Baigiamajame magistro darbe “Interaktyvus transporto numerio atpažinimas” nagrinėjami bei pritaikomi stebėjimo zonos išskyrimo, fono eliminavimo, Gauso, Sobel metodai ir algoritmai. Taip pat atliekama metodų bei filtrų analizė. Tyrimo eigoje buvo sukurta programa skirta duomenų įvedimui į kompiuterį iš vaizdo kameros, vaizdo failo arba interneto. Atlikti eismo filtravimo eksperimentai, vartotojų patogumui įgyvendintas įrankis skirtas gauti ir pateikti apdorojimo rezultatus į mobilujį telefoną. / This work presents an approach to license plate localization and recognition. A proposed method is designed to perform recognition of any kind of license plates under any environmental conditions. The main assumption of this method is the ability to recognize all kinds of license plates which can be found in an individual picture. The algorithm takes a raster image as an input, and yields the position of a plate in the image. After the position is determined, the algorithm can determine the locations of characters on the license plate, which could be easily combined with an OCR algorithm to convert the license plate number into an ASCII string. User could view collected license plate localizations results with mobile phone, which has JAVA (MIDP 1.0) support and internet access. Future work could focus on determining the positions of characters more precisely. Determining the correct positions of all characters in a license plate would dramatically improve the results of the license plate recognition.
