Abstract

Abstract:

There exist plenty of pipelines drawings of the design and production in Chemical Enterprises, which are described by two-dimension projection. Some design errors of position interference among pipe segments often appears during pipeline construction. Several problems related to three-dimension reconstruction of pipelines were researched, including characteristic analysis of pipeline drawings, data pre-processing, data description, coordinate transforming, recognizing and matching of pipe segments and so on. Finally, three dimension data were generated among matching pipe segments.

Key words: Chemical pipeline drawing , , Three-dimension reconstruction , Recognizing and matching of information

摘要： 化工管道图大量存在于化工企业的设计和生产中,大多以二维设计图纸表达,在具体管道施工中常
