Research on Vectorization and Recognition for Engineering Drawings: a Survey
Yunfei Shi · Journal of Engineering Graphics · 2008
Vectorization and recognition for engineering drawings is currently one of the most active research topics in the domain of pattern recognition.This strong interest is driven by a wide spectrum of promising applications in many areas such as 3D reconstruction,information interchange,content-based retrieval to engineering drawings,2D understanding for engineering drawings and so on.This paper reviews recent development level and recognition methods of vectorization and recognition for engineering drawings,and provides a comprehensive survey of research history and the state-of-the-art in raster to vector conversion for engineering drawings,and analyses and compares the advantage and disadvantage of all existing model.Research difficulties and development tendency in future are clearly discussed.Finally,some future directions in vectorization and recognition for engineering drawings are also provided.
