Variations on the Analysis of Architectural Drawings

Few teams have been dealing with the analysis of architectural drawings. Lately, our team has begun investigation in this field. This paper presents our first results. After a brief introduction to the specificities of architectural drawings and a short review of existing work, we describe the low-level processing steps we have implemented: segmentation, vectorization and detection of arcs, loops detection. In the present state of our work, we have investigated two complementary techniques for higher-level analysis; one is based on geometric analysis and symbol recognition, the other relies on the idea that architecture is a combination of spaces, and is therefore based on spatial analysis. We present our current results with these two techniques, and we suggest a number of perspectives for the continuation of this work.
