20.500.12556/RUL-30725 Sistem avtomatskega prepoznavanja registracij – APR Automatic number plate recognition system - ANPR V prvem delu diplomske naloge sta predstavljena vedno bolj razširjen trend avtomatskega prepoznavanja oznak na avtomobilskih registrskih tablicah (APR) in njegova vloga v modernem svetu. Prikazani so praktično vsi primeri uporabe te tehnologije, ki so danes na voljo. Kot zaposleni v podjetju Janez, d. o. o., sem dobil nalogo razviti in sestaviti cenovno ugoden sistem APR, združljiv z ostalo opremo, ki jo podjetje proizvaja. Problem, ki ga je bilo treba rešiti, so nenormalne situacije, ki jih povzročajo nezaželeni gosti parkirnih hiš in parkirišč. Ker gre za javne površine, do katerih ima dostop praktično vsak, ki z vozilom vzame parkirni listek, je cilj določenim osebam dostop omejiti. Prav zato sem se osredotočil na sistem, namenjen uporabi na vstopnih in izstopnih točkah, kjer se vozilo ustavi, za katerega sem napisal tudi del programske opreme. Rezultat uporabe tega sistema je zmanjšanje deleža nezaželenih gostov, zaradi česa se poveča varnost in izboljša plačilna disciplina parkirišča. Celoten proces izvedbe takšnega sistema je relativno zahteven, ključnega pomena pa sta pravilna nastavitev primerne kamere, saj mora zajeti kakovostno sliko v vseh pogojih, in dobra programska oprema za prepoznavo registracije. Ugotovljeno je bilo, da trenutno takšen sistem sicer ni dovolj zanesljiv za popolno nadomestilo obstoječih sistemov pristopne kontrole in parkirne avtomatike, vsekakor pa gre za priporočljiv in učinkovit pripomoček za urejanje dostopnih pravic. Sistem tudi v praksi deluje v eni izmed parkirnih hiš, s katerimi razpolaga podjetje Janez, d. o. o., iz analize učinkovitosti delovanja na tem objektu pa izhajajo tudi navedene ugotovitve. In the first part of the diploma thesis the focus is on the increasing use of automatic number plate recognition systems (ANPR) and their role in the modern world. Almost all of the practical applications of this technology available today are also presented. As an employee of company Janez, I have been given the task to develop and assemble a cheap ANPR system that would be compatible with the equipment that we produce. We needed to find a solution to the problem of unwanted visitors of parking lots and garages. Because these facilities are publicly accessible to anyone that takes the parking ticket at the entrance, the goal is to prevent access to blacklisted individuals. That is why I have developed a program focused on a system that is intended for use at entry and exit points where the vehicles stop. The result of this system is a decrease of unwanted guests, increase of safety and improved payment discipline. The process of introducing such a system is quite complex, the key part being the correct camera placement and settings as it has the most important role in capturing quality images in all conditions. Furthermore, a significant role is also played by good ANPR software. It has been established that such a system is not reliable enough to completely replace the existing access control systems and parking automatics, but is an effective and recommended addition to access supervision and control. This system has been put into practice in one of the parking garages that is managed by company Janez, and the findings of this diploma thesis originate from the analysis of its practical use.
