Abstract

U okviru ovog završnog rada je projektiran i programiran edukacijski robot skener pomoću programa MATLAB i Lego Mindstorms EV3 edukacijskog seta za sastavljanje.
Robot je trebao očitat polovicu A4 papira na kojem je zadan jednostavni matematčki zadatak od ukupno tri znaka.
Nastala matrica očitaka inteziteta svjetla se zatim pretvara u binarnu sliku nad kojom se vrši optičko prepoznavanje znakova.
OCR je baziran na izračunavanju centralnih momenta svakog znaka te njihovom usporedbom s unaprijed pripremljenim karakterističnim intervalima za svaki znak.
Nakon prepoznavanja znakova, MATLAB izvrši i ispiše rezultat zadatka.

Abstract (english)

Within this bachelor thesis, an educational robot scanner was designed and programmed using MATLAB and Lego Mindstorms EV3 training kit.
The robot was supposed to scan half of a paper size A4 on which a simple math task was written constiting of a total of three characters.
The resulting light intensity matrix is then converted into a binary image over which optical character recognition is performed.
The OCR is based on the calculation of the central moments of each character and their comparison with the pre-prepared characteristic intervals for each character. After recognizing the characters, MATLAB performs and prints the result of the task.
