on image pyramid with multi-levels and multi-blocks structure to organize the massive remote sensing image and implement its rapid rendering. The methods has been successfully applied in a PDA to No. 1 Zhenghe Pilotage System at Xiamen Port.
