Abstract:
The oncept of adjacent relativity between drawing entities is
proposed. The related region is defined and the adjacent scale is
discussed for the purpose of that computer can have toleration
to drawing error in some degree. The algorithms of adjacent
relativity detection between line segment and window, line
segment and line segment, point and window, point and point are
discussed in detail. The author have implemented these detection
algorithms with program language of visual C++ and applied it to
view segment and feature extraction in mechanical part drawings.
Experiment results have demonstrated the efficiency of these
algorithms.
