Abstract:
This paper presents a novel approach for recognizing
and interpreting dimensions in engineering drawings. It
starts by detecting potential dimension frames, each
comprising only the line and text components of a
dimension, then verifies them by detecting the dimension
symbols. By removing the prerequisite of symbol
recognition from detection of dimension sets, our method
is capable of handling low quality drawings. We also
propose a reconstruction algorithm for rebuilding the
drawing entities based on the recognized dimension
annotations. A coordinate grid structure is introduced to
represent and analyze two-dimensional spatial constraints
between entities; this simplifies and unifies the process of
rectifying deviations of entity dimensions induced during
scanning and vectorization.
