A Heuristic Method to Recognize Dimension Sets in Architectural Engineering Drawings

摘要

Recognition of dimension sets is a prerequisite for engineering draw- ings interpretation. A new heuristic algorithm for dimension sets recognition is presented in this paper. Following the recognized text strings, the algorithm rec- ognizes the dimension lines and other components of the dimension set according to the dimension set syntax. The advantages of this algorithm to the architectural engineering drawings are significant. A data structure of planar position index is used and evaluated. Experimental results are also presented.
