Abstract
U ovom radu prikazana je ideja izrade virtualne tipkovnice na principu web kamere. Kako bi došli do zadanog cilja, korištene su metode digitalne obrade slike, poput binarizacije, morfoloških operacija i filtriranja. Postavljen je algoritam koji omogućava ispis slova u bilo kojem programu na Windows operacijskom sustavu. Web kamera je pozicionirana na monitoru i snima područje ispod monitora gdje se nalazi tipkovnica isprintana na papir. Ukoliko prstom pokažemo na određeno slovo tipkovnice, postavljeni algoritam locira vrh prsta i odabrano slovo prikazuje u željenom programu. Prilikom izrade korišten je Image aquistion tool u programskom okruženju MATLAB. Najveći nedostatak prikazane metode izrade virtualne tipkovnice je brzina rada i osjetljivost na osvjetljenje prostorije.
Abstract (english)
This paper presents the idea of making the virtual keyboard on the principle of web camera. In order to reach the default target, methods are used that include digital image processing like binarization, morphological operations and filtration. Written algorithm enables printing letters in any Windows operating system program. Web camera is positioned on the monitor and it scans the area under the monitor, where paper printed keyboard is located. If the certain letter on the keyboard is pointed by finger, the algorithm locates the top of the finger and shows the selected letter in desired program. In making of this paper, Image aqusition tool in the programming environment of MATLAB was used. The biggest drawback of the virtual keyboard production method shown in this paper is the operating speed and its sensitivity in illuminated spaces.
