Abstract:
      An approach of computer geometric pattern recognition, which is based on semantic knowledge of an engineering structure sketch, is presented in this paper. The approach for recognizing geometrical topology and load environment in an engineering structure analysis sketch combines fast template matching, semantic recognition and the traversal of tree grammar, and then generates the data files which are required by application software. Therefore ,the specific format of initial data files of application software can be masked.
