Automatic analysis and simplification of architectural floor plans Build Status codebeat badge

This software is an architectural floor plan analysis and recognition system to create extended plans for building services.

Abstract

The goal of this work is to do a fast and robust room detection on floor plans. The idea is, that a wide range of non standardized floor plans can be analyzed, time efficient, with little drawbacks in its precision. The used workflow consists of several algorithms, that are combined to deliver the expected result. It consists of Morphological cleaning for noise removal, Machine Learning and Convex Hull closing for gap closing and a Connected Component analysis for the final room detection. It is the best result out of different approaches that were tested. All of the algorithms used, use an image of a plan as the start for detection and return the location and size of each room as a CSV-table or SVG-vectors. The software is prepared to return the rooms as a DWG- or DXF-Format for a CAD-Program, but the license for a library, to convert the format, is not finally evaluated. The algorithm implemented, shows improvement in room detection accuracy, compared to similar works done in the last few years.
