【Abstract】 This paper presents the digitized processing method for lofting Drawing.Firstly,the author has introduced the realization course of the digitized lofting drawing.Then based on the characteristic of lofting drawing some key algorithms,such as the grey image binarization and refining,the fitting curve and mosaic for the format-separated scan images,are proposed.And finally taking some lofting drawing plates as examples the feasibility of the method have been verified through the module procedure.Case Analysis show that the digital lofting drawing processing method has a high recognition accuracy,and has using value of projects in the digitization manufacture of aircraft.更多还原
