Face handwriting input system and method based on image acquisition

Abstract

A face handwriting input system based on image acquisition comprises an input panel, an input device, a processing unit and a server platform for storing handwriting input content. Coordinate points are arranged on the input panel to form an input coordinate system, the input device comprises a writing surface, a pressure sensor and an image collector, the writing surface is in contact with the input panel during handwriting operation, and positioning points on the outer edge of the writing surface are contained in the view field of the image collector. The processing unit receives image information of the image collector, calculates handwriting input content and sends the handwriting input content to the server platform. The systrm has the advantages of high handwriting restoration degree, wide writing scene and the like.

Description

technical field [0001] The invention relates to the field of computer interactive handwriting input, in particular to a system and method for surface handwriting input based on image acquisition. Background technique [0002] With the development of handwriting electronic devices, handwriting input functions are applied in various aspects to replace traditional pen and paper writing, such as electronic signature, electronic drawing and so on. In the field of education, the emergence of intelligent classroom systems and learning systems has promoted the development of paperless and intelligent education, which not only saves resources, but also records the teacher's classroom writing and the completion of students' homework, effectively improving the quality of education. However, the handwriting input systems used in existing intelligent classroom systems and learning systems are usually touch-sensitive handwriting input systems that need to be used in conjunction with elect...

AI Technical Summary

Problems solved by technology

This data collection method only records the position of the point of the stylus tip, and the contact surface with the writing medium is the surface in real writing, and different shapes of the contact surface will form different handwriting, resulting in the writing effect input by the prior art and using traditional writing. tools vary

Although the simulated handwriting can be calculated through the readings of the pressure sensor of the stylus or other algorithms, there is still a deviation from the real writing effect, which is not conducive to guiding students to establish a correct understanding of writing in the learning process
