Shumei Wang · Jisuanji gongcheng · 2007
Consistency checking between the scanned drawing and the electronic drawing is one of the important steps in the flow of electronic declaring.The electronic blueprint is transformed in vector form preservation drawn up by the cartography software(AutoCAD and so on) to the image document saved by the grid form,this grid image document is used to preprocess the scanned blueprint,and finally consistency checking is carried on between the scanned blueprint and the grid document using the wavelet transformation and the computation fractal dimension.The experimental result indicates that the algorithm can realize the consistency checking between scanning blueprint and the grid document well.
