Plant Drawing Symbol Pattern Matching for Fast Symbol Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently registering and detecting desired symbols from plant drawings used for construction, operation, and maintenance, as they struggle to accurately match symbol patterns and provide information related to symbols in these drawings.
Innovation Solution
A plant drawing symbol detection system that includes a control unit to acquire, display, and select symbols, register patterns, and detect matching symbols within the drawing, using a server device connected to a plant administrator terminal for efficient symbol detection and information provision.

Engineering Contradiction Analysis
1Productivity
If existing symbol detection technology is used, then symbol recognition can be performed, but it is difficult to efficiently detect and provide information about specific desired symbols from among multiple symbols in the drawing
Solution Approach 1:
The system segments the symbol detection process into distinct phases: pattern registration phase where desired symbol patterns are defined and stored, and detection phase where the drawing is analyzed to find matching symbols. This segmentation enables efficient detection of specific symbol types by separating the configuration step from the execution step, allowing users to register their desired symbol patterns once and then efficiently detect them across the entire drawing.
2Measurement precision
If pattern matching is performed on all symbols, then comprehensive detection is achieved, but the complexity of pattern registration and matching increases
Solution Approach 1:
The system performs preliminary action by requiring users to register desired symbol patterns in advance before the actual detection process. The control unit stores these registered patterns and uses them as templates for matching. This preliminary registration step simplifies the detection process by pre-defining what symbols are being sought, thereby reducing the complexity of real-time pattern matching while maintaining high detection accuracy through systematic comparison against registered templates.

AI summary
A plant drawing symbol detection system acquires a plant drawing that is used for construction, operation, and maintenance of a plant, displays the acquired plant drawing, accepts selection of a symbol that is desired from among a plurality of symbols that are present in the displayed plant drawing, registers a symbol pattern of the accepted selection of the symbol, detects, from the displayed plant drawing, all of the symbols each having a shape that is matched with a shape of the registered symbol pattern including the symbol that has been used for the selection, and provides a detection result related to the symbols.
