Abstract

The invention discloses a handwriting pen handwriting offset compensation method , the handwriting pen, a storage medium and a device. The method comprises the steps of collecting first coordinate information of a first starting code point and second coordinate information of a current code point through a camera; calculating a prediction distance between the first starting code point and the current code point according to the first coordinate information and the second coordinate information; judging whether the predicted distance is smaller than a preset error distance; and if the prediction distance is smaller than the preset error distance, obtaining a first intermediate code point between the first initial code point and the current code point, and moving the first intermediate codepoint and the current code point to a neighbor code point of the first initial code point. Whether an error is generated currently or not is judged through the predicted distance, and the first intermediate code point and the current code point are moved to the neighbor code point of the first initial code point when the error is generated, so that an arc between the first initial code point and the current code point is corrected into a straight line between the first initial code point and the neighbor code point, and handwriting offset compensation is realized.

Description

technical field [0001] The invention relates to the technical field of smart pens, in particular to a handwriting offset compensation method of a stylus, a stylus, a storage medium and a device. Background technique [0002] The camera and pen tip of the smart stylus are not on the same axis. Therefore, when writing with the smart stylus, the position recognized by the camera is different from the actual writing position. On the smart terminal connected to the smart stylus, it is displayed as a circular ring, or when drawing a straight line due to the slight rotation of the pen tip, the straight line displayed on the smart terminal contains jagged. The existing smart stylus realizes this distance compensation by adding a gyroscope, which has high cost and weak market competitiveness. Contents of the invention [0003] The main purpose of the present invention is to provide a stylus handwriting offset compensation method, stylus, storage medium and device, aiming to solve ...
