摘要
随着教育高速发展,教学演示越来越普遍,但是普通的激光笔已经远远不能满足需要,为了让使用者在教学、演示时最大限度的发挥肢体语言的优势,彻底解决以往在课堂和会议上使用鼠标的不便,研究一种搭载便携式激光键盘的激光笔设计是有必要的。文章对传统几何失真校正算法进行研究,提出一种不同角度的的校正算法,并以此构建一套实验装置,实验表明效果良好。
With the rapid development of education,teaching demonstration is more and more common,but the ordinary laser pointer is far from meeting the needs.In order to let the user maximize the advantages of body language while teaching and presenting,on the inconvenience of using the mouse to study a laser pointer with a portable laser keyboard design is necessary.In this paper,the traditional geometric distortion correction algorithm is studied,and a different angle correction algorithm is proposed.Based on this,a set of experimental apparatus is constructed,and the experiment shows that the effect is good.
