Solution Overview
Problem
Conventional paper isometric drawings in piping systems are non-intelligent, inconsistent, and time-consuming to convert into digital formats, leading to errors and inefficiencies in plant planning and construction.
Innovation Solution
A method and system that utilize advanced image processing and deep learning to transform 2D isometric drawings into intelligent 3D geometry configuration data, generating a 3D digital twin of the piping system, which can be exported in a standard format like Piping Component File (PCF) for use in 3D piping design tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual conversion of paper isometric drawings into digital format is performed, then digital piping data can be obtained, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent replaces the manual mechanical conversion process with an automated image processing system that uses computer vision algorithms to extract piping component information from paper isometric drawings and directly generates digital piping data, eliminating the need for manual data entry and conversion
Solution Approach 2:
The patent creates a digital replica (copy) of the paper isometric drawing by processing the image to extract and represent piping components, fittings, valves, and other elements in a digital format that preserves all necessary information while enabling computational processing
2Adaptability or versatility
If conventional paper isometric drawings are used, then existing piping system documentation is maintained, but the drawings are non-intelligent and cannot be transformed into 3D models
Solution Approach 1:
The patent transforms 2D isometric drawing information into 3D spatial coordinates by analyzing the isometric projection geometry and converting the flat drawing coordinates into three-dimensional spatial representations that can be used for 3D modeling and digital twin creation
Solution Approach 2:
The patent replaces the non-intelligent paper drawing with an intelligent digital representation that automatically extracts and stores spatial coordinate information, enabling the data to be transformed into 3D models without manual intervention
3Productivity
If manual conversion of thousands of paper isometrics is performed, then complete digitalization can be achieved, but the process becomes extremely time-consuming and expensive
Solution Approach 1:
The patent replaces manual conversion operations with an automated image processing system that can process multiple drawings in parallel, dramatically increasing the throughput of digitalization while reducing the total time required to convert thousands of isometric drawings
Solution Approach 2:
The patent performs preliminary processing of the paper isometric drawings by scanning or photographing them to create digital image files, which then can be automatically processed in bulk using image recognition algorithms, preparing the data for efficient batch conversion

AI summary
A method of generating digital piping data from a paper isometric image. The method includes receiving a 2-Dimensional (2D) isometric image corresponding to a piping structure. The 2D isometric image comprises one or more piping components corresponding to the piping structure. The method also includes identifying at least one a direction, an orientation, a name, and dimensions of each of the piping components in a 3D space. The method further includes identifying 3D coordinate information corresponding to a start point and an end point of each of the piping components. Furthermore, the method includes generating 3D geometry configuration data corresponding to each of the piping components based on the corresponding identified 3D coordinate information, and the corresponding at least one of the direction, an orientation, and a dimension in a predefined standard format.
