Abstract

Systems and methods for automating information extraction from piping and instrumentation diagrams are provided. Traditional systems and methods do not provide for end-to-end and automated data extraction from the piping and instrumentation diagrams. The method disclosed provides for automatic generation of end-to-end information from piping and instrumentation diagrams by detecting, via one or more hardware processors, a plurality of components from one or more piping and instrumentation diagrams by implementing one or more image processing and deep learning techniques; associating, via an association module, each of the detected plurality of components by implementing a Euclidean Distance technique; and generating, based upon each of the associated plurality of components, a plurality oftree-shaped data structures by implementing a structuring technique, wherein each of the plurality of tree-shaped data structures capture a process flow of pipeline schematics corresponding to the one or more piping and instrumentation diagrams.

Description

[0001] Cross References to Related Applications and Priorities [0002] This patent application claims priority from Indian Patent Application 201821045399 filed on November 30, 2018. technical field [0003] The disclosure herein relates generally to engineering schematics and, more particularly, to systems and methods for automated information extraction from piping and instrumentation diagrams. Background technique [0004] P&I diagrams include one of the most common schemas for representing engineering schematics. These diagrams depict the layout of the engineering process flow and the interconnected process equipment. For many years, piping and instrumentation drawings have been manually generated, scanned and stored as image files. These files need to be digitized for inventory management and updating, and for easy reference to the different components of the schematic. There are several challenging vision issues associated with digitizing real-world piping and inst...
