Problems solved by technology

Therefore, this handwriting input device must use special resistive or electromagnetic sensors, such as handwriting boards, touch screens, electronic whiteboards, etc. to sample the writing trajectory data, which requires high technical requirements for trajectory acquisition equipment, and due to the limited range of sensors. The range of trajectory sampling, that is, the handwriting area also has certain requirements, which is inconvenient to use

Embodiment Construction

[0013] This device is connected with the control computer or other equipment that needs handwriting input, and its structure principle is as follows: figure 1 As shown, the recognition module provides an interactive interface for the user to set the shooting speed, range and definition requirements of the image acquisition module, that is, the camera equipment, according to the handwriting area, and compare the image files captured by the image acquisition module to obtain the handwritten Trajectory feature value is transmitted to its handwriting recognition unit for recognition to generate handwriting recognition results, and the handwriting recognition results are checked by the optical character recognition (OCR) unit and the contrast correction unit to improve the recognition rate.

[0014] The main control module is connected with the recognition module through the computer interface module, and instructs the image acquisition module to complete corresponding actions accor...

Abstract

A digital image collection type handwriting input device and an input method thereof belong to the technical field of computer input equipment. The present invention includes: a main control module, a computer interface module, a power management module, an identification module, an image acquisition module, and an image transmission module. The module is connected to the identification module, the image acquisition module is connected to the image transmission module, and the image transmission module is connected to the identification module through the computer interface module. The present invention solves the problem of high technical requirements for trajectory acquisition equipment and limited trajectory sampling range in the prior art, can avoid the professional requirements of handwriting input devices for sensors, improve input speed and recognition rate, and realize fast and error-free dynamic handwritten documents , Efficient intelligent digital entry.

Description

technical field [0001] The invention relates to an intelligent handwriting input device. Specifically, the handwriting input device obtains writing track data in a digital image collection mode, recognizes it through recognition software, and achieves the purpose of intelligent input, and belongs to the technical field of computer input equipment. Background technique [0002] At present, most of the handwriting input devices are trajectory acquisition type, and the way to realize handwriting input is: the computer collects the characteristic value of the operator's writing trajectory on the input device in real time, that is, the coordinate points with the input device plane as the coordinate system and the writing order sequence, and input the characteristic value of this trajectory to the computer, and then recognize it through a special recognition software, and convert the characteristic value of the handwritten trajectory into the corresponding internal code of the comp...
