Light pen track identification system and method

Abstract

The invention discloses a light pen track identification system which is applied to electronic equipment. The identification system comprises a light pen, a camera, a track following unit, an image identification unit and a display unit, wherein the end of the pen is provided with a pressure sensing light, the camera collects a track picture of the light pen according to the indication of the pressure sensing light, the track following unit follows the track of the light pen on the collected track picture and records the track to a track recording picture, the image identification unit carries out identification processing on the track recording picture, and the display unit displays an identified result on a screen of the electronic equipment. The invention can be conveniently used for character input of the electronic equipment.

Description

technical field [0001] The invention relates to recognition technology, in particular to a character recognition system and method based on light pen trajectory tracking. Background technique [0002] At present, more and more electronic devices such as mobile phones, personal digital assistants (PDAs) and computers have added handheld input devices, such as touch screens, whose function is to use a special pen or finger to write text in a specific area, The trajectory of the pen or finger can be recorded by various methods and recognized as text. For the convenience of use, an ordinary keyboard and a mouse are usually installed on the electronic device, but some handheld input devices are not suitable for adding a keyboard and a mouse because of their volume. [0003] And, for an electronic device that utilizes a touch screen to provide an input platform for a handheld input device. Since the touch screen has a high economic cost, the manufacturing cost of these electroni...
