Abstract

QR 2D kodovi sadrže velike količine informacija na malom prostoru. Do

problema može doći ukoliko je kod oštećen i njegovim očitavanjem ne možemo doći do

željene informacije. U ovom diplomskom radu istraživati će se koliko oštećenje na QR

2D kodu nastalo na primjer u transportu, prilikom ispisa koda utječe na čitljivost koda s

obzirom na njegove parametre kodiranja i koji programi za očitavanje kodova su se

pokazali kao najpouzdaniji ukoliko je kod oštećen. Također će se istražiti koliko stupanj

oštećenja koda ovisi o njegovoj čitljivosti. Teorijski dio rada govori nam kako je nastao

2D kod, koje su najpopularnije vrste 2D kodova, što je QR 2D kod, kako ga generirati,

očitati i primijeniti. Iz istraživanja provedenog u eksperimentalnom dijelu saznati ćemo

kako različiti parametri kodiranja koda utječu na njegovu čitljivost, jer svaki QR 2D

kod u sebi ima ugrađen sustav ispravljanja pogrešaka. Saznati ćemo i koji od trenutno

najpopularnijih programa za očitavanje QR 2D kodova su uspjeli očitati oštećeni kod.

Abstract (english)

QR codes contain large amount of information on a small place. Problem can

occur if the code is damaged and its reading can not get you the desired information.

This thesis will explore how such damage occurred in transit or in printing process

affects readability depending on encoding parameters and which programs for reading

codes have proved to be most reliable if the code is damaged. We will also explore how

level of damage depends on code readability. The theoretical part of the thesis tells us

history of 2D codes, which are the most popular types of 2D codes, what is a 2D QR

code, how to generate, read and apply 2D QR code. From research conducted in the

experimental part we'll find out how much damage on the code can affect its readability

beacuse every program possesess error correction system. We will also find which of

the most popular programs for code reading were able to read the damaged code.
