摘要
本文设计了一种基于红外技术的互动电子白板系统,该系统由红外摄像机、红外笔、普通电脑、投影仪和幕布5部分组成。其利用红外摄像机捕捉红外笔发出的光点,并将位置信息返回到电脑,实现互动电子白板的书写功能。互动电子白板软件采用C#语言和.Net平台,运用GDI+技术,实现了绘图、控制面板、屏幕定位等模块。系统界面友好、操作简单、使用方便,价格经济。
In this paper,a low-cost interactive whiteboard system based on infrared camera is proposed.The interactive whiteboard system is constituted by five parts： infrared camera,infrared pen,personal computer,projector and curtain.The function of interactive whiteboard is realized by the principle of capturing points come from infrared pen by infrared camera,then return position information to computer.The software system is developed by C# language and GDI＋ on the.Net platform.Three modules including drawing,control panel and screen positioning are implemented.This system is user-friendly,simple and easy to use.
