Abstract
U okviru ovog završnog rada izrađena je aplikacije za prepoznavanje prometnih znakova ograničenja brzine na učitanoj slici primjenom konvolucijske neuronske mreže. Za razvoj aplikacije korišteni su Keras te OpenCV. Za treniranje i testiranje aplikacije korištene su fotografije iz GTSRB baze podataka te vlastiti videozapis iz kojega su okviri spremljeni u zasebnu mapu. Kod detekcije znakova iz videozapisa pokazalo se kako elementi okoline prometnog znaka imaju znatan utjecaj na točnost njegova prepoznavanja. Također, utvrđeno je kako točnost prepoznavanja uvelike ovisi i o udaljenosti znaka od kamere. Unatoč tome, testiranje korištene metode je pokazalo kako je prepoznavanje znaka u većini slučajeva uspješno obavljeno i da je trening nad slikama koje čine bazu podataka odrađen uspješno.
Abstract (english)
An application for recognition of the speed limit road sign on the loaded photo is made within this bachelor’s thesis. Keras and OpenCV are used for the application development. Photos from GTSRB database, as well as own videos from which video frames are extracted and saved into a folder, are utilized for training and testing the application. Detecting the signs has shown that environmental elements have a very strong influence on accuracy of the sign recognizing. Also, it has been established that the accuracy depends on distance between car camera and the traffic sign. Nevertheless, testing of the presented method showed that the sign recognition was well done and that training, performed on images which make the database, was successfully carried out.
