Problems solved by technology

[0009] There are different defects in the above character segmentation methods: for example, the double-frame writing method limits the writing position of the user; the full-screen single-character writing method slows down the input speed, and the full-screen multi-character writing method speeds up the input speed. The accuracy of character segmentation is low; and the latter two input methods will be recognized without completing the input due to poor control of the input delay, which greatly reduces the accuracy of recognition and brings inconvenience to handwriting input

Embodiment Construction

[0030] figure 1 It shows the three-dimensional movement trajectory 3 of the coordinate indicator 2 inputting the character at the coordinate detector 1, wherein the coordinate indicator 2 is used for character input, and transmits its three-dimensional movement trajectory data, and the coordinate detector 1 receives the trajectory data signal.

[0031] figure 2 It is a technical principle block diagram of the method of the present invention, comprising the following steps: step (1) coordinate indicator input characters; step (2) coordinate detector real-time collection of coordinate indicator three-dimensional motion trajectory data; step (3) computer memory storage trajectory data; Step (4) measures the altitude letter of track data; Step (5) compares height information and the altitude threshold data preset by computer, when the altitude information is greater than the preset altitude threshold data, the character end sign is set.

Abstract

The invention relates to a character segmentation method, belonging to the technical field of computer pattern reorganization. The invention is characterized in that three-dimensional movement track data produced when the character is input by a coordinate indicator is collected by a coordinate detector; track data information is stored inside a computer memory; the height of the track data is measured to be compared with height threshold data preset in the computer; when the height is higher than the threshold data, the character input can be judged completely by the computer and then a character end symbol is set. The invention has the advantages of overcoming the shortcomings of the existing character segmentation, ensuring the accuracy of character segmentation to be accurate; the method can be widely applied in a handwriting input system, so as to improve the correct rate of handwriting reorganization.

Description

technical field [0001] The invention relates to a method for character segmentation, in particular to a method for segmenting input characters in the process of computer character recognition, and belongs to the technical field of computer pattern recognition. Background technique [0002] The emergence of tablet, mouse and tablet computer with handwriting function has improved the intelligence of ordinary computers. When using these handwriting input devices for computer text input, there are usually the following three character segmentation methods, and their manifestations are: [0003] 1. Double-frame writing - character segmentation using position change [0004] Usually, two specific input areas are artificially specified and displayed in boxes, and the user enters characters in the boxes one by one. When the input from the first box area is completed and the input is transferred to the second box area, The computer program completes the character segmentation accor...
