AI Technical Summary

Problems solved by technology

The outer side of the existing infrared touch screen needs to install an infrared tube, which affects the compactness of the structure, and the cost of the infrared touch screen is still high, and the resolution is low
The structure of the laser electronic whiteboard system is relatively complex, so the cost is also high, and installation and debugging are difficult. During installation, professionals are required to locate the laser scanning part. Inaccurate positioning or small movements during use are likely to cause misoperation, and even cause malfunction. Use is therefore very limited

Abstract

The invention discloses an electronic writing device based on an optical image positioning technology. According to the electronic writing device, an optical image positioning module, a display screen module and an embedded module are arranged, image information of a writing brush on a display screen is collected by two image collectors of the optical image positioning module, meanwhile, image information obtained after the writing brush and the display screen are contacted is calculated in combination of relative positions of the two image collectors and the display screen, the image information is displayed through the display screen module, and a paperless writing process of the writing brush is realized.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology and relates to an electronic writing device based on optical image positioning technology. Background technique [0002] Optical imaging technology is a new type of touch technology suitable for medium and large-sized touch screens developed rapidly in recent years. Its working principle is to place two cameras on the adjacent corners of the touch screen, and continuously capture the movement changes of objects on the touch surface through the cameras. The influence of infrared rays is used for positioning. When the object on the touch surface is clicked or moved, the camera will quickly determine the touch position according to the object's occlusion of light, and then accurately judge the touch point or analyze the touch gesture to realize the corresponding functional operation. [0003] Since the basic technical principle of optical image touch technology is to judge the touch position...
