摘　　要：针对Matlab、ImageJ等数字图像处理计算资源无序分布、多元异构、无法实现计算协同、普通用户难以使用等特点,提出了一种面向最终用户编程的数字图像处理虚拟实验平台模型。该平台采用面向服务的体系架构开发,将地理位置分布的计算资源统一封装为服务构件,向最终用户屏蔽图象处理设备分布、异构的特性。为了形式化表达实验设备之间的复杂连接关系,设计了一种面向领域的实验流程描述语言。基于实验流程描述语言和服务构件动态组合技术实现了分布式图像处理实验设备之间的动态聚合;与已有的工作相比,该平台有效地解决了网格环境下异构虚拟实验设备的资源共享、动态协同和运行调度问题,为用户提供了一种不受时间、地点以及实验设备约束的数字图象处理虚拟实验环境。Since the distribution and heterogeneity of digital image processing recourses such as Matlab,ImageJ,it is difficult for end-users to use them and make these resources work together.To address these problems,a business-end Programming oriented virtual laboratory platform,named DIPVL,was proposed for digital image processing.This platform was implemented by using service oriented architecture（SOA）.In the platform,computing recourses at different geographical locations were encapsulated using Web services.To describe the relationship between virtual instruments formally,a domain-oriented service composition description language was designed.Based on this language and dynamic service composition,distributed computing resources were glue-less connected and integrated dynamically.Comparing with existing virtual laboratory for digital image processing,DIPVL effectively solved some general problems of resources sharing,dynamic coordination and resources schedule between with heterogeneous virtual devices.DIPVL can provide a kind of experiment environment that can＇t be restricted by time,location or experiment equipment,and teaching and scientific research can be unified.
