Calculation method and device for laser marking graph correction value and computer readable storage medium

The invention discloses a method for calculating a laser marking graph correction value. The method comprises the steps that obtaining the initial size of a first graph, and the first graph is a graphmarked according to initial parameters; calculating according to a preset algorithm and the initial size to obtain a correction reference value of the initial parameter; marking is carried out according to the correction reference value, and obtaining a marked second graph; obtaining an error of the second graph according to the second graph and an initial parameter; judging whether the correction reference value meets preset correction precision or not according to the error; and if yes, taking the correction reference value as a correction value for laser marking. The invention further discloses a laser marking graph correction value calculation device and a computer readable storage medium. According to the method, the laser marking process can be corrected, a correction value in the laser marking process is o
