The Research on Edged Detecting in CNC Engraving Technology Based on Reverse Engineering

Currently, the ancient calligraphy and painting are widely used in decoration screen; however, the processing technic is normally based on manual manipulation. Normally, this kind of processing is not efficient, and with highly cost. In addition, it could not maintain the original artistic style in maximum. the paper proposes to process the sculpture of ancient calligraphy according to its photo, by adopting the CNC technology based on reverse engineering method, which enables to mostly keep the original artistic style, and to create the CNC code automatically with the assistant of image processing to achieve intelligent machining.
