Method for smooth processing of optical touch handwritten fonts

The invention relates to a method for smooth processing of optical touch handwritten fonts. Function modules comprise an optical sensor signal processing unit, an image signal interface unit, a self-adaptive tracking and adjusting unit, and a signal storage unit. The method for smooth processing comprises the following steps of enabling the optical sensor signal processing unit to collect and process image signals displayed on a touch screen; enabling the image signal interface unit to transmit the received perceptual image signals of the optical sensor signal processing unit into the self-adaptive tracking and adjusting unit; enabling the self-adaptive tracking and adjusting unit to carry out self-adaptive iterative computation and processing on the transmitted perceptual image signals, and correcting the touch positions of the current points of the images; and transmitting the image data after being subjected to the self-adaptive tracking and iteration into the signal storage unit for storing. The method has the advantages that the robustness is obviously improved, the optical touch handwriting is smoother, and higher timeliness, accuracy and stability are realized. In the industrial mass production mode, the easy implementation is realized, and the qualified rate of the mass production is high.
