Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] refer to figure 1 , figure 1 It is a schematic diagram of the stylus structure of the hardware operating environment involved in the solution of the embodiment of the present invention.

[0041] Such as figure 1 As shown, the stylus may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein, the communication bus 1002 is used to realize connection and communication between these components. The user interface 1003 may include a display screen (Display), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. Optionally, the network interface 1004 may include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 can be a high-s...

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 ...
