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.
