Abstract
This strong interest to vectorization and recognition for engineering drawings 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 development level and recognition methods of vectorization and recognition of circular-typed graphics object for engineering drawings, and provides a comprehensive survey of research history and the state of the art in recognition conversion of circular-typed graphics object for engineering drawings. The approach of conversion circular-typed graphics object are divided into fitting-based methods, vector-based methods, global-based methods and integrated-based methods. The advantage and disadvantage of all existing model of circular graphics object are analyzed and compared. Research difficulties and development tendency in future are clearly discussed for engineering drawings. At the end of this survey, some detailed discussions on research challenges and future directions of vectorization and recognition for engineering drawings are also provided.
