Abstract: This article introduced a sketch recognition method for conceptual design.The graphic symbol was regarded as composition of multiple single stroke graphs.First,the types of individual primitives were identified and the spatial relationship between them was extracted.Then the structure of standard graph was defined by the method of structure matching.A comparison between the graphics drawn by user and the standard template was made to filter out the graphs with the same structure.Then Fourier shape descriptor was used to describe graphic shapes to calculate the shape similarity,and filter out the graphs with the same shape.By combining the two features of the structure and shape,we could quickly and accurately identify the motion mechanism,extract engineering semantics and realize the capture of design intent.

Key words: Sketch recognition,Shape descriptor,Conceptual design,Structure matching
