Position point compensation optimization method and system

The invention provides a position point compensation optimization method and system. The method includes the steps of receiving input writing pressure; judging whether or not the writing pressure reaches a preset pressure threshold value; when the writing pressure reaches the preset pressure threshold value, generating an image acquisition instruction according to the writing pressure; acquiring afirst bitmap image corresponding to a position point of a nib according to the image acquisition instruction; performing angle iterative processing on the first bitmap image according to preset stepsize data and preset angle range data to generate a second bitmap image; calculating the position of the nib according to a preset offset amount and a coordinate of a center point of the second bitmapimage, wherein the offset amount is the offset amount of the position of the nib and the coordinate of the center point of the second bitmap image. In this way, when the position of a hold pen is changed, the position of the n
