摘要
在综合运用图像、图形处理、计算机网络、多媒体等技术的基础上,根据判读应用任务需求、判读人员作业习惯,将各种技术优势综合,提出了支持大型判读任务的、多机方式下的"遥感影像群判读系统"的解决方案及其计算机实现技术方案。首先分析了该技术的研究现状、技术背景和特点,然后提出了群判读的设计策略、基于客户端/服务器的总体框架结构、具体功能及其实现方法。引入"项目管理"的概念,将地理信息系统、网络技术集成到系统中,为使判读人员通过网络环境以协作方式判读,进一步提高工作效率提供了技术环境,也为遥感与地理信息系统的集成提供了可借鉴的新方法。
This paper introduces the strategy of system design for GrIS,its functions,the system structure and the implement technology in detail.To take account of the requirements of the tasks,procedures and manners of interpretation,the design of GrIS has integrated some techniques including image processing,graphics,computer network and multimedia.This lets GrIS support the interpretation to complete in both single-computer mode and multi-computer mode with client/server structure in LAN and WAN environment.Due to this ,its functions consist of three levels including module functions,functions in single system mode and functions for group-based cooperative working.So,GrIS can easily deal with task assignment,interpretation progress monitoring,accuracy and efficiency assessment,and results integration from different computers connected by network ,and so on.
