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

[0008] 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 The trajectory feature value is sent to its handwriting recognition unit for recognition, and the handwriting recognition result is checked by the OCR unit and the comparison correction unit to improve the recognition rate.

[0009] 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 according to the received instructions.

[0010] The digital image acquisition modu...

Abstract

The invention relates to a handwritten input device in the type of digital image acquisition and an inputting method thereof, and belongs to the technical field of computer input equipment. The invention comprises 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 connection relations between all the modules are as follows: the power management module is connected with the main control module; the main control module is connected to the identification module through the computer interface module; the image acquisition module is connected with the image transmission module; the image transmission module is connected to the identification module through the computer interface module. The invention solves the problems of high technical requirements to track acquisition equipment and limited track sampling range in prior art, avoids the professional requirement to a sensor by the handwritten input device, improves input speed and discrimination, realizes the intelligent digital input for dynamic handwritten file rapidly, inerrably and efficiently.

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. technical background [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...
