Image recognition processing method and system

The embodiment of the invention relates to an image recognition processing method and system. The method comprises the following steps: receiving image data and a writing pressure corresponding to theimage data; performing binarization processing on the image data to obtain a first lattice image; intercepting a second lattice image in the first lattice image; performing lattice recognition processing on the second lattice image to obtain a plurality of lattice points; intercepting a third lattice image in the second lattice image; obtaining encoding information according to the direction of acentral point of an offset grid of the lattice point in the third lattice image; judging whether the encoding information matches a code value in a codebook list; if not, performing angle iteration processing; if yes, generating a central point coordinate of the third lattice image according to the code value; and obtaining a corresponding line width value according to the writing pressure, and generating a data packet ac
