一种图像获取及处理方法在油气管道线路工程中的应用

Application of Image Acquisition and Processing Method in Pipeline Engineering of Oil and Gas Pipelines

在油气管道项目建设设计过程中,线路工程踏勘是一个必不可少的关键环节。踏勘过程中获取的第一手图像资料是线路工程技术方案制定和报告编制的依据,也是线路路由方案综合评价的基础和输入条件。目前,传统的图像资料获取及处理方法过于依靠人脑记忆,效率低下,容易造成错乱混淆。笔者在线路工程踏勘及后期的资料整理中,引入了新的基于地理信息系统的图像自获取及批处理技术,将图像自获取地理信息属性、批处理转换和线路工程地理信息系统数据库相结合,对图像获取及处理的方法手段进行了改进,提高了效率,增强了图像资料信息的准确性和可溯性。

The pipeline engineering reconnaissance is an indispensable step in oil and gas pipeline construction and its design. The images captured from the reconnaissance were basics for engineering schemes and reports, and also were the basics and inputs of routing comprehensive evaluation. Traditional image capturing and editing method relies on brain memory. It is low efficient and error-prone. The paper introduces a new image capturing and batch editing technology basing on geotechnical information. Combining the geotechnical information auto-gathering, batch editing and engineering geotechnical information database, the technology will be an improvement on image capturing and editing. It will make the process more efficient, and make the images information more precise and traceable. The method has been used in pipeline routing comprehensive evaluation in several projects including Papua New Guinea project.
