%X According to the characteristics of tolerance in shape and relative position in engineering drawings,a new vector-based recognition algorithm based on key graphics characteristics and label character was proposed and implemented.This algorithm consisted of three main steps: firstly finding the key components,secondly searching other components according to the specific graphic syntax,thirdly judging the validity by characters.Experiment results indicate that this algorithm has powerful adaptability and high recognition.
