The “Automatic Hyperlinking of Engineering Drawing Documents” IEEE paper showcases a scientific understanding of the challenges contractors, architects, and engineers face every day.
The paper’s value to builders is what prompted IEEE to accept research for DAS 2016. Here are the highlights from the process detailed in the “Automatic Hyperlinking” paper.
Construction Documents Are a Productivity Problem
It’s obvious that construction projects need blueprints or drawing documents. But it may come as a surprise that those very documents hamper the building process. The core problem is the inefficiencies of manual document navigation and indexing. Automatic hyperlinking solves this problem.
The Technical Challenge of Automatic Hyperlinking
There are two OCR (optical character recognition, or how the computer reads text) software standards: ABBYY and Tesseract. Both have trouble extracting information from the complex characters of a drawing sheet.
The Solution: Custom OCR Engine Designed to Handle Text-Graphics Separation
To overcome the limitations of the ABBYY and Tesseract OCR engines, our engineers built their own in-house engine. The custom engine allows the technology to dynamically divide character images to extract the accurate information.
The result: ARC’s computer scientists solved the serious issue of inefficient document navigation—a problem that has existed nearly as long as construction and architecture work. It isn’t simply a technical achievement that IEEE honored. It’s the fact that auto-hyperlinking drastically improves the work of a whole industry. An industry that happens to build our world.
