基于Web Service技术的岩芯图像显示研究

Research on displaying of core images based on Web Service technology

目前,随着实物地质资料管理工作的持续推进,越来越多的钻孔岩芯被采集并扫描数字化,如何利用现代互联网技术,将扫描的岩芯图像信息向社会公众提供服务是急需解决的问题。本文主要阐述在开发重要岩芯图像服务系统过程中,解决岩芯图像信息在客户端显示的三方面问题:一是单张岩芯图像太大;二是全孔岩芯图像连接起来显示太长;三是岩芯图像和描述信息深度计算标准不统一。通过充分利用Web Service技术,首先利用缩略图技术将岩芯图像统一压缩,然后利用图像延时加载技术即lazyload加载岩芯图像信息,最后利用Ruler控件设置岩芯深度标尺,作为岩芯图像和岩性描述信息深度对比的中间组件,最终完成全孔岩芯信息的整体显示。

At present,as the sustained advancing of physical geological data management,agrowing number of drilling cores were collected and scanned digitized.How to make use of modern Internet technology to provide core image information to the public is an urgent problem.In the development process of important core image service system,this paper describes three aspects of problems encountered in the core image information displayed on the client:1one single core image is too large;2connected full-hole core image is too long to display;3The depth of core image and description are not uniform.By using Web Service technology,Firstly,use thumbnail technology to compress the core images.Then use caching technology to load core image information.Finally,use Ruler to set core depth ruler,which as a intermediate assembly between the core image and lithologic descriptions.Finally,the core image of whole hole are displayed completely.
