Abstract
Jedan od osnovnih problema kojima se bavi računalni vid jest detekcija i prepoznavanje objekata. U svrhu klasifikacije odnosno prepoznavanja prometnih znakova, u ovom radu je dana metoda zasnovana na detekciji značajki sa slike referentnog znaka iz baze podataka i usporedbi tih značajki sa značajkama fotografiranih prometnih znakova. Pri tome su se usporedila tri različita algoritma detekcije ključnih točaka: SIFT, SURF i ORB. Testiranje je provedeno na vlastito izrađenoj bazi od 130 testnih fotografija, gdje su u obzir uzeti prometni znakovi različitih oblika koji su fotografirani pod različitim kutovima. Prema dobivenim rezultatima prepoznavanja znakova, najveću točnost od 83 % postiže ORB algoritam kada se koristi izdvajanje najbolje uparenih ključnih točaka računanjem najkraćih udaljenosti, uz svrstavanje znakova u određene grupe prema njihovoj boji i obliku.
Abstract (english)
Object detection and recognition is one of the most importatnt tasks in computer vision. For the purpose of traffic sign recognition, this paper provides method based on detecting features from sign in referent database and comparing them with features from captured images of traffic signs. Also, three algorithms for keypoint detection were compared: SIFT, SURF and ORB. The proposed recognition method is applied to self-made base of 130 test images captured from different angles. Traffic signs of different shapes were also taken in consideration. Before recognition procedure, signs are classified by their color and shape. According to obtained results, the best recognition rate of 83 % is accomplished by ORB algorithm used with the extraction of the best matched features that are computed by the shortest distances between them.
